 from base to the subapical constriction; disc finely, evenly, deeply not 

 densely punctate, with a small smooth spot at middle. Elytra oval, one-third 

 wider and two and a half times longer than thorax, humeri oblique; disc 

 finely striate, the strial punctures small, deep, elongate, remote; inter- 

 vals equal, strongly convex, each with a row of small punctures. Abdomen

 beak shorter than thorax, nearly straight, finely punctured ; an- 

 tenna? inserted one-third from its tip ; scape scarcely reaching 

 the eyes, funicle short, first joint longer and stouter, the others 

 subnioniliform, closely united ; head inserted in thorax beyond the

 ernarginate in front, its pectoral groove deep ; first ventral slightly

 Beaten from dead branches of beech. Recorded from Pennsyl- 

 vania, Ohio, District of Columbia and Georgia. Easily known 

 by its small size, brown color and numerous prominent bristles, 

 which are all erect in the specimens in hand, not reclinate on 

 the elytra as stated by LeConte.
