AMERICAN COMPONENTS OF THE TENTYRIIN^ 42 1 



punctured, the epistoma broadly rounded, the lateral lobes small, 

 strongly rounded ; prothorax large, one-half wider than long, the 

 apex barely two-thirds as wide as the base, transverse, with the 

 angles gradually projecting anteriorly, prominent and acute but 

 not blunt or narrowly prolonged, the sides almost straight and 

 feebly converging from the right and unrounded basal angles for 

 more than half the length, then broadly, rather strongly rounding 

 and converging to the apical angles, the surface very obsoletely 

 impressed near each side of the base, evenly and strongly convex, 

 very finely and sparsely punctate, the punctures but little larger 

 and still sparse laterally and more crowded along the sides ; scutel- 

 lum as long as wide, ogival, hairy ; elytra rather abruptly and 

 strongly, arcuately narrowed behind to the obtusely ogival tip, the 

 sides parallel and broadly, evenly arcuate to the obtuse humeri, 

 which are not evidently exposed at base and with the callus small 

 but distinct, the surface smooth, without impressed lines even 

 apically, very finely punctate, somewhat closely so laterally and 

 in broad alternately closer and sparser longitudinal lines thence to 

 the suture ; abdomen more densely pubescent laterally, finely 

 and strongly, rather closely punctate and shining medially. 

 Length 9.4 mm.; width 4.4 mm. Texas (Marfa), — H. F.

Epitragodes Csy. 

 This is one of the few Epitragid genera peculiar to the Carib- 

 bean faunal province. It is composed of moderate or small, 

 oval and convex species, having coarse and conspicuous decum- 

 bent and irregularly disposed pale pubescence and the elytra 

 gradually narrowed posteriorly to the notably acute apex. The 

 genus is distinctly intermediate between the preceding genera, 

 with a deep mesosternal excavation receiving the prosternum, 

 and those which follow, having no prosternal projection or meso- 

 sternal impression, for here the prosternum is narrowly and 

 briefly produced posteriorly behind the coxae and the meso- 

 sternum is tumid and with a more or less feeble concavity, not 

 however receiving the prosternum, which never attains the im- 

 pression, these characters being plainly degradational or vestig- 

 ial in nature. The mandibles are rapidly narrowed and polished 

 toward their truncate apices, deeply excavated beneath toward 

 base or strongly arcuate along the external line, and have the 

 tooth of the right mandible, clasping the labrum, unusually 

 developed, the left mandible tumid above and sometimes sub-
