 little more convex, and the elytra a little more ovate ; the prothorax 

 is deeply punctured all over, the punctures being, however, widely 

 separated, and the shape of the clypeus and genae is quite 

 different.

 rately deep and punctulate, intervals plane and having each two 

 series of setigerous scabrose punctures, second interval very little
