passing beyond the base of the pronotura ; first segment elongate, 

 thickened and club-shaped, second also elongate and club-shaped,

 the sixth to the eleventh much thickened and covered with 

 brownish hairs. Prothorax narrowed in front, broader than long, 

 front edge emarginate, base almost straight on either side of the 

 scutellum, sides almost straight or very gently rounded from base 

 to anterior angles, which are rounded, the posterior ones being 

 almost right angles ; upper surface convex from side to side, the 

 sides covered with large, coarse and confluent punctures, and the

impunctate. Elytra slightly broadened behind ; their whole sur- 

 face is confusedly and strongly punctate, without any trace of

 genus; along the margin there is a narrow impunctate strip. 

 Underside more shining than the upper side; abdominal sternites 

 more or less sparsely punctate, other parts also bearing punctures, 

 sometimes coarser. Apices of tibiae externally ending in a spine, 

 excavated for the reception of the first segment of the tarsus ; 

 underside of femora channelled; claws with an appendix on the 

 underside.
