PiTYOBIUS BlLIilNGSII. U. sp. 



Blackish-piceous ; antennae pale brown ; legs and abdomen pieeous. 



//«i.— Canada West. (Coll. Ent. Soc. Philadelphia.) 



% . Body blackish-piceous; head coarsely and confluently punctured, 

 deeply excavated between the eyes ; mouth pieeous ; antennae longer 

 than the head and thorax, bipectinate, brown, becoming paler toward 

 the tip, ord joint broader and larger than the 2nd. Thorax black, 

 about equal in length and breadth, coarsely and confluently punctured, 

 sides rounded in front, somewhat sinuate behind the middle, the pos- 

 terior angles long, subacute, cariuated and strongly divergent ; dorsal 

 groove deep, broader just behind the middle, on each side of this 

 groove in front there is a large deep depression ; posterior margin 

 strongly and transversely depressed on each side. Elytra elongate, 

 subconvex, slightly depressed at the anterior fourth, .aides almost paral- 

 lel, being slightly sinuate about the middle, gradually rounded at tip ; 

 striae deep, not distinctly punctured, interstices convex, rugosely punc- 

 tured; abdomen beneath pieeous, finely punctured. Legs pieeous, va- 

 ried with rufous, tarsi pale rufous. Length 12 J lines. 



This species differs from the % specimen before me of P. a Hiyainus 

 Lee, by being much more robust, more coarsely punctured, the depres- 

 sions of the thorax, though similarly situated, are much deeper and 

 larger, the striae of the elytra are more deeply impressed and the in- 

 terstices more coarsely punctured. The greatest difi"erence between 

 these two species, however, lies in the proportions of the thorax, which 

 in the present species, is as broad as long and the sides rounded in 

 front, while in anguinus it is longer than broad and the sides nearly 

 parallel. The color of the antenna) and legs is also dififerent. 



It gives me pleasure to dedicate this fine species to Mr. B. Billings. 

 Jr., of Ottawa, Canada West, to whose kindness the Society is indebted 

 for this and many other valuable Coleoptera.
