Head smooth, large (3-4 x 3-7 mm.'), convex, roundly declivous 

 to anterior margin and above eyes, constricted behind orbits and 

 widely impi-essed across base; frontal sulci deep, narrow, long, 

 oblique, converging from posterior transverse impression to 

 clypeus, the out-turned anterior part of their course hardly 

 marked; clypeus with median part truncate, intermediate angles 

 short, feebly developed ; preocular sulcus lightly impressed ; pre- 

 ocular process projecting as far as eye, rounded : eyes deeply 

 enclosed in orbits; postocular prominence large, as long and 

 as prominent as eye; two supraorbital punctures on each side. 

 Mandibles thick (as in Conopterum <^). Antennas short, lightly 

 incrassate; joints 2 and 3 short, of equal length, 5-11 greatl}' 

 compressed, narrow and setigerous on edge, apical joint about 

 one-third longer than penultimate, obtuse at apex. Prothorax 

 hardly wider than head, longer than broad (4"25 x 38 mm.), 

 narrowed to base, convex, declivous to base; basal area depressed; 

 sides parallel in front of posterior angles, widely rounded at 

 posterior angles, sinuate on each side of base; anterior margin 

 truncate, with angles strongly and obtusely advanced ; base 

 widely sublobate, truncate ; l^order narrow, prominent, lightly 

 reflexed, of equal width along sides, dilatate at anterior angles, 

 thick on base ; marginal channel deeply impressed along sides; 

 median line finely marked; a lightly marked longitudinal de^^res- 

 sion on each side near basal sinuosities. Elytra narrow, hardly 

 wider than prothorax (9x3-85 mm.), Itevigate ; sides lightly 

 rounded; humeral angles hardly marked; border narrow, not 

 thickened or elevated at humeral angles ; four punctures in a 

 wide depression on base of each elytron near humeral ani^le; a 

 marginal row of punctures on each elytron (not closely placed nor 

 in a lateral channel) ; suture deeply impressed. Legs light ; 

 anterior tibife lightly bidentate (lower side as in Eutoma); 

 intermediate tibite without any strong dentiform projection at 

 external apical angle. 



Length 17 "5, breadth 3-85 mm.
