Mentum very narrow, very elongated, and fused with the ligular 
part which bears very long, ciliate hairs, but does not project 
beyond the basal joints of the labial palpi, the basal joints of the 
palpi are contiguous, set on the outer face, parallel and longer but 
not much wider than the second, apical one conspicuously ovate ; 
maxille long, club-shaped, rounded and slightly obliquely truncate at 
the top where the labial palpi are inserted, the upper and inner lobe 
are obliterated, but the inner part bears a few ciliz; maxillary palpi 
long, second joint broadly dilated at tip, cone-shaped, apical one sub- 
fusiform or nearly cylindrical and not acuminate; clypeus quadrate, 
separated from the frontal part by a high transverse keel, plainly 
marginate all round, laminate and projecting horizontally at the 
anterior part, labrum fused with it or at least without visible suture, 
quite vertical for some distance from the laminate projecting 
edge, and sharply aculeate; eyes very large, gene distinct and pro- 
longed into a canthus dividing the anterior part of the eyes, frontal 
part plane, strongly carinate laterally and without any transverse 
ledge on the vertex; antennze 10-jointed, the fourth joint is com- 
pressed and aculeate in the inner part, and the club consists of six 
very long lamellate joints; prothorax plainly diagonally attenuate 
laterally in the anterior part, but not in the posterior the angles of 
which are moderately rounded; scutellum ogival ; elytra parallel, 
faintly bi-striate on the dorsal part, but with the juxta-sutural stria 
plain, they have a thick fringe of very long hairs along the outer 
margins, and cover the greatest part of the propygidium; pygidium 
sub-vertical, acutely triangular, but truncate at the apex; anterior 
tibiae bi-dentate, intermediate and posterior ones with an interrupted 
ciliate carina dilated at apex; intermediate and hind tarsi very 
long, especially the latter, and beset with very long hairs; hind 
spurs not sharp at apex, but not compressed, and strongly divari- 
cating ; claws long, slender, with the posterior half a little wider 
than the anterior, the widened part ending in a very short vertical 
tooth.
