 bispinosus ; abdomen sessile, subtiliter punctatum, fere ellipticura, 

 thorace non longius ; femora postica subtus subaugulata ; alae nigri- 

 cantes, basi cinereae.

 roughly punctured. Prothorax large, subquadrate. Sutures of the 

 parapsides well defined ; tegulae testaceous ; scutellum armed at the 

 tip with a stout obtuse spine. Metathorax with two obtuse shorter 

 spines. Abdomen shining, thick, sessile, finely punctured, nearly 

 elliptical, acute at the tip, not longer than the thorax. Legs pilose. 

 Hind femora incrassated ; edge beneath dilated aud slightly angular 

 near the tip. Wings blackish, cinereous towards the base ; veins
