Body narrow, clotbed fairly densely above (clypeus excepted) witb long narrow 

 adpressed scales. 



Mentum (PI. 12, fig. 7) about | as broad as long, suboblong, towards tbe base ratber 

 broader witb sides rounded, not sbarply constricted but witb tbe sides only sinuate at tbe 

 point of insertion of tbe palps, tbe front margin sinuate but not sbarply emarginate in tbe 

 middle, tbe anterior angles rounded and bearing bairs : apical joint of labial palpi about 

 twice as long as tbe second. Maxillre (PI. 12, fig. 6) witb tbe upper lobe not very robust, 

 a subquadrate plate with two tooth-like projections at its upper and inner angle : apical joint 

 of maxillary palpi swollen and fusiform, nearly as long as tbe second and third together. 

 Mandibles (PI. 12, fig. 5) with a strongly-chitinised apical tooth and a delicate inner mem- 

 branaceous portion. Labrum (PI. 12, fig. 4) almost horizontal, broad and short, with the 

 front margin slightly sinuate medially. Antennae 9-jointed, 6th joint very short ; tbe club 

 (joints 7 — 9) as long as joints 2 — 6 taken together, tbe lamellae of joints 7 and 9 convex 

 outwardly, when closed almost concealing the slightly shorter middle lamella (joint 8). 

 Clypeus short and somewhat broad, with its anterior margin nearly straight, not emarginate, 

 reflexed, the angles rounded off; its surface slightly concave, with only few very small hairs, 

 devoid of the conspicuous scaly covering of the rest of the head and body. Protborax 

 broader than long, strongly narrowed in front, produced in the middle of the base into an 

 angle (covering tbe base of the scutellum). Scutellum very small, ovate, with apex angular. 

 Elytra slightly narrowed behind the middle, separately rounded at the apex. Pygidium 

 vertical, ventral abdominal segments not contracted in either sex. Middle and posterior 

 coxae contiguous, the posterior transverse and projecting slightly at tbe sides of the abdomen. 

 Anterior tibiae bidentate, the proximal tooth very little developed, the apical one well- 

 developed and oblique : apical spur absent. The middle and posterior tibiae have each 

 a single apical spur about as long as the first tarsal joint : posterior tibiae somewhat 

 broader than the middle ones, but not greatly swollen or thickened as in some genera. 



In the $ all the tarsi have 2 claws, both of which are cleft at the apex, the larger one 

 specially broad and flattened (PL 12, fig. 8). I have only seen one ?, from which the
