 margin of the elytra in the male shining black, becoming paler towards 

 the apex of the latter, in the female piceous, gradually fading into

 greenish yellow. Hind tibiae greenish glaucous, infuscated apically. 

 Hind femora with the knees of male infuscated externally, internally

 with a longitudinal black patch. Antennae basally testaceous to 

 ferruginous, becoming infuscated on apical half.

122. Paracornops dorsatum sp. nov. 



Quite similar in color and general appearance to P. longipenne, or 

 the insect that has been determined as that species, but smaller and 

 decidedly slenderer. Prosternal spine transverse at base, evenly and 

 quite abruptly tapering to the acuminate apex, which is directed 

 gently towards the front. 



Head of moderate size, no wider than the front edge of the pronotum; 

 face and cheeks below the eyes profusely, but not very coarsely, 

 punctulate. Eyes subglobose, not prominent, slightly longer than 

 the anterior edge of the cheeks immediately below them, their hind 

 margins forming nearly a right angle, separated at the vertex by a 

 space slightly greater than the widest portion of the frontal costa; 

 fastigium of the vertex about as long as wide, shallowly sulcate at 

 middle anteriad, the raised margins meeting in a right angle. Frontal 

 costa not prominent, of nearly equal width throughout, punctulate 

 and shallowly sulcate from between the antennae almost to the clypeus, 

 where the lateral carinae become obsolete. Facial carinae divergent, 

 straight, fairly prominent. Antennae filiform, a little longer than the 

 head and pronotum combined. Pronotum subcylindrical, rather 

 closely and granularly punctulate, the hind lobe a little expanding, 

 its posterior extremity obtusangulate; median carina visible through- 

 out, severed only by the last transverse sulcus, which is inconspicuous
