 than wide: sides nearly straight, feebly curved on apical third; disk mod- 

 erately convex, rather densely and finely punctured; hind angles obtuse, 

 slightly excurved and divergent, not carinate. Elytra with sides nearly 

 parallel to apical third, thence converging to the acute tips; stria 1 feebly 

 impressed, punctate ; intervals subconvex, densely punctulate. Length 10.5-
