is carinate, the carina is slightly emarginate in the centre, con- 

 spicuously sinuate laterally, and ends in a sharp angle, the outer 

 margin itself being strongly angular in front of the terminal end of 

 the carina ; the anterior angle of the prothorax is very sharp. 



Female : Head with the clypeus semicircular, but with the gense 

 more ampliated than the clypeus, and less angular behind than in 

 the other South African species of the genus, it is very closely 

 granular, and bears in the centre a short conical horn, sharp at tip, 

 and about 2 mm. in height ; prothorax abruptly declivous in front, 

 apex of the declivity bounded by a ridge slightly emarginate at 

 centre, rