 margined, nearly straight and converging a little anteriorly, hind 

 angles sharply defined, front angles scarcely defined; surface rather 

 densely punctured but not distinctly granulate, Avith a well-defined 

 transverse median impression. Elytra about twice as long as wide, 

 distinctly Avidcr at the posterior third, punctures rather fine and 

 dense. Prosternum rather long before the coxae. Middle coxae con-

This species is very closely allied to E. trapezoideus Fall, but is 

 distinguished from that species by being entirely black, with the 

 exception of the tibiae and tarsi in both sexes, by the head across 

 the eyes not being wider than the prothorax, smaller eyes, and by 

 the different arrangement of the antennal joints.
