SMITHSONIAN INSTITUTION UNITED STATES NATIONAL MUSEUM
PROCEEDINGS
OF THE
UNITED STATES NATIONAL MUSEUM
VOLUME 47
WASHINGTON GOVERNMENT PRINTING. OFFICE 1915
ADVERTISEMENT.
The scientific publications of the National Museum consist of two series—Proceedings and Bulletins.
The Proceedings, the first volume of which was issued in 1878, are intended primarily as a medium for the publication of original papers based on the collections of the National Museum, setting forth newly acquired facts in biology, anthropology, and geology derived there- from, or containing descriptions of new forms and revisions of limited groups. A volume is issued annually or oftener for distribution to libraries and scientific establishments, and, in view of the importance of the more prompt dissemination of new facts, a limited edition of each paper is printed in pamphlet form in advance. The dates at which these separate papers are published are recorded in the table of contents of the volume.
The present volume is the forty-seventh of this series.
The Bulletin, publication of which was begun in 1875, is a series of more elaborate papers, issued separately, and, like the Proceedings, based chiefly on the collections of the National Museum.
A quarto form of the Bulletin, known as the “Special Bulletin,” has been adopted in a few instances in which a larger page was deemed indispensable.
Since 1902 the volumes of the series known as ‘‘Contributions from the National Herbarium,’ and containing papers relation to the botanical collections of the Museum, have been published as Bulletins.

NEW GENERA AND SPECIES OF MICROLEPIDOPTERA FROM PANAMA.
By Aucust Buscx. Of United States Department of Agriculture.
The following is the second installment‘ of descriptions of Micro- lepidoptera from Panama, based on material collected by the writer while a member of the Smithsonian Biological Survey of Panama, during two periods, from January to June, 1911, 1912.
The type material is deposited in the United States National Museum, and cotypes are, as far as possible, exchanged with the British Museum.
The citation of the type under each genus does not signify that the fixation is original in this paper, in most cases it is not; but in some as yet debatable cases the citation is necessary in order to define the author’s conception of the genus in question, and the uniform citation of the genotypes will be a convenience for future
students. Family COSMOPTERYGID.
Genus ERITARBES Walsingham.
Type.—Eritarbes otiosa Walsingham. ERITARBES GUTTATA, new species.
Labial palpi straw-yellow, with terminal joint blackish toward the face. Face, head, and thorax straw-colored. Antenne nearly as long as the forewings, straw-yellow, faintly dotted on each joint with black. Forewings shiny light straw-yellow, overlaid on exterior half with light brown; a conspicuous deep black elongate spot on the fold equidistant from apex and base of the wing; an inconspicuous dark-brown dot at the end of the fold, a few dark-brown scales at apex. Cilia straw-colored. Hindwings dark straw-colored above; underside of both wings blackish brown. Abdomen yellow. Legs whitish ochreous.
Alar expanse.—14 mm.
Habitat—Cabima and La Chorrera, Panama, May, June.
Type-specumen.—Cat. No. 16668, U.S.N.M.
Reminds one in a general way of Sttotroga cerealella Olivier.
1 The first paper was published in the Smithsonian Miscellaneous Collection, vol. 59, No. 4, 1912.

Genus PERIMEDE Chambers. Type.—Perimede errantella, Chambers.
PERIMEDE ANNULATA, new species.
Labial palpi blackish brown, terminal joint somewhat lighter. Antenne dark brown with last dozen joints silvery white. Face, head, and thorax shining black. Forewings uniformly shining black with four small deep-btack tufts of erect scales, one on the cell, one at the end of the cell, one on the middle of the fold, and one near the end of the fold, all encircled with whitish scales. Cilia gray. Hind- wings light fuscous. Abdomen dark fuscous. Legs blackish; tarsal joints very indistinctly annulated with white.
Alar expanse.—11 mm.
Halitat.—Corozal and Paraiso, Isthmian Canal Zone, March, May.
Type-specumen.—Cat. No. 15814, U.S.N.M.
Very close to Perimede particornella Busck, but of deeper black color and distinguished by the narrow white circlets around the tufts of raised scales.
Genus WALSHIA Clemens.
Type.— Walshia amor phella Clemens. WALSHIA ALBICORNELLA, new species.
Labial palpi dull ochreous, shaded with black; terminal joint nearly black with extreme apex pale. Antenne ochreous, annulated with black and with apical fourth silvery white. Face ochreous. Head and thorax ochreous, dusted with brown and black. Forewings shiny ochreous, with black and brown ill-defined markings; from base of costa to basal fourth of dorsum runs an oblique, broad, black fascia containing two large tufts of raised scales; near the end of the cell is an oblique, transverse row of raised ochreous scales mottled with black; at tornus is an ill-defined group of black and brown scales, and along the terminal edge is a row of three black dots; apical part of the wing mottled with scattered black scales; cilia light fuscous. Hindwings dark fuscous with lighter cilia. Abdomen blackish fuscous above, underside and anal tuft ochreous. Legs ochreous with broad black bars and black tarsal annulations.
Alar expanse.—10-11 mm.
Habitat.—Paraiso and La Chorrera, Panama, February, May.
Type-specomen.—Cat. No. 15813, U.S.N.M.
Very close to the type of the genus and difficult to distinguish from it except by its smaller size and the white-tipped antenne. Walshia calcarata Walsingham, which also has the white-tipped antenne, differs by the white head and the clothed posterior spurs.
NO. 2043. NHW MICROLEPIDOPTERA FROM PANAMA—BUSCK. a
Family GELECHIID FORTINEA, new genus.
Type.— Fortinea aurieiliella, new species.
Labial palpi long, thin, recurved; second joint slightly thickened with appressed scales, compressed, slightly ruffled in front; terminal joint slender, acute, as long as second. Antenne finely ciliate. Forewings very elongate, broadest just within tornus; costa straight until apical fourth, thence somewhat deflected to the well defined apex; termen but little oblique; dorsum straight; 11 veins; veins 10 and 11 so closely approximate and parallel as to unite throughout their length into one heavy vein, only separable into its constituents under magnification; 7 and 8 stalked; 7 to costa; 2 from near middle of cell; 3 from before the end of the cell; 4 from end of cell; 1 6 furcate at base. Hindwings broader than forewings; costa straight; apex pointed; termen straight, oblique; dorsum straight; 8 veins; 6 and 7 stalked; cell produced at their stalk; 5 cubital, separate; 3 and 4 separate, but approximate. Posterior tibize hairy above.
A genus of uncertain affinity though probably related to Cataleris Walsingham and Logisis Walsingham; from both of these genera it differs in having vein 9 of the forewing free and in the unusual semi- coincidence of veins 10 and 11.
FORTINEA AURICILIELLA, new species.
Labial palpi light ochreous brown. Face and head light straw- colored. Antenne light straw-colored, faintly annulated with dark brown toward their tips. Thorax light brown. Forewings light ochreous brown; extreme costal edge blackish brown; below this runs a thin, light ochreous, submarginal line from base to apex, whence it turns obliquely inward straight to the middle of the fold; this thin ochreous line is edged above with dark brown and is faintly continued along the fold to the base of the wing; it gives the wing a superficial appearance of a much narrower, elachistid wing with a long cilia represented by the tornal part; along the terminal edge is a dark brown submarginal line, beyond which the wing and the cilia are strongly metallic golden; dorsal cilia not metallic, dark greenish brown. Hindwings dark brownish fuscous with golden yellow tips; apical cilia golden yellow with a deeper yellow basal line; dorsal cilia brown. Abdomen dark brown above; underside ochreous. Legs ochreous, shaded externally with dark brown.
Alar expanse.—24 mm.

