wider, oval, widest though only a little more rounded at the sides behind 

 basal third ; humeri evident at base ; humeral plica narrow and strong, the 

 impression deep and oblique ; inner fovea large and very deep ; subsutural 

 impressions very feeble, the suture very slightly elevated toward base. Dorsal 

 pygidium with the mere tip exposed and broadly rounded. Legs long ; femora 

 moderately clavate, the posterior feebly; tarsi long and slender. Length 1.3 

 mm.; width 0.6-0.65 mm. 



Pennsylvania (Westmoreland Co.). Mr. Schmitt. 



The type described above appears to be a male, but I can find 

 no obvious secondarj'- sexual structures and the abdominal apex 

 is but little modified. In the female the elytra are somewhat more 

 briefly oval and more inflated, and the antennae are slightly 

 shorter. 



The long, erect and \ery conspicuous pubescence of the elytra, 

 black color and transversely impressed head, will readily identify 

 pubipennis among the species of Brachycepsis. 



15. S. ventricillus n. sp. — Strongly ventricose, polished, impunctate, 

 except the elytra, which are minutely, very feebly and sparsely punctate ; 

 body deep black throughout, the abdomen slightly paler at tip ; legs and an- 

 tennae pale ; pubescence rather sparse, even, less distinct anteriorly, pale and 

 recurved on the elytra. Head transverse, the eyes rather small and bxit slightly 

 convex, a little longer than the tempora, which are nearly as prominent and 

 strongly rounded to the neck ; vertex with a deep transverse median impres- 

 sion, which is bisetose at the bottom ; fourth palpal joint only slightly more 

 than }^ as long as the preceding, finely aciculate ; clypeus large. Antennas as 

 long as the head and prothorax, gradually and strongly incrassate toward tip ; 

 second joint nearly as large as the first, % longer than wide, about as long as 

 the next two and very much stouter ; three to ten increasing gradually in 

 width, at first very slowly then more rapidly ; three and six scarcely as long 

 as wide ; fifth quadrate ; fourth }4' longer than wide ; seventh globular ; 

 eighth }-^, ninth %, and tenth % wider than long ; eleventh small, scarcely as 

 wide as the tenth and % longer, gradually ogival and oblique from the base. 

 Prothorax well developed, about as long as wide, almost % wider than the 

 head, subglobular, narrowed, rectilinear and finely carinate at the sides to- 

 ward base ; six basal fovese large and distinct, not united, the two lateral 

 near the carina ; flanks beneath the carina obliquely impressed. Scutellum 

 very small, equilatero-triangular. Elytra oval, very convex, }'^ longer than 

 wide, scarcely 2}4 times longer than the prothorax and % wider-; sides par- 

 allel and very evenly arcuate throughout ; humeri altogether obsolete ; sub- 

 humeral impression small but elongate and deep, the plica narrow ; outer 

 fovea obsolete, the inner deep and within a conspicuous subelongate excava- 

 tion ; suture not modified. Legs slender, the femora feebly clavate, the an- 

 terior more strongly; tarsi rather shor^. Length 1.1 mm; width 0.52 mm.
