 part is corneous and bears at tip two stronger and stiffer claw- 

 like ciliye and a small sharp tooth underneath ; apical joint of 

 maxillary palpi long, sub-cylindrical and truncate at tip ; antennae 

 ten-jointed, club tri-jointed, first joint larger than the other two and 

 concave, apical joint flat ; eyes deeply divided by the canthus of the 

 genae and showing much less on the upper than on the under side ; 

 mandibles partly hidden by the labrum, arciiate in the anterior part 

 where they are reflexed, slightly bifid at tip and ciliate laterally ; 

 head simple, labrum briefly transverse, emarginate at middle and 

 rounded laterally ; prothorax attenuate diagonally from base to apex 

 and with the anterior angles sharp and the basal one obtusely 

 rounded, very little convex on the disk and depressed laterally 

 behind ; scutellum sharply triangular ; elytra elongate, ampliate in 

 the posterior part, moderately convex in front, distinctly more so 

 behind, covering the pygidium, and somewhat indistinctly striate ; 

 coxae contiguous ; legs moderately slender ; anterior tibiae nearly 

 straight, not obliquely truncate and with a slender apical spur in the 

 outer angle, bi-dentate externally and strongly serrate above the digits 

 right to the base; intermediate and posterior tibias slender, bi-carinate, 

 ciliate on the upper side and not dilated at tip ; tarsi not quite as 

 long as the tibiae ; outer claws of the anteiior tarsi a little longer 

 than the inner one and having a small but sharp tooth underneath 

 towards the middle, intermediate, and posterior claws simple and of