ATOPONEURA, new genus.
Type.—Atoponeura violacea, new species.
Labial palpi long, recurved; second joint thickened with appressed scales, compressed, slightly rough posteriorly; terminal joint thickened with scales except at extreme tip, compressed. Antenne three-fourths, simple. Tongue well developed, spiraled. Head and thorax smooth. Forewings elongate, narrow; costa and dorsum nearly straight and par- allel; tip of the wing rounded; apex below the median line; termen rounded; 11 veins; 7 and 8 coincident; 6 to costa; 5 to apex; 2 and 3 stalked. Hindwings broader than forewings; costa deflected beyond the middle; apex blunt; termen slightly sinuated; dorsum nearly straight; flexus prominent; 8 veins; 3 and 4 connate; 5 cubital; 6 and 7 closely approximate; crossvein between 7 and 8 at basal fourth. Posterior tibie hairy above.
Nearest to and correlated with Simoneura Walsingham and like it with vein 6 in the forewing running to costa but further advanced in having 5 to apex and 3 and 4 stalked.
The form of the labial palpi also distinguishes it from this genus. Only one other American genus is known with a similar venation in the forewing, i. e., Idiocrates Meyrick,’ which differs, however, in having vein 2 and 3 separate while the venation of the hindwings [6 and 7 parallel and 5 absent] proves it not at all related to the present genus.
ATOPONEURA VIOLACEA, new species.
Labial palpi golden metallic yellow with base and terminal joint shaded with black exteriorly. Antenne purplish black. Head and thorax bluish black, iridescent; face a shade lighter. Forewings black, overlaid with metallic, light blue scales and with a strong purplish sheen, especially toward apex, which, as well as the cilia, in certain light appear like burnished copper. Hindwing dark fuscous. Abdomen bluish fuscous. Legs bluish gray on the inside, black exteriorly.
Alar expanse.—14 mm.
Habitat—Trinidad River, Panama, March.
Type-specimen.—Cat. No. 15816, U.S.N.M.
The species appears plain black and inconspicuous in dull light, but in reflected light it is a very brilliant insect.
BELTHECA, new genus.
Type.—Beltheca prcolella, new species.
Labial palpi long, recurved; second joint thickened with scales, which are smoothly applied on the under side, but form a short brush on the upper side; terminal joint longer than second, slender, acute.
1 Trans. Ent. Soc. Lond., 1900, p. 19.

Fore wings elongate, ovate, apex round pointed, termen oblique; 11 veins: 7 and 8 coincident to costa; 6 to apex; 2, 3, 4, and 5 equi- distant; (7 and 8), 9,10, and 11 equidistant; 11 from beyond middle of the cell; 1b furcate at base. Hind wings somewhat narrower than the forewings with costa gently arched, apex produced, termen strongly sinuate, dorsum straight; 7 veins: 6 obsolete; 7 to apex; 2, 3, 4, and 5 well separated, equidistant. Posterior tibie rough haired above.
A development from Aristotelia, correlated with Chrysopora Clemens, from which it differs by the coincident veins 7 and 8 of the
forewings. BELTHECA PICOLELLA, new species.
Second joint of labial palpi whitish gray with blackish tuft; third joint black with a broad, longitudinal, silvery line and with silvery apex. Eyes in the living specimen red. Lower face silvery white; upper face and head dark iridescent brown. Thorax blackish brown. Forewing blackish brown with a thin outwardly oblique white streak- let just beyond middle of costa and with two triangular white dashes just before apex; a few scattered white scales at the end of the cell and on the fold. Cilia black; just below apex it 1s short so as to give the wing a slightly emarginate appearance. Hind wings blackish fus- cous with a bluish cast; cilia black. Abdomen iridescent blackish fuscous with silvery white underside. Legs blackish brown with white tarsal annulations.
Alar expanse.—9-10 mm.
Habitat —Cabima, Panama, May.
Type-specimen.—Cat. No. 16669, U.S.N.M.
A striking little species reminding one of the genus Apopira Wal- singham.
BESCIVA, new genus.
Type.—Besciva longitudinella, new species.
Labial palpi long, recurved, sickle-formed; second joint somewhat thickened with scales, smooth; terminal joint longer than second, pointed. Antenne shorter than the fore wings. Fore wings narrow, elongate ovate with apex pointed; 11 veins: 7 and 8 coincident to costa; 6 separate to termen; 2, 3, 4, and 5 separate, nearly equidistant ; 11 from beyond middle of cell, subobsolete toward the edge of the wing. Hind wings somewhat narrower than the fore wings with costa and dorsum nearly straight and parallel; apex produced, termen sinuated below apex; 8 veins: 6 and 7 longstalked; 6 to apex; 3 and 4 shortstalked; 5 cubital. Posterior tibise hairy above.
Allied to Untomia Busck, from which it differs in the separate veins 3 and 4 of the fore wing, the stalked veins 3 and 4 of the hind wing, and in having vein 6 of the hind wing to apex.

