 and continuous with the sides; widest one-third from base, broadly flat- 

 tened near hind angles, which are obtuse: surface coarsely and densely 

 punctate, faintly impressed each side near base. Elytra equal in width to 

 thorax, sides parallel in basal two-thirds; surface with feebly impressed 

 rows of rather small punctures; intervals linely and sparsely punctate.
