carina and a basal one connected laterally by the ocular ridges, and 

 having a short, sharp tubercle on the frontal carina ; anterior femora 

 moderately thick and armed with a sharp median tooth on the lower 

 margin ; anterior tibiae quadri-dentate outwardly, strongly falcate at 

 tip, with the mucro very long, underneath there is a carina pro- 

 duced at middle into a broad, triangular sub-obtuse vertical tooth ; 

 trochanters of intermediate and posterior legs sharply spinose, inter- 

 mediate femora deeply emarginate from the median part, armed with 

 a sharp spine and having the apical part of the emargination sub- 

 dentate, intermediate tibiae produced inwardly into a large, quadrate 

 lamina at apex ; posterior femora with a broad, sharp, horizontal, 

 moderately broad spine, posterior tibiae slender for one-third of the 

 length and dilated from there. 



Female : Differs from the male merely by the shape of the clypeus, 

 which is more elongate and therefore more sharply triangular ; the 

 frontal carina is hardly discernible, and the tubercle is identical ; the 

 legs are, of course, simple. 



Length 16i-18J mm. ; width 10-11 mm.

Mentum short, nearly twice as broad as long, very deeply excavate 

 in the central part, and deeply and widely emarginate at tip ; labial 

 palpi as in Onitis, but the second joint is much more elongate and 

 narrower (fig. 29) ; the maxillary palpi are nearly similar, but the 

 third joint is longer and slightly curved, and the apical one is 

 more fusiform, but not attenuate at base, and has a slight, short, 

 impressed line outwardly ; the maxillae are a little more slender than 

 in Onitis, and the lobes are similar ; antennae nine-jointed, first joint 

 of the clava cupuliforni ; head pentagonal, genae projecting ; prothorax 

 dehiscent or vertical at apex, with the disk somewhat plane and the 

 sides declivous, ampliate laterally at middle and foveolate on each 

 side, base nearly straight, slightly sinuate at middle, but not pro- 

 jecting, and distinctly bi-impressed on each side of the median part ; 

 scutellum wide, sharply triangular at tip ; elytra somewhat plane, as 

 broad as the base of the prothorax, deeply sinuate laterally at a short 

 distance from the humeral angle, declivous at apex and sub-callose 

 outwardly ; they have nine geminate striae, the epipleuras are very