BESCIVA LONGITUDINELLA, new species.
Second joint of labial palpi white, barred exteriorly with light brown; terminal joint white with two indistinct brown annulations. Antenne light brown with white annulations. Face, head, and thorax white laterally with a light brown central streak. Fore wings with the white ground color strongly overlaid by light ochreous brown and black scales; a nearly continuous, longitudinal, undulating line runs through the middle of the wing from base to apex, bordered above with pure white; another black longitudinal line covers basal four- fifths of the fold; the rest of the wing area is ochreous brown, with the costal edge slightly dusted with black. Hind wings blackish fuscous with ochreous cilia. Abdomen blackish above, light ochreous on the under side. Legs whitish ochreous, dusted exteriorly with brown.
Alar expanse.—9 mm.
Habitat.—La Chorrera and Trinidad River, Panama, March, April.
Type-specumen.—Cat. No. 16670, U.S.N.M.
GALTICA, new genus.
Type.—Galtica venosa, new species.
Labial palpi long, sickle-formed, reaching far beyond vertex; sec- ond joint slightly thickened with appressed scales; terminal joint nearly as long as second, slender, acute. Fore wings elongate ovate; apex bluntly pointed; termen rounded; 11 veins; 7 and 8 coincident; 4 and 5 shortstalked from the end of the cell; 2 and 3 widely separate from before the end of the cell; transverse vein nearly obsolete; 16 furcate at base. Hind wings wider than the forewings; costa nearly straight, slightly deflected beyond the middle; apex bluntly pointed; termen and dorsum rounded; 8 veins; 6 and 7 separate, though approximate; 3 and 4 connate; 5 cubital. Posterior tibice with heavy spreading tufts of long bristly hairs above.
This genus comes nearest to Diadytica Walsingham, from which it differs in having veins 4 and 5 of the fore wing shortstalked and in having 3 and 4 of the hind wings connate, not shortstalked; more strikingly distinguished in the very remarkable hair development of the posterior tibie; those of Diadytica being nearly smooth.
GALTICA VENOSA, new species.
Labial palpi straw-yellow, with a thin, longitudinal, anterior, deep black line from base to apex, somewhat broader on the terminal joint. Face, head, and thorax purplish black, mottled with a few yellow scales. Forewings deep dull black with a broad, ill-defined, yellow band across the wing near base and with all the veins on the outer half of the wing indicated by narrow, yellow lines; an irregular aggregation of yellow scales at tornus; cilia blackish with a yellow base line. Hindwings dark fuscous. Abdomen blackish fuscous.

Type-specimen.—Cat. No. 15817, U.S.N.M.
Genus ANACAMPSIS Curtis. Type.—Anacampsis populella Clerck. ANACAMPSIS PECULELLA, new species.
Labial palpi silvery gray, shaded with darker gray, especially an- teriorly on the terminal joint. Antenne dark brown with narrow silvery annulations. Tongue silvery white. Mead and thorax dark brownish fuscous; face somewhat lighter. Ground color of the fore- wings is white but so strongly and evenly overlaid with dark brown scales as to be obscured, except under magnification; near the base is a broad, outwardly oblique, dark brown costal streak, reaching beyond the fold; on the middle of costa is a large, triangular spot, reaching to the lower edge of the cell; at the end of the cell is a small, moon-shaped, dark brown spot; just before termen and parallel with it is a broad, dark brown fascia, and between it and the discal spot is a narrower, less pronounced and slightly convex, dark brown fascia; cilia dark brown with lighter tips. Hindwings dark brown- ish fuscous. Abdomen dark brown above with each joint tipped with silvery white. Underside of body silvery white. Legs silvery white, barred and annulated with dark brown.

Ty pe-specimen.—Cat. No. 15819, U.S.N.M.
I have tried to identify this species with fuliginosa Felder and Rogenhofer, which, according to the figure, is very similar, but deem it safer to keep it under a separate name.
ANACAMPSIS PHYTOMIELLA, new species.
Second joint of labial palpi blackish green on the outer surface, whitish at apex and on the inner side; terminal joint with basal half white, except for a broad, dark green annulation and with outer half golden brown; extreme tip black. Head and thorax dark olive green; face a shade lighter green. Forewing dark green, mottled with light ocherous and blackish brown scales; on the middle of the costal edge is a black spot and at apical third is a similar spot; from both of these run faint, irregular, darker green, zigzag fascie across the wing out- wardly narrowly edged with ocherous; scattered irregularly over the wing are small tufts of blackish brown, raised scales and around apical and terminal edge is a subterminal row of black dots.

A very good example of protective coloration. All of the thirty-odd specimens were taken on mossy tree trunks in the deep forest and their colors blended so well with those of the bark, that even when I saw them alight and after they had been disturbed by a puff of tobacco smoke, I would again and again lose sight of these quite large speci- mens. On one large tree trunk near Alhajuela, where the majority of the specimens were taken, many hundred were quietly sitting and could not be detected except by making them fly up, though I knew they were there.
ANACAMPSIS BISTRIGELLA, new species.
Second joint of labial palpi black exteriorly with apical edge white; inner side of second joint and the terminal joint whitish ocherous with a black dot just before the tip. Antenne ochreous with dark brown annulations. Face, head, and thorax light ochreous fuscous. Fore- wings light ochreous fuscous with white and blackish brown markings; costal edge with three blackish markings, one from base to basal fourth with a smaller projection obliquely outward, one an obliquely out- wardly directed streak on the middle and the third a large spot cover- ing apical third of the costal edge but interrupted by a thin, white, transverse, outwardly angulated fascia across the wing at apical fourth and by two, small, perpendicular streaks beyond this fascia; at the angle of the fascia isa narrow, longitudinal, black streak; apical edge with a marginal, black streak; cell and dorsal part of the wing mottled with several, irregular, small, blackish brown spots. Hind- wings dark fuscous. Abdomen dark fuscous with light ochreous underside. Legs fuscous; tarsi blackish brown with the tips of the joints ochreous.
Alar expanse.—8-9 mm.
Habitat—Alhajuela and Cabima, Panama, April, May.
Type-specimen.—Cat. No. 15822, U.S.N.M.
It reminds one in coloration and pattern of the North American Aproerema nigratomella Clemens.
ANACAMPSIS UNISTRIGELLA, new species.
Very similar to the foregoing species though somewhat darker and more greenish in color. The costal spots are nearly contiguous; the first one smaller than in bistrigella; the second and third separated only by a thin, white streak; there is only one whitestreaklet on the costal margin beyond the fascia and the longitudinal, black streak at the angle of the fascia is surrounded by white scales contiguous with the fascia; at the end of the cell are two, elongate, black streaks and the cell and dorsal part are not mottled.

Habitat—British West Indies, F. W. Urich, coll.
Food-plant.— Crotolarva.
Type-specimen.—Cat. No. 13382, U.S.N.M. Cotype in British Museum.
Bred by Mr. Urich from the pods of Crotolaria. There has been for many years aspecimen of this species in the United States National Museum, bred by Dr. H. G. Dyar from pods of ‘‘woman’s tongue,” Acacia? sp. at Nassau, Providence Island, British West Indies, in 1891, which indicates a quite extensive range of the species.
While collating Mr. Meyrick’s descriptions of East Indian genera with my synoptic tables I recognized in his Paraspistis ioloncha, described from four Ceylon specimens my Lipatia crotolariella, described from Trinidad, and sent Mr. Meyrick a specimen of the latter for verification. Mr. Meyrick concurred in this synonymy and was good enough to give me the further synonomy of Gelechia palpigera Walsingham, described from East Africa.
This interesting species, previously also recorded by the author from the Bahamas, was taken at Alhajuela and Corozal, Panama, April, 1911.
It breeds in the pods of Crotolaria and has attained its remarkable geographic distribution with its food-plant.

