from the base ; third joint straight. Thorax cylindrical, sides 
without tubercles, surface punctured. Elytra linear, apex

This genus forms a portion of a small group — including Dor- 
casta, Aprosopus, and Spalacopsis (= Eutheia, Guer.) — which 
differs from all the foregoing in the form of the head and in the 
shortness of the antenniferous tubercles.
