Male : Head semicircular, clypeus emarginate, genae not pro- 

 jecting beyond the edge of the clypeus, it is covered with very 

 short, raised, closely set, transverse folds, and bears at a short 

 distance from the base an erect horn tapering from the base, where 

 it is from 3 to 5 mm. high, this horn tapers to a sharp point which 

 curves slightly outwards ; prothorax declivous in the anterior part, 

 and having in the centre two conical horns projecting forward, but not 

 diverging much at tip, and with the anterior basal part somewhat 

 excavate outwardly, the surface is covered with a fine, closely set 

 granulation, but the anterior part, including the excavated part, is 

 smooth, and there is also a smooth patch on the upper part of the 

 base of each horn ; elytra as broad as the prothorax, convex, but 

 no^ gibbose, finely punctato-striate with the intervals smooth or 

 very vaguely aciculate ; eighth stria carinate from the base to about 

 one-third of the length. 



Female : Head a little more circular than in the male, and with 

 the clypeus not emarginate at tip ; the sculpture is similar, but 

 instead of an erect horn it has a short, not much raised, transverse 

 tri -sinuate carina the median part of which is shghtly bi-tuberculate ; 

 prothorax not very convex, a little declivous close to the anterior 

 margin, the short declivity is bounded by a short, distinct, trans- 

 verse ridge 4|- mm. across, and emarginate in the centre, the 

 anterior sides are very sloping, the posterior part of the disk has 

 a distinct median longitudinal impression reaching from a short 

 distance from the transverse sinuate ridge to near the base, it is 

 covered with closely set granules, and on each side of the posterior 

 longitudinal impression there is a round, smooth space ; elytra as in 

 the male. 



Length 26-27 mm. ; width 15-18 mm.