Type-specimen.—Cat. No. 16683, U.S.N.M.
This large, handsome species has a noteworthy resemblance to the somewhat larger Arctiid moth, Automolis (Cratoplastis) diluta Felder.t and even more strikingly so to the Lithosiid Diarhabdosia coroides Schaus? and to the Stenomid moth, Stenoma lampyridella Busck,’ both of which were taken at the same place and at the same time as Costoma basirosella. The same coloration in all these species, though differently placed, give the same general impression at first sight; they all probably imitate a large lampyrid beetle, Cratomorphus sp., which occurred commonly at the same time and place as the last three named Lepidoptera and which both in flight and alighting resemble them very remarkably.

Family STENOMID. Genus CATARATA Walsingham.
Type.— Catarata lepisma Walsingham.
In the definition of this genus in the Biologia Centrali-Americana it is stated that vein 4 is out of the stalk of vein 2+3 in the forewings. This, however, is not the case in either of the two species described, the type C. lepisma Walsingham and C. stenota Walsingham. With the evidence of additional material the specific identity of these is apparent; the species is quite. variable; stenota was founded on two rubbed specimens in poor condition, and the name should be placed as a synonym of C. lepisma Walsingham. Types and cotypes of both are in the U.S. National Museum, and I now have a large series from all parts of Panama; the species has vein 4 approximate to but separate from 2+3.
Such is also the condition in the two following species, while in the third, C. obnubila, the veins are as described by Lord Walsingham. These modifications, which in any of the higher families, Gelechiide, Oecophoride, or Cosmopterygidx, would be definite and sound grounds for generic differentiation, I do not consider of such value in the generically far less crystalized family Stenomide.

Genus ATHLETA Walsingham.
Athleta WALSINGHAM, Biologia Centrali-Americana, vol. 4, Heterocera, 1912, p. 155.
Type.—Athleta trisecta Walsingham.
In the description of the genus Athleta vein 2 of the forewing is given as separate and distant from vein 3. Such, however, is not always the case in the type species under consideration. With several additional specimens from Porto Bello and Trinidad River, Panama, it is found that this character is not stable within the spe- cies, but that vein 2 may be separate, connate, or even short stalked with vein 3. Similar instability of these veins within the species is found in other groups of this family and makes the character of little value generically. The genus Athleta may, however, be separated from its nearest ally, Catarata Walsingham, by the anastomosis of veins 2 and 1c, which appears to be constant; from whatever start- ing point vein 2 runs nearly at right angles downward and into vein 1c, separating from it again just before tornus. The male of this species, which was not known at the time of the description, has a very noticeable short fold along vein 1 of the hindwings, which contains a large expansible tuft of yellowish hairs

Genus JONACA Walker.
Type.—Jonaca compulsana Walker.
Though Walker’s generic descriptions are entirely inadequate for present day requirements and though my generic notes on the type of his genus Jonaca, made several years ago, are unfortunately not full enough for absolute determination, I feel reasonably safe in applying this name to the following species, which has the general habitus of the type of the genus. Below are given the generic characters of the present species, which I believe also apply to the type of the genus, J. compulsana Walker; a cursory examination of the type of this species in the British Museum will easily determine this. Labial palpi curved, ascending, hardly reaching vertex; second joint some- what thickened with appressed scales; terminal joint short, bluntly pointed. Face, head, and thorax smooth. Antenne short, stout, simple. Forewing with costa nearly straight, slightly deflected from apical third; apex blunt; termen rounded; tornus rounded; dorsum straight; cilia short; 12 veins, all separate; 2 from near end of cell; 3, 4, 5, equidistant, approximate from end of cell; 7 to termen; 11 from the middle of the cell; no secondary cell; 1b furcate at base. Hindwing broader than the forewing, roughly triangular with rounded apex; 8 veins; 3 and 4 connate; 5, 6, and 7 parallel. Posterior tibie with short tufts of hair above the spurs. Body stout.
Allied to Rhobonda Walker, which differs in having an internal vein in the cell, vein 11 from near the base and vein 2 from near the middle of the cell.

Abdomen and legs golden yellow; claspers and uncus very long, nearly a third of the abdomen.
Alar expanse.—12 mm.
Habitat—Cabima, Panama.
Type-specimen.—Cat. No. 16766, U.S.N.M.
Female.—Not known but probably much larger. The species has the venation of the present genus, but the wing ornamentation of Cnissostages Zeller, which is not known to me except through descrip- tions and figures. Mr. Durrant states that this latter genus has vein 9 and 10 in the forewing stalked with 8 free, and if this proves a constant character it will amply separate the ne genera, which, how- ever, are closely related.
C fiesestane is also a fungus feeder, according Zeller, on Boletis
arborum. Family TINEIDA.
HARMACLONA, new genus.
Type.—Harmaclona cossidella, new species.

A large, typical, narrow-winged species, close to S. coloradella Dietz, but without any dorsal ochreous markings.
SCARDIA MINIMELLA, new species.
So nearly identical in coloration and markings to the foregoing species as to suggest their identity, but only about half the size ot S. asthmella. The only difference seems to be the more clearly defined costal geminate spots, the lighter underside of the wing, and the lighter colored abdomen of S. minimella, all of which might be variation only. Such extreme variation in size, however, is not normal within this genus, and it is clearly obligatory, as well as undoubtedly correct, to consider them distinct.

[SCIENTIFIC RESULTS OF THE PHILIPPINE CRUISE OF THE FISHERIES STEAMER “ALBATROSS.” 1907-1910.—No. 31.]
NEW SPECIES OF CRABS OF THE FAMILIES GRAPSID AND OCYPODID.
By Mary J. Ratruesun,
Assistant Curator of Marine Invertebrates, United States National Museum.
The new species and subspecies here described will be illustrated in the final report on the collections obtained in Philippine and adjacent waters during the years 1907-1910 by the steamer Albatross of the United States Bureau of Fisheries.
The new forms are as follows:
Varuna altimana.
Ptychognathus guijulugani.
Sesarma (Sesarma) palawanense.
Sesarma (Sesarma) vicentense.
Sesarma (Sesarma) mindanaoense. Sesarma (Sesarma) edwardsi philippinense. Sesarma (Sesarma) xquifrons.
Sesarma (Sesarma) tectum.
Sesarma, (Holometopus) limbense.
Sesarma (Parasesarma) dumacense. Sesarma (Parasesarma) moluccense jamelense. Sesarma (Parasesarma) pangauranense. Macrophthalmus sandakani.
Dotilla sigillorum.
Tympanomerus philippinensis.
The genus Varwna' is expanded to include those species of Ptychognathus in which the front is prominent, sublaminar, its margin horizontal and distant from the anterior border of the antennular cavities; the antero-lateral teeth well-marked and acute; the upper surface of the wrist subquadrilateral and armed at the inner angle with a tooth or spine; all of which characters are common to typical Varuna. The species added to Varuna resemble Ptychog- nathus in having the exognath wider in the male than in the female.

