Strohecker Through the kindness of Dr. E. A. Chapin and other officials ofthe U. S. National Museum, I have had opportunity to study some ofthe endomychids in the collections of that institution. Althoughcomparatively few in number, these have proved of considerable in-terest and include a number of new species. In addition, the follow-ing records are of note : Eumorphus marginatus (Fabricius) : A single male specimen from Baguio,Luzon, P. I.Eumorphus tetraspilotus Hope: A male and a female from Palawan, P. I.Cyclotoma pardalina (Gerstaecker) : Eleven specimens from Mindanao, P. I.These are indistinguishable from specimens from Java, the type "locality."Cyclotoma testudinaria Mulsant: Three specimens from Palawan. I suspectpardalina and coccinellina are color varieties of testudinaria.Genus BECCARIA GorhamBECCARIA SEPTEMGUTTATA, new speciesFigure 12, kHighly convex, black and shining, with the lateral portions of thepronotum, three rounded spots on each elytron, and a median spotcommon to both elytra reddish yellow. Head and antennae, exceptbasal three or four joints, black. Under surface black except meso-sternum and prothorax, which are yellow. Legs black with piceoustinge.

Pronotum three times as broad as long, finely,evenly, and not closely punctured, narrowly margined; basal foveaeminute, very shallow; between these the pronotum is finely margined.Elytra sparsely and coarsely punctured, especially in the regions ofthe scutellum and humeri; the punctures finer toward apex.Type.?U. S. N. M. No. 55878.Type locality.?Surigao, Mindanao, P. I. (C. F. Baker). Pos-sibly the same as B. septemmaculata Pic from Malacca but a littlesmaller and with the legs black. Length 3.5 mm., width 1.75 mm.BECCARIA DENTICORNIS, new speciesGenerally similar to the preceding but differs in several features,including size. Antennae entirely black, joints 2 to 6 longer thanwide; joints 9 and 10 triangularly acuminate internally; joint 11 oval.Head black. Pronotum three times as broad as long, finely marginedat sides and base ; basal foveae minute and shallow. The pronotum isblack at base between the foveae and has a median black area extendinganteriorly to the front margin, leaving the sides broadly yellow. Thelight spots of the elytra are arranged as in B. septemguttata, but thetwo anterior ones are quite elongate and the median common one ismuch smaller. The punctures of the elytra are very coarse in the hu-meral and scutellar regions. Legs, epipleurae, and the epimera andlateral area of metasternum sooty. Otherwise the under surface isdull yellow. The metasternum is very coarsely punctured towardthe middle. Length 4.5 mm., width 3.5 mm.Type.?U.S.N.M. No. 55879.Type locality.?Island Samar, P. I. (C. F.

Entirely black except the abdomen, whichis reddish yellow, and the elytra, which are steel-blue. Each elytronbears, just behind the humeral callus, a transverse yellow bar, whichclosely approaches the lateral margin but is separated from the sutureby about its own breadth. This bar is twice as wide as long. Theantennae are half as long as the body, slender, joint 3 three times aslong as joint 2 but not much longer than 4; joints 2 to 8 progressivelyshorter. Club distinct but gradually formed, not much longer thanjoints 6 to 8 together; joint 11 transverse, truncate. Head, thorax, SOME ENDOMYCHID BEETLES STROHECKER 383and elytra finely and sparsely punctured and finely alutaceous. Eachpuncture bears a minute seta. Thorax with sides almost straight, con-vergent from the acute hind angles to the acutely produced frontangles, narrowly margined. Lateral sulci deep, curved, and reachingalmost to middle of disk, basal sulcus broad, deep. There is a circulardepression within the hind angle. Scutellum as long as broad,rounded behind. The elytra are slightly depressed at the scutellum,elongate, little wider at base than the pronotum but broadening grad-ually to posterior third, thence evenly convergent; tips separatelyrounded. Legs long and slender, femora subclavate. Length 4.75mm., width 2.6 mm.Type.?Female, U.S.N.M. No. 55880.Type locality.?Tat-sien-lu, Szechwan, China (D. C. Graham).A single male specimen, allotype (author's collection), closely re-sembles the type but is a little larger, has the sides of the pronotumstraight, and the front tibia bears a low, blunt tubercle on its innerface at the distal third. Data same as for type. I have not used themale as the type because all its tarsi are damaged. This distinctivespecies is unusual for a Mycetina, but the mouth parts and triangularmesosternum lead me to refer it to that genus. It belongs to the sec-tion that includes Af. niarginalis (Gebler) [= obliquesignata Gorham]and the species that have been referred to Phaeomychus.Genus ENGONIUS GerstaeckerENGONIUS EXCISIPES, new speciesFlGUKE 12, hHighly convex for the genus, glabrous, moderately shining, ofbronzy color, each elytron with a small yellow spot on the posteriorpart of the humeral callus and another of equal size at the same leveland halfway between the callus and suture, and a yellow crossbarbehind the middle. The crossbar is bidentate anteriorly and uniden-tate (internally) posteriorly and is equally removed from the lateralmargin and suture. Antennae black, slender, joint 3 twice as long as 4,club broad, flattened but hardly compact. Antennal ridges of headvery prominent. Pronotum strongly transverse, its front angles pro-duced and acutely rounded, sides narrowly margined, rather deeplysinuate behind the middle, hind angles divergent and acute. Basalfoveae very deep and short, basal sulcus fine and deep. Disk of pro-notum finely, sparsely punctured, the punctures thicker and coarserat sides. The front margin has a very broad membrane.

