preceding species. They differ from it, however, in being 

 more convex (both sexes), the males with the projection 

 at the inner base of each mandible larger and more ob- 

 tuse, the tips somewhat different, the distance across the 

 eyes actually the widest part of the head, instead of with 

 projecting lobes in front of and behind same. They also 

 are quite black and shining, although without the 

 enamelled appearance of menalcas, so that altogether 

 their general appearance is strikingly different. The 

 female differs from the female of that species in the head 

 having somewhat sparser punctures, eyes more promi- 

 nent, each mandible with its tooth rather nearer the apex, 

 and not quite so acute, prothorax slightly longer in pro- 

 portion, and elytra with somewhat sparser punctures. 



Each mandible' could scarcely be regarded as having 

 a cuspidate mass, as the subapical cusp is the only dis- 

 tinct one, and this is so close to the apex that the apex 

 itself appears bicuspidate or notched. Some of the 

 punctures on the front of the prothorax. but not in the 

 middle, are larger than any on the head. There are 

 usually six strong teeth on the front tibise.

^lale. Black, subopaque; sides setose. 



Head Vvide, moderately convex, scarcely or not at all 

 concave in middle of apex: sides slightly projecting be- 

 hind eyes, and feebly or not at all in front of same. With 

 dense, large, round punctures at sides, becoming smaller 

 and sparser elsewhere, and sometimes absent from cer- 

 tain parts. Labrum strongly but obtusely produced in 

 middle. Mandibles usually rather slender, each with a 

 strong projection close to labrum: upper surface with 

 two projections beyond the middle, lower usually with a 

 strong cusp near apex, and a very small one behind it. 

 Prothorax slightly wider than head, sides feebly serrated 

 and gently rounded, becoming oblique or very feebly in- 

 curved towards base; apex feebly rounded m middle; 

 flattened or very feebly depressed along middle; with 

 dense coarse and irregularly distributed punctures, but 

 along each side of middle smooth and with very minute 

 punctures only. Elytra with feebly projecting shoulders;