ee The genus Varuna as now modified comprises the following species: Varuna litterata (Fabricius, 1798). Type-species. Varuna tomentosa Pfeffer, 1889. Varuna dentata (de Man, 1892). Varuna spinicarpus (Ortmann, 1894). Varuna polleni (de Man, 1895). Varuna affinis (de Man, 1895). Varuna onyx (Alcock, 1900). Varuna altimana Rathbun, 1914.
Family GRAPSIDA.
Subfamily VARUNIN 42. VARUNA ALTIMANA, new species.
Type-locality Point Jamelo, Luzon; river, in 20-foot seine; July 13, 1908; 1 male.
Type.—Cat. No. 44558, U.S.N.M.
Dimensions.—Male type, length 20.7 mm., width 21.8 mm.
Surface uneven; H-depression deep; a groove either side of the intestinal region; a transverse groove runs inward behind the second and bebind the third tooth; frontal and hepatic regions depressed; surface finely punctate and covered with still finer reticulating lines formed by flattened, confluent granules. Front broad, prominent, feebly bilobed, its lateral margins making an obtuse angle with the anterior margin. Upper border of orbit strongly S-shaped, forming at its union with the front a closed fissure ending in a triangular sinus. Antero-lateral margins moderately convergent, 3 teeth acute, with straight sides and separated by deep, narrow sinuses. Postero- lateral margins subparallel, slightly sinuous; a granulated line, beginning a little ways from the margin and considerably behind the last lateral tooth, forms the upper boundary of the very short and broad obliquely-vertical section of the branchial region.
Antennules obliquely folded; nasal lobe triangular. Sides of ischiognath parallel; in the male the exognath is large and much swollen; reaching nearly to the end of the merognath and one and three-fifths times as wide as the ischiognath; in the female the exognath is much flatter and narrower, being not quite so wide as the ischiognath.
Chelipeds stout in male; a fringe of hair on upper and inner edges of merus; carpus with a long spine which is triangular at the base, the tip acuminate, a tubercle at base of spine, just below anterior margin of segment; palms high, postero-inferiorly much swollen, posteriorly rugose; upper margin compressed and elevated in a flat lobe occupying the proximal two-thirds; fingers very broad and flat, narrowly gaping; immovable finger horizontal, with a blunt longi- tudinal ridge continued almost imperceptibly on the palm, and a
NO. 2044, - NEW PHILIPPINE CRABS—RATHBUN. 71
sinus in the prehensile margin near the tip, teeth 9-11; dactylus strongly arched, armed with about 13 irregular teeth. Chelipeds of female weak, the palm and fingers each with a well-marked ridge.
Legs narrow; margins hairy; last 3 joints heavily fringed below; a sharp, subdistal spine on merus.
Abdomen of male subtriangular; terminal segment one and one- half times as long as its middle width.
This species is nearest to V. affinis (de Man)' but has a more sinuous orbital margin, a different-shaped maxilliped (exognath wider, and ischiognath not widening distally), a longer, slenderer carpal spine, a lobe on upper margin of hand, a gape between the fingers.
V. spinicarpus? has a more even carapace; less sinuous orbital margin; nasal lobe with sides angled, not straight; hand without a lobe above; merus-joints of legs with a small, inconspicuous spine; abdomen of male narrower.
The lateral margins of the carapace are less incurved anteriorly than in V. tomentosa * or litterata* so that the carapace is squarer. The union of the anterior with the lateral edges of the front makes more of an angle than in either of those species, where the corners are rounded off.
PTYCHOGNATHUS GUIJULUGANI, new species.
Type-locality.—Guijulugan, Negros; April 2, 1908; 2 males, 2 females, adult (1 female ovig.).
Type.—Cat. No. 44668, U.S.N.M.
Dimensions.—Length of largest male, 8 mm., width 9.3 mm. Length of ovigerous female 8 mm., width 9 mm.
Associated with P. barbata at Guijulugan, were four specimens of a closely allied species.
Carapace a little broader than long, flat, regions indistinct; post- frontal tubercles well marked; the oblique portion of the branchial region is separated from the horizontal portion by a fine granular line in the posterior half.
Front sinuous, prominent, half as wide as greatest width of cara- pace; edge without a line of granules.
Antero-lateral teeth 3, blunt, the first or orbital tooth the longest, the last tooth very small; teeth not projecting sideways, sinuses triangular.
Upper border of orbit sinuous and oblique. The antennules fold nearly transversely. Epistome very narrow, almost linear; posterior border crenulate.

72 PROCEEDINGS OF THE NATIONAL MUSEUM. VOL. 47.
The maxillipeds are situated a considerable distance back of the edge of the buccal cavity.
Exognath broader than ischiognath in both sexes, more so in male than in female; ischiognath with subparallel sides; antero-external lobe of merognath very broad.
In the male the inner angle of the wrist is rectangular, not toothed; hand massive, with a squarish patch of hair at the distal end, which is continued part way on the fingers. The dactylus is a little more than twice as long as the upper margin of the palm, is finely toothed, and when closed leaves a gap between it and the horizontal fixed finger; the latter has fewer teeth, 2 or 3 of which near the middle are large. In the female the wrist bears an equilateral, acute tooth at its inner angle, the chela is weak, with a well-marked granulate ridge above the lower margin, and grooved fingers; near the tips there is on the inner and outer surfaces a row of short hairs which are appressed against the horny tips.
Legs rather narrow; no spine on meropodites; last 2 joints moder- ately hairy; the second and third pairs are about one and three- fourths times, the last pair one and one-fourth times, the length of the carapace.
Differs from P. barbata' in having the carapace a little narrower; front more advanced and less deflexed, lacking the double row of granules in that species; upper line of orbit more oblique and more sinuous; epistome about half as wide; distance between epistome and maxillipeds greater; in the male the exognath is wider, ischiog- nath narrower, and lobe of merognath larger, than in barbata; these characters are present, though less marked, in the female; inner angle of wrist of male squarer, inner distal margin of wrist shorter, so that upper surface of wrist is more oblong than in barbata (this differ- ence less evident in female); in the presence of a row of short hairs about the ends of the fingers in the female.
Subfamily SHSARMIN A. SESARMA (SESARMA) PALAWANENSE, new species.
Type-locality.— River, Nakoda Bay, Palawan Island; December 31, 1908; 3 adult females, 1 of which is ovigerous.

