INH.VBITING NORTH AMERICA. 79 



lateral ed^e reflected, dorsal line conspicuous, posterior 



angles acute. 

 Elytra profoundly striated, stri;e punctured on the sides, in- 



terstitial lines convex. 

 Pectus and postpedus with obsolete dilatetl punctures ; feel 



testaceous; venter piceous towards the tip, iiupunttured. 



In this species the eniargina of the anterior tibia is very 

 small and placed vtu-y near to the tip, so as to he undisco- 

 verable but by particular examination. Ju(li!;in2; from the 

 geneiic deOnition whicli authors have c;ivcn. liiis species 

 must ditter from the other species of this genus in tiie form 

 of the labium, which is elonu;atcd, acute, as in I'ni^onophorus, 

 and has on each side near the tip a lomi; hair or bristle, in- 

 stead of spines, as in the latter genus: it does not tiierefore 

 agree witli tlie character given of the labium of J^ehria, — 

 "labium subquadrate," "labium short," " nearly quadrate," 

 ^c, nor yet witli that of Pogotiophoriis, of wiiich tliis part is 

 tricuspidate. But as it will not agree with any other than the 

 two genera above mentioned, and as it difters from the lat- 

 ter genus in not having the mandibles dilated at base, nor the 

 maxillary palpi mucli elongated, I have thougiit proper to 

 place it with the present genus, to which it seems to have the 

 closest afllnity.

 the exterior side ; body short, nearly Iiemis|)hcrical ; tho- 

 rax trapezoidal, transverse, sinuatcd, or lol)ed behind ;
