Abdomen beneath obsoletely granulose, rather densely, finely punc- 

 tate, the punctures connected transversely by fine, sinuate lines, 

 which are coarser on the basal segment, sparsely clothed with short, 

 recumbent, white hairs, with a more densely pubescent spot at the 

 sides of the third, fourth, and fifth segments; first and second seg- 

 ments convex at middle; last segment broadly rounded at apex; 

 vertical portions of first and second segments densely pubescent; 

 pygidium feebly carinate, but the carina not projecting. Pres-

 long, recumbent, whitish pubescence; prosternal lobe broad, moder- 

 ately declivous, and broadly, vaguely emarginate or subtruncate in 

 front; prosternal process broad, the sides slightly expanded behind 

 the coxal cavities, and truncate at apex. Tibiae slender, anterior 

 pair slightly arcuate, and all pairs without a tooth at apex. Pos- 

 terior tarsi slightly shorter than tibiae, and the first joint as long as 

 the following two joints united. Tarsal claws similar on all feet, 

 cleft near the middle, the inner tooth broad, shorter than outer one, 

 and not turned inward.
