mentum and gense very strongly and abruptly raised from guhu. 

 Antennae stout; four basal joints cylindrical, six succeeding ones 

 compressed, apical joint elongate, oval. Prothorax very little 

 w ider than head (G - G x 7*5 mm.), convex, lightly declivous to base; 

 basal area defined b} T a transverse impression; sides subparallel, 

 rounded at posterior angles, hardly sinuate on each side of base; 

 anterior margin truncate; anterior angles widely rounded and 

 hardly at all advanced; base wide, rounded; border narrow, more 

 strongly retlexed behind posterior angles, thick on base; lateral 

 marginal channel narrow, not continued across base; a distinct 

 wide shallow impression in front of each basal angle; median line 

 linear, deep (only the anterior marginal puncture present in 

 specimen before me). Elytra about same width as prothorax 

 (15 x 7"7 mm.), very little rounded on sides; apical curve wide, 

 short, base truncate, vertical above peduncle; disc subdepressed; 

 sides and apex roundly and strongly declivous; border narrow, 

 thickened towards apex (the edge not retlexed on apical curve), 

 decidedly thickened and upturned (not dentate) at humeral 

 angles; four ocellate punctures in a slight depression on base near 

 each humeral angle, a fifth puncture at a little distance from 

 these; lateral row of punctures rather widely placed, except near 

 humeral angles. Suture between second and third ventral 

 segments entire; second ventral segment with a shallow concave 

 impression in middle between posterior trochanters; retlexed 

 border of apical ventral segment not foveolate on each side of 

 anus. Legs long; anterior femora thick, not dilatate in middle 

 or with a notch on lower side before apex, unipunctate near lower 

 margin of inner side towards apex : anterior tibia? bidentate, 

 apical plate without a dentiform projection below tarsus; inter- 

 mediate tibise with a strong triangular external tooth at apex; 

 posterior legs long, light, trochanters pyriform, triangular and 

 pointed at apex. Length 27, breadth 7*7 mm.

Closely allied to C. acutipes, 81., with which it agrees in every 

 feature of importance, but differing in colour, larger size, 

 basal sinuosities of the prothorax almost obsolete, posterior
