Elytra slightly wider than pronotum at base, about equal in width 

 at base and just behind the middle, feebly, broadly, arcuately con- 

 stricted in front of middle, and narrowed from near the middle to 

 the tips, which are separately, broadly rounded, and coarsely serrate ; 

 sides of abdomen narrowly exposed above; disk slightly flattened, 

 with vague longitudinal costae, sutural margins slightly elevated pos- 

 teriorly, and with broad, deep basal depressions; surface densely, 

 coarsely granulate-punctate, and clothed with inconspicuous pu- 

 bescence at apex. 



Abdomen beneath finely, densely punctate, becoming densely iiabri- 

 cate-punctate on basal segment, and rather densely, uniformly clothed 

 with short, recumbent, whitish pubescence; first segment broadly, 

 feebly concave, the second with a deep, smooth groove at the middle, 

 which extends from the anterior margin to behind middle of seg- 

 ment ; vertical portions of segments not conspicuously pubescent ; 

 pygidium coarsely punctate, with the median carina strongly ele- 

 vated, narrow, strongly projecting, and truncate at apex. Pro- 

 sternum coarsely, densely punctate, somewhat rugose posteriorly, and 

 sparsely clothed with short, semierect, whitish hairs; prosternal lobe 

 rather narrow, strongly declivous, and subtruncate or vaguely emar- 

 ginate in front; prosternal process broad, the sides parallel to be- 

 hind the coxal cavities, then abruptly narrowed to the apex, which is 

 acute. Posterior coxae with the posterior margin transversely sinu- 

 ate, and the exterior angle nearly rectangular. Tibiae slender, feebly 

 arcuate, and all three pairs armed with a small tooth on the inner 

 margin at apex. Posterior tarsi slightly shorter than the tibiae, and 

 the first joint slightly longer than the following two joints united. 

 Tarsal claws similar on all feet, cleft near the middle, the outer tooth 

 acute at apex, the inner one broader, slightly shorter, turned inward, 

 and the tip nearly touching that of the opposite side. 



Length. 8 mm. ; width, 2.25 mm. 



Female.— Differs from the male in having the front of head 

 slightly wider, the surface more coarsely punctate and less densely 

 pubescent: tibiae unarmed at apex; posterior tarsi shorter; pro- 

 sternum more sparsely punctured, and the second abdominal seg- 

 ment not grooved at the middle.