Disk of pronotum evenly, moderately convex, min-utely and sparsely punctured, its pubescence sparse and erect. Scutel-lum transverse. Elytra three times as long as pronotum, as wide atbase as pronotum, thence gently and slightly widened, gradually con-vergent to apex, moderately convex, coarsely, sparsely and shallowlypunctured, pubescence sparse and semierect. The elytra are shiningand black except a very narrow basal border, a wider sutural stripeand a still wider marginal stripe, which are red. The red areas arecontinuous with each other. Length 3 mm.Type.?Male, U.S.N.M. No. 55885.Type locality.?Ma-Ao, Occidental Negros, P. I., at light (W.Dwight Pierce).An unusual type among the oriental species of Stenotarsus. Itsgeneral appearance is strikingly similar to that of S. militarisGerstaecker from Mexico, except the new species lacks the black patchon the pronotum.STENOTARSUS FLAVOMACULATUS, new speciesLong-oval, strongly convex, black and moderately shining with theumbo, an anterior juxtasutural spot and a postmedian transverse baron each elytron reddish yellow. Antennae a little longer than headand pronotum, black except for the first two joints and apical half ofthe last, which are piceous; joints 2 and 8 about as long as broad;joints 3 to 8 subequal in length but progressively stouter; joints 9and (especially) 10 transverse, little flattened; joint 11 oval, about aswide as long. Head finely and sparsely punctured. Pronotumabruptly and strongly convex, finely and sparsely punctured withcorrespondingly sparse pubescence ; raised margins moderately broadand much deflexed at the front angles ; hind angles right ; basal foveaevery deep, grossly punctiform ; basal sulcus shallow, marked by a rowof coarse punctures close to base of pronotum. Scutellum oval, trans-verse. Elytra highly but not abruptly convex, rather coarsely andsparsely punctured, pubescence sparse; umbones inflated, entirelyreddish yellow. The juxtasutural spot has vague outlines but isbroadest internally and triangularly narrowed toward (or to ?) theumbo. The postmedian bar is concave anteriorly, convex posteriorlyand extends from the lateral margin almost to the suture. Under sur-face, including legs and elytral epipleurae, pitchy red. The epipleuraeare coarsely punctured. Length 2.5 mm., width 1.5 mm. 388 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 93Type.?Male, U.S.N.M. No. 55886.Type locality.?Cuernos Mountains, Negros, P. I. (C. F. Baker).STENOTARSUS FLAVOSCAPULARIS, new speciesGenerally similar in markings to the preceding but easily dis-tinguished by the much shorter and very convex form and the stronglyshining elytra. Antennae half as long as body, first two joints pitchyred, remainder black except apical joint, which is reddish (probablyyellow in life) ; joints 2 to 7 subequal in length, joint 8 a little shorter,joints 9 and 10 broadly obconical; the outer-apical border of joint 11almost a semicircle, the inner border slightly convex; all three clubjoints very little flattened. Pronotum very much as in S. flavomacula-tus, black, shining, very finely and sparsely punctured, each puncturebearing a fine, erect seta. Elytra highly elevated, black, shining, finely,sparsely punctured and with correspondingly sparse, erect pubescence ; umbo moderately inflated, entirely gold-yellow. There is a broadbar of like color between the umbo and suture and another bar ofsimilar shape and color between the middle and apex of each elytron.Under surface and legs black; tarsi and coxae pitchy red. Length2 mm., width 1.25 mm.Type.?Male, U.S.N.M. No. 55887.Type locality.?-Dapitan, Mindanao, P. I. (C. F. Baker).Three specimens bearing the same data as the type are designatedparatypes. On one of these the anterior elytral spot is small androunded ; on another it is confluent with the light color of the umbo ; and on the third it is similar to that on the type, i. e., transverselyrectangular. A specimen from St. Thomas, Luzon, is very similar tothe type, while yet another, from Lamao, Luzon, has the elytra broadlyyellow at the base and the postmedian mark is a bar extending fromthe suture to the lateral margin. This last specimen may representstill another species, since in addition to the differences in markingsthe punctures of the pronotum and elytra are coarser. In its markingsand puncturation it resembles S. flavoinaculatus but is identical inshape with the type of S. flavoscapulaHs, and the difference in thisrespect is too great to admit the hypothesis of intergradation. Boththese species present striking divergences from other species of Steno-tarsus, but there are no characters worthy of generic recognition.Genus ANIDRYTUS GerstaeckerANIDRYTUS PARDALINUS, new speciesFigure 12, /, gSize large for the genus, strongly but evenly convex (section A ofGerstaecker) . General color deep rust-red. Antennae with five basal SOME ENDOMYCHID BEETLES?STROHECKER 389joints red ; joints 6 to 10 black ; joint 11 black, with its apical half red.The lateral sulci of the pronotum are shallow but sharply impressedand extend to the middle of the disk. Between these sulci and occu-pying most of this area is a pair of large, quadrate, black spots, nar-rowly separated from each other. On the elytra the basal third,including the humeri, black; internally this black area is continuedas a narrow stripe along the suture, broadening a little on its apicalthird, thence becoming evanescent. At the middle of each elytron thereis a large, rounded, black spot, laterally placed and behind this asimilar but considerably smaller spot. The entire upper surface isclothed with a short, declivent, coppery pubescence. The puncturingis everywhere fine and sparse except at the sides of the pronotum,where it becomes a little denser and coarser. The front tibia bears abroad, sharp tooth internally at its distal third. Another feature,probably sexual, is a densely pubescent area of semicircular shape atthe middle of the posterior margin of the first abdominal segment.Length 8' mm., width 4 mm.Type.?Male, U.S.N.M.

