Mentum fused with the ligular part, deeply impressed on the 
outer face, bulging laterally and with the ligular part transverse, 
not emarginate, but with the angles rounded, last joint of labial 
palpi longer than the two preceding, slightly curved, sub-cylindrical, 
but somewhat acuminate towards the tip; mavxille robust, hollowed 
on the inner face, provided with two strongly bifid teeth, diverging, 
but set on the same line, and an angular one beneath these two, the 
latter has a small bunch of hairs and represents evidently the inner 
lobe of the maxille ; maxillary palpi moderately long, last joint very 
swollen outwardly, almost clavate, and somewhat deeply impressed, 
straight inwardly ; mandibles robust, but compressed and chisel- 
like at the tip; labrum vertical, deeply emarginate; clypeus 
narrower than the head and separated from it by a somewhat 
indistinct, transverse impressed line, eyes large, divided in front by 
a slightly hairy canthus, head without any transverse frontal ridge ;

moderately elongate and longer in the male, ovate in the female, 
the first joint is longer than third-sixth, the sixth is sharply 
laminate in the male, less so in the female; prothorax ampliated 
laterally in the middle and nearly equally attenuate thence towards 
the base as towards the apex, outer margins slightly reflexed, basal 
angle sharp, anterior margin slightly pubescent near the angles in 
the male, but all along the length in the female; scutellum some- 
what short, ogival, one-fourth broader than long; elytra hardly 
wider at the shoulders than the basal part of the prothorax, slightly 
sinuate below the humeral part and thence moderately ampliate 
towards the posterior, moderately convex, retuse behind and 
covering nearly the whole of the propygidium; propygidium sub- 
vertical but convex in both sexes; abdominal segments fused ; 
anterior tibie strongly tri-dentate outwardly and with a long inner 
spur, tarsi moderately long, claws moderately robust, long, and
