 about the middle of the elytra ; first segment long and club- 

 shaped, second shorter and much thicker than the third, which 

 is slightly longer than, the fourth, the following three equal, 

 the last four more thickened. Prothorax broader than long, sides 

 straight, anterior lateral angles truncate; surface granulate- and 

 sparsely punctate. Scutellum triangular with apex, rounded and 

 surface linely granulate. Elytra hardly broader at base than 

 prothorax, humerus prominently convex; surface confusedly

Head iin punctate, frontal tubercles not well developed, area all 

 round the bases of the antennae excavated. Antennae nearly as

 thickened but smaller, third and the two following segments 

 nearly equal to each other, smaller and thinner than second, sixth 

 neither much thickened nor as thin as fifth, the following seg- 

 ments thicker. Prothorax much broader than long, sides slightly 

 rounded, anterior lateral angles oblique ; surface not very closely 

 and finely punctate, the interstices extremely finely granulate. 

 Scutellum triangular, broader than long, with the surface granulate. 

 Elytra distinctly widened at the middle, rather convex, the 

 shoulders rounded ; closely and very strongly punctate, the inter-