No. 2044, NEW PHILIPPINE CRABS—RATHBUN. 73
Carapace a little broader than long, narrowing behind, the sub- rectangular epibranchial tooth at some little distance behind the acute orbital angle, the margin behind the second tooth slightly con- cave. Surface covered with tufts of coarse hair, intervening spaces smooth except for the customary granulate lines on the postero-lateral portions. Regions deeply separated from one another. Postfrontal lobes separated by deep and wide U-shaped sinuses, of which the median is much larger than the lateral; submedian Iobes more than one and one-half times as wide as outer lobes. Surface of front very much as in 8. teniolatum White, being concave and smooth except for a few tubercles; lower margin very sinuous. Upper margin of orbit long and sinuous and directed backward to the orbital tooth.
Upper margin of merus of cheliped armed with a large flat sub- distal tooth; inner margin sparingly denticulate or spimose and expanded distally in a broad tooth. Outer surface of merus and carpus covered with granulated lines and tubercles; inner angle of carpus armed with a subrectangular tooth; outer and upper surface of propodus covered with tubercles, which for the most part are depressed and separated by reticulating grooves; fingers devoid of granules or tubercles except on the upper part of the dactylus; upper margin of palm thin, crossed by short, crowded and nearly longitudinal lines of granules, close to which runs a single line of smaller granules extending from the articulation with the carpus to the tooth at the distal end of the upper margin; no pronounced transverse elevation on inner surface of palm, but a feeble trace of a ridge; this surface is sparingly dotted with granules; fingers with a narrow gape (in the female), prehensile edges furnished with low uneven teeth; upper edge of dactylus margined, and milled incon- spicuously on the proximal half with about 25 grooves which stop short of the basal end.
Ambulatory legs broad; third pair one and two-thirds times as long as carapace; merus joints broad, that of third pair a little over twice as long as broad, and armed with a strong, acute subdistal tooth; propodi long and dactyli short, the latter seven-tenths as long as the former in the third pair.
Terminal segment of female abdomen a little longer than wide and so deeply invaginated in the sixth segment that the latter reaches nearly as far forward as does the terminal segment.
Closely allied to S. teniolatum from which it differs in its longer and narrower carapace; narrower front; in the greater difference in the width of the outer and inner frontal lobes; in the granulate, not pectinate, ridge near the upper margin of the palm, which is closer fo that margin and not straight but follows the slight curve of the margin; and in the absence of a transverse ridge inside the palm.

Our species resembles also S. lafondii Hombron and Jacquinot,! which has a similar ornamentation on the upper margin of the palm, no ridge inside the palm, but the upper margin of the movable finger entirely smooth; in this last character, S. palawanense is intermediate between teniolatum and lafondw. The latter has an even broader carapace than teniolatum, and its side margins are parallel instead of convergent.
SESARMA (SESARMA) VICENTENSE, new species.
Type-locality.—Port San Vicente (Luzon side), Palaui Island, off northern Luzon; beach; Nov. 15, 1908; 1 male.
Type.—Cat. No. 45758, U.S.N.M.
Dimensions.—Male, length 8.8 mm., width at orbital angles 9.2 mm., posterior or greatest width 9.7 mm., width of front 4.6 mm.
A small, square species with 3-toothed side margins and a vertical front. Carapace a little wider than long, sides nearly parallel but slightly diverging posteriorly, and a little concave behind the third tooth; dorsal surface almost flat, except near the front and postero- lateral corners; regions delimited, surface roughened with crowded flattened granules anteriorly and with confluent grooves and pits posteriorly; on the hepatic and anterior branchial regions there are also unequal bead-granules. Suprafrontal lobes nearly transverse, separated by very small emarginations, the lobes of the inner pair a little more than one and one-half times as wide as those of the outer pair; from these lobes the front descends abruptly, lower margin horizontal, sinuous with two broad, shallow lobes and an equally broad median sinus; sides of front parallel, lower corners rounded, surface finely granulous, a tubercle on each side near the lower margin almost in line with the notch between the outer and inner postfrontal lobes.
Upper margin of orbit inclined obliquely backward and outward to the acutangled antero-lateral tooth; this is separated by a well- marked notch from the second tooth which is small and obtusangled; the third tooth is simply a smooth swelling of the margin.
Epistome covered with vesicular pubescence. Merus of outer | maxillipeds equal in length to the ischium, its antero-lateral angles rounded off.
Only the left cheliped is present and that is rather small, not one and one-half times as long as the carapace. Lower and inner margins of merus denticulate, outer surface covered with short ruge, upper margin formed by parallel, oblique rugee. Upper surface of carpus crossed by granulated ruge, inner angle bluntly rounded. Outer surface of hand nearly smooth, punctate, upper surface covered with sharp granules, and near the margin, with obliquely longitudinal and

broken lines of granules; upper half of inner surface sparingly granu- lous, no transverse ridge present. The fingers do not gape when closed, although the irregular teeth do not fit snugly together; the upper margin of the dactyl bears 6 spinules on the proximal half.
Merus joints of legs diminishing toward both ends, upper surface roughened with fine granules, anterior margin with a short subdistal tooth tipped with a back bristle, merus of third pair about two and three-fourth times as long as wide. Last three joints narrow, bor- dered with dark bristles; dactyli nearly straight till near the tip, a little longer than their respective propodi.
In the male abdomen the margins are concave from the beginning of the fourth to the beginning of the sixth segment; terminal segment large, as wide as long, and as wide as the adjoining end of the sixth segment.
This species is most nearly related to S. sinense Milne Edwards! It differs from sinense in its narrower front, only half as wide as the dis- tance between the orbital angles, in having a third tooth on the side margins, in the middle part of the outer surface of the palm being nongranulate, and in the absence of a transverse granular line on the inner surface.
SESARMA (SESARMA) MINDANAOENSE, new species.
Type-locality——Small stream south of Cotabato, Mindanao; May 20, 1908; 1 female.
Type—Cat. No. 45765, U.S.N.M.
Dimensions.—Type female, length of carapace 18.2 mm.; width at antero-lateral angles 19 mm., width at postero-lateral angles 20.2 mm., width of front 11.2 mm., height of same 2.3 mm., length of pro- podus of cheliped below 9.4 mm., same above 3.3 mm., height of same 4.2 mm., length of merus of third leg 15.6 mm., width of same 6 mm.
Carapace convex, regions well marked, especially the mesogastric and the cardiac; a groove parallel-to the gastro-cardiac groove cuts off a narrow strip of the mesogastric region except across the middle; surface rough with coarse pits and fine grooves; from most of the pits a bunch of short hairs arises; one of these bunches is situated on each of the 4 tubercles behind the postfrontal lobes; the tubercles of the outer pair are further forward than those of the inner pair and are nearly the size of the postfrontal lobes. These lobes are deeply and widely separated, the outer ones three-fifths as wide as the inner ones; the intervening furrows are continued well back on the carapace; sides of front parallel, lower rim projecting, in dorsal view bilobed and with a broad median sinus, in front view arcuate and a little sinuous. Upper margin of orbit oblique, orbital angle acute; outer margin of orbital tooth sloping backward and inward; next lateral

