somewhat narrowed anterior angles of the thorax, rather shining propygidium, less 
transverse pygidium, and tibie less dilated and more angulated. One example.

Two specimens. This remarkable insect agrees in some of its characters with 
Homalopygus; but in others it resembles Plegaderus, especially in the shape of the 
thorax and prosternal lobe.
