angles depressed, the sides submarginate ; the surface equate (with an 

 obsolete thread-like fovea at the base), finely and thickly punctured, 

 and clothed throughout with a short downy pubescence. Scutellum 

 triangular, dark fuscous. Elytra oblong, subelongated at the apex, 

 very finely punctate-striate, of a somewhat deeper colour than the

 tracted in front, and in the character of the punctuation of the elytra.