Third leg about two and one-half times as long as carapace, its merus over two and one-half times as long as wide; a sharp spine above each merus; margins of last two segments and distal end of carpal segments furry; dactyli with long horny tips, definitely shorter than their respective propodi in the second and third legs, a very little longer than the propodi in the first and fourth pairs.
Near S. modestum de Man?! and S. longipes Krauss.?, From both it may be recognized by the wider front, different slope of the orbital tooth, smoother hands, longer merus joints of the legs; from the second by the shorter dactyli of the legs.
SESARMA (SESARMA) EDWARDSI PHILIPPINENSE, new subspecies.
Type-locality—Pangauran River, Port. Caltom, Busuanga Island; Dec. 15, 1908; 3 males, 3 females (1 male is type); also Dec. 16, 1908, 1 female with Rhizocephalid parasite under the abdomen.
Type—Cat. No. 45750, U.S.N.M.
Dimensions.—Type male, length of carapace 14.5 mm., width between the orbital angles 16.7 mm., width of front 9.6 mm.
This subspecies has a little wider carapace than typical edwardsi; the chele are narrower, the fingers more elongate and more hori- zontal; the abdomen of the male with the terminal segment deeply inserted in the sixth segment.*
Variety brevipes de Man‘ has a male abdomen similar to that of philippinense, but has much shorter legs. The legs of the Philippine form are as in typical edwardsi.®

Dimensions.—Male, length of carapace 9.6 mm., width at epibran- chial tooth 11.4 mm., width at anterior angles 11.2 mm., width at posterior angles 10.7 mm., width of front 7.2 mm., height of front 1 mm., length of third ambulatory leg 6.5 mm., width of same 2.9 mm.
Distinguished by the slightly marked frontal lobes and the well- defined upper surface of the palm.
Carapace sensibly wider than long, wider anteriorly than poste- riorly, widest at the single epibranchial tooth, lateral margins a little concave; surface everywhere punctate, mesogastric region defined, as is also the posterior cardiac lobe; oblique lateral lines few, about seven, the anterior of these crossing the epibranchial tooth. Front very wide, widening below, superior lobes separated by shallow fur- rows, the lateral ones very short; outer lobes a little narrower than inner; surface of front nearly vertical, lower margin arcuate, although nearly straight at the middle. Upper margin of orbit directed very obliquely backward to the short and slightly advanced orbital tooth; next tooth subrectangular.
Maxillipeds widely gaping, the merus joints obliquely transverse. Chelipeds of male unequal; outer surface of arm, wrist, and proximal half of palm crossed by fine granulated rugee which on the middle of the palm are longitudinal; no spine on upper margin of arm, only a blunt angle; inner margin sparingly denticulate and with a shallow rounded prominence; no tooth at inner angle of wrist; chele punc- tate; upper surface of palm flattened, limited outwardly by a smooth blunt ridge and inwardly by an uneven granulated margin; a trans- verse line of granules inside palm, otherwise surface nearly smooth. Fingers moderately gaping; the horny extremity embraces the sub- terminal tooth on each finger; upper margin of dactylus with a line of four distant spinules; lower margin of immovable finger straight except at tip; prehensile edges irregularly toothed, three teeth on each finger enlarged.
Ambulatory legs of moderate length; carpal and propodal segments densely hairy.
Abdomen of male narrow, with a large terminal segment which is nearly as wide as long.
Resembles the very briefly described S. lave A. Milne Edwards ! in its smooth shining carapace, but the carapace is narrower than in leve (where it is 7 mm. X 10 mm.), and the front has not a straight margin.
The carapace has considerable resemblance to that of S. semperi Birger,? but the legs are shorter, the palm has no transversely ob- lique ridges above, and the movable finger is very feebly ornamented on the upper margin, instead of having stout tubercles.

SESARMA (SESARMA) TECTUM, new species.
Type-locality— Port San Vicente, Palaui Island, off northern Luzon; seine; Nov. 14, 1908; 1 female adult.
Type.—Cat. No. 45766, U.S.N.M.
Dimensions.—Type female, length 18.3 mm., width at antero- lateral angles 18.4 mm., greatest width (at middle of carapace) 20.2 mm., width of front 12 mm., height of front 3.7 mm., length of pro- podus of cheliped 9.2 mm., height of same 4.8 mm., superior length of palm 3.6 mm., length of merus of third leg 14.3 mm., width of same 5.3 mm.
This crab is densely covered with pubescence everywhere except on the cornex, the terminal half of the fingers and the horny tips of the legs; tufts of longer hairs are disposed on carapace, chelipeds, and legs, including a tuft on each tubercle.
Carapace almost square, except for the two lobiform teeth which project laterally beyond the orbital tooth and make the carapace wider at those points. Regions limited by wide grooves. The prin- cipal tubercles are as follows: One large, behind each frontal lobe, the middle pair further back than the outer pair; one in the middle of the mesogastric region, and one on each side and nearly in the same line on the protogastric region; two side by side on the cardiac region; about three on each branchial region. Before the hairy coat is removed the tubercles seem to be more numerous. The surface is in the main smooth and shining, and there are no oblique ridges on the postero- — lateral regions. Frontal lobes prominent and deeply separated, the outer a little narrower than the inner. The front widens from above downward, is lowest at the outer ends and most prominent along the lower margin; this last is convex in front view, but sinuous from above, showing six shallow prominences; surface of front uneven. Upper margin of orbit very oblique; orbital tooth very slightly advanced, outer margin convex.
Chelipeds of female equal, of moderate size. Merus with a subter- minal tooth on upper margin, and a slight prominence but no tooth on the inner margin. Outer surface of carpus covered with low tuber- cles; inner angle blunt. Chele, when hair is removed, smooth and shining, without ornamentation in the way of granules or lines but with two or three depressed and inconspicuous tubercles on upper surface, and fine puncte in a reticulating pattern where the hairs are inserted; upper margin of palm blunt; lower margin of propodus nearly straight; fingers slender, prehensile edges finely toothed as far as to the horny extremities which occupy the distal third and are slightly notched where the tips cross each other. Merus joints of the legs bordered by irregular tufts of hair which have the appearance of lobes; a subterminal tooth on anterior margin; the tufts of hair on the upper surface of merus, carpus, and propodus

