Among our few species with dull, aciculated thorax this one is the

Black; the thorax dull with feeble silky lustre, but the bosses on

The body rather flat and broad; head, pronotum and elytra densely 

 and finely longitudinal aciculated without distinctly separated punc-

 pronotum, anteriorly flat, the vertex most often with short middle- 

 groove, sides inside the eyes very finely margined, eyes rather small, 

 antennae short, rather strongly thickened distally; pronotum a little