The insect before me meets all the genericrequirements proposed by Arrow for Parasymbius. He makes nomention of the prosternum, but the present species has the prosternumroundly carinate before the front coxae, flattened between them andmargined ; posteriorly it is prolonged beyond the coxae, its tip a little.deflexed and rounded. It differs from Arrow's species in its smallersize, greater length of antennal club, and sparser pubescence.Genus TROCHOIDEUS WestwoodTROCHOIDEUS COELO-ANTENNATUS, new speciesFigure 12, a-cSlenderer and less densely pubescent than T. ameiicanus Buquetand T. desjardinsi Guerin. Clypeus truncate anteriorly, the clypeo-frontal suture a broad, low arc. Front shallowly and broadly de-pressed on each side near the insertion of antennae. Ej^es prominentand coarsely granulate. Antennae relatively shorter than in thetwo species referred to above, massive; joint 1 bulbous, joint 2 verysmall, narrow at base and rapidly expanded to its apex, joints 3 and4 together forming a large bulb with nipplelike apex. There is nofifth joint apparent, On the under side these two joints are sodeeply concave as to appear hollow ; the margin of this concavity isauriculate. Mandibles with slender, aciculate apex. Labium, labialand maxillary palps as in T. desjardinsi. Pronotum almost twiceas wide as long, front angles rounded, sides broadened before themiddle, thence subsinuately narrowed to the slightly acute hind an-gles. The pronotum has a shallow, parabolic impression at the mid-dle of its base and a transverse impression on either side of this.Scutellum transverse, rounded behind. Umbones of elytra promi-nent but not inflated. Elytra evenly and moderately convex, gentlywidened in anterior third, thence evenly rounded to the apices, whichare subtruncate.

Identical withtype except for color and antennal structure. The antennae havethe first and second joints as in the male, joint 3 three times aslong as 2, as broad at its base as apex of joint 2, thence expanded toabout twice its basal diameter. Joint 4 is about as long as 3, broaden-ing toward its apex, which ends in a small nipplelike elevation. Infigure 12, c, the third antennal is considerably foreshortened. Thecolor of the allotype is darker and more uniform than that of thetype, and the sutural stripe is scarcely evident. I am inclined tothink that all the specimens are teneral and that the allotype morenearly represents the mature condition. Besides the type and allo-type the U. S.
