 slightly prominent, occupying two-thirds of the sides; anterior part 

 not distinctly flattened; with scattered punctures except on vertex, 

 punctures indistinctly umbilicate; with fine but distinct scaly ground 

 sculpture interspersed with fine piinctulae. Pronotum scarcely longer 

 than wide, widest at anterior third, moderately narrowed to anterior 

 angles, sinuately narrowed to strongly rounded base; with two in- 

 definite series of large punctui-es along midline, of eight to nine 

 punctures, with a lateral series of seven or eight and scattered addi- 

 tional punctures; ground sculpture finer than on head ; vestiture nearly 

 absent. Elytra conjointly widely emarginate, outer angles not evenly 

 rounded ; den.sely and coarsely punctate, but without distinct ground 

 sculpture. Abdomen with sternites 3 to 5 with an angulate basal ele-
