116 HOMAMMATUS. 



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 

 thorax ; clothed throughout with a close, short, flavous pubescence. 

 Antennce filiform, black. Legs pale testaceous, with the anterior 

 tibiae and tarsi (and the base of the posterior femorli) fuscous, and 

 the posterior tibiaB and tarsi rufo-fuscous. 



This species abundantly differs from P. olivaceus in its colour (fla- 

 vous, instead of olive-green), in the form of its thorax, which is not con- 

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