look like granules or tubercles, but when they are removed the surface is seen to be glossy and in the main smooth though a little uneven; dactyli shorter than propodi, tapering to a very slender horny tip.
Terminal segment of abdomen of female inserted up to its middle in the sixth segment.
S. tectum, in the absence of rugose lines on the postero-lateral por- tions of the carapace, in the shining surface, lack of roughness or granulation, coat of sete and hairs, resembles S. lanatum Alcock,* but the latter has a considerably wider carapace, with the tufts of hair smaller, more numerous and more uniform.
SESARMA (HOLOMETOPUS) LIMBENSE, new species.
Type-locality.—Limbe Island, Gulf of Tomini, Celebes; November 12, 1909; 1 male (type), 2 females (1 ovigerous).
Type.—Cat. No. 45920, U.S.N.M.
Dimensions.—Male type, length of carapace 6.8 mm., width at antero-lateral angles 7.7 mm., width at postero-lateral angles 7.2 mm., width of front 4.4 mm.; ovigerous female, length of carapace 11.7 mm., width at antero-lateral angles 12.9 mm., width at postero- lateral angles 12.7 mm., width of front 7 mm.
Carapace deeply sculptured; not only are the interregional grooves deep, but the grooves separating the postfrontal lobes are continued halfway to the mesogastric region, and the branchial region shows several areolets along itsinner border. Surface punctate and shining, with numerous very short and inconspicuous hairs. The antero- lateral tooth projects forward but not outward. Where the foremost of the oblique ridges joins the side margin, the latter is a little swollen. The front. is about 4 times as wide as high, surface concave, sides converging below, lower margin slightly sinuous, and in front view, arcuate as well; a bunch of coarse granules near the middle of either half. Postfrontal lobes somewhat oblique, outer pair slightly nar- rower than inner pair.
Arm without spine above; inner margin with a triangular tooth denticulated on the edge. Palm rather smooth, sparingly punctate, with fine rug near the wrist and sparse granules near the top; upper margin a single slightly angled, granulated line running obliquely backward and outward from the distal angle of the palm to the point where it curves down to the articulation of the wrist. Within this margin and forming part of the inner surface, although visible from above, there are 2 or 3 granulated lines, the upper of which is, in the male, parallel to the upper margin; the others are also oblique but not parallel. The upper margin of the finger bears 8 or 9 scalari- form tubercles in the male; in the female the tubercles are low and only 5 or 6 proximal ones are discernible.

80 PROCEEDINGS OF THE NATIONAL MUSEUM. vou. 47.
Legs long and narrow, the third pair more than twice as long as the carapace, and its merus two and one-third times as long as wide. The spine on the upper margin of the merus-joints is acuminate. The propodites are unusually long, the anterior margin of the third one being 4 times as long as its greatest width; the dactyls, on the other hand, are rather short, that of the third leg about two-fifths as long as the propodus. The dactyli are of uncommon form, convex on the anterior margin and also, but very slightly so, on the posterior margin, down to the long-pointed tip.
This species has no resemblance to any other of the subgenus Holometopus, but its general aspect is much like that of a Samoan species of the subgenus Parasesarma, which I shall describe later.
SESARMA (PARASESARMA) DUMACENSE, new species.
Ty pe-locality.—Dumaca River, Luzon; February 25, 1909; 1 female, thin-shelled.
Type.—Cat. No. 45922, U.S.N.M.
Dimensions.—Type female, length of carapace 13.2 mm., width between antero-lateral angles 17.6 mm., width between postero- lateral angles 15.7 mm., width of front 9.8 mm., length of propodus of cheliped below 7.9 mm., same above 3 mm., height of same 3.4 mm., length of merus of second leg 10.7 mm., width of same 4.8 mm.
Allied to S. plicatum.. The sides of the carapace are slightly con- cave; the antero-lateral tooth is acute; its outer margin does not curve inward toward the tip as in S. plicatum, but the tooth projects strongly outward. The interregional grooves are very deep, as are also the grooves separating the postfrontal lobes; these grooves are continued back nearly to the angles of the mesogastric region. On each branchial region there is a smooth longitudinally oblique ridge running near the side of the cardiac and intestinal regions. The lateral margins of the deflexed front converge below, while in plicatum they diverge; that part of the front lying before the antennules is very swollen. The propodus of the cheliped is more slender than in the female of plicatum; on the upper surface of the palm there 1s a pectinated ridge beginning at the distal inner angle of that surface and running in a longitudinally oblique direction, not in a trans- versely oblique direction, as in plicatum; parallel to this ridge there is a fine granulated ridge near the posterior margin. The protuber- ances on the upper margin of the movable finger are low and scalari- form; there are about 7 on the proximal half, after that they become very faint; each one is divided by a transverse line into a large proximal portion and a small tuberculiform distal portion. The anterior or upper margin of the meropodites of the ambulatory legs ae oe Ns ee ee eee

is less convex in the distal half than in plicatum, so that the segment is wider distally than in that species.
Color.—In alcohol the carapace is blotched, and the legs finely mottled, with dark on a light ground.
SESARMA (PARASESARMA) MOLUCCENSE JAMELENSE, new subspecies.
Type-locality—Point Jamelo, Luzon, in river; taken in 20-foot seine; July 13, 1908; 2 males, 2 females (1 male is type).
Type.—Cat. No. 45917, U.S.N.M.
Dimensions.—Type male, length of carapace 10 mm., width between antero-lateral angles 11.3 mm., width between postero- lateral angles 10.8 mm., width of front 6.6 mm., length of propodus of cheliped below 7 mm., same above 3 mm., height of same 4 mm., length of merus of third leg 7.7 mm., width of same 3.4 mm.
This form differs from typical moluccense de Man,' in having the carapace a little narrower in proportion to its length; in the front also narrower in proportion to the width between the antero-lateral angles; in the 9 or 10 tubercles on the upper margin of the movable finger being obliquely transverse instead of longitudinal, each tubercle trending forward or distally toward the inside of the finger, as in S. lenziit de Man.?
As in the typical species, the carapace is widest at the anterior angles; the surface of the front bears an elongated transverse tubercle near the lower margin on either side of the middle, and a round tubercle underneath the outer corner of the postfrontal lobes of the inner pair; the upper margin of the arm has no subdistal spine, only an obtuse tooth, the lower margin has a triangular expansion with denticulate border, and a spine or sharp tooth at the angle; the upper surface of the
