 yellowish pubescence, the legs thickly studded with erect pale 

 yellow hairs, the tibial calcaria pale yellow, the tibiae above with a 

 double row of short reddish-brown spines. Head small, about as 

 broad as the thorax closely punctured somewhat lenticular, three 

 times as broad as long, the front faintly convex, the occiput arched ; 

 mandibles acutely pointed with a short blunt tooth on their inner 

 margins, antennae opaque, antennal tubercles rounded, not prominent 

 2nd joint of the flagellum about a third longer than the 3rd or 4th 

 joints; eyes large prominent, their lower orbits closer to the bases of 

 the mandibles than their upper orbits to the occiput; head behind 

 the eyes not much developed, rounded. Thorax from above rect- 

 angular dorsally longitudinally deeply carinate striate, the pronotum 

 arched in front, the humeral angles rounded, median segment 

 posteriorly vertically truncate, its posterior face vertically carinate, 

 the apical margin above toothed, the teeth, which are continuations 

 of the irregular longitudinal carinae covering the dorsal surface 

 of the thorax, short. Abdomen massive above closely punctured, 

 beneath : the bases of segments 2 to 6 very finely transversely striate, 

 their apices punctured, ventral carina of basal segment very slightly 

 raised twice incised, pygidial area well defined, slightly convex, 

 longitudinally striate.

 legs with shorter similar yellowish hairs ; the apical margins of the 

 1st and 3rd abdominal segments each with a broad transverse band 

 of golden pubescence, the apical margin of the 2nd segment with a 

 narrow fringe of the same pubescence, beneath which the segment is

 finely punctured ; eyes large slightly convex, their upper orbits as 

 far from the posterior angle of the occiput as their lower orbits from 

 the base of the mandibles ; mandibles acute at apex, simple ; 2nd 

 and 3rd joints of the antennae subequal. Thorax closely punctured, 

 the punctures running into longitudinal striae, wider anteriorly than 

 posteriorly, the apex roundly truncate ; legs robust, the intermediate
