The pronotum is transverse. The anterior margin is practically straight, the sides 

 lightly and the posterior margin more distinctly convex. The scars are a little uneven, but 

 are not definitely punctured. The prosternum is pointed behind. 



The scutellum is smooth or distinctly but sparsely punctured. In the specimen in which 

 the scutellum is unpunctured there is a strongly marked median groove ; in the other this 

 groove is much broken. The mesothoracic episterna are glossy and coarsely punctured all 

 over, except in the posterior angles, which are matt and have less distinct or no punctures 

 but may be more or less rugose. The mesosternum is more or less smooth and glossy all 

 over — less so at the sides than in the middle.

The lateral areas of the metasternum are narrow. These, the anterior intermediate 

 areas, and the outer margins of the posterior intermediate areas are punctured and hairy. 

 The rest of the plate is smooth, hairless and glossy, as are also the posterior coxae and 

 the abdominal sterna. The grooves of the elytra are somewhat strongly punctured, 

 especially laterally, but the punctures are small and round. The middle and hind tibiae 

 are without spines except at the apex.
