 oped, moderately prominent; punctures rather coarse and close -set 

 in basal half, the anterior half almost impunctate; prothorax distinctly 

 elongate, as long as the head and slightly wider, the sides parallel and 

 evenly, very distinctly arcuate, the punctures moderate in size, unusually 

 feebly impressed and not at all conspicuous, sparse; elytra distinctly 

 elongate, parallel, only very slightly longer but more distinctly wider 

 than the prothorax, the punctures small but strong, close-set and con- 

 fused throughout; abdomen as wide as the elytra, gradually tapering 

 posteriorly, finely and not very closely punctate, polished. Male un-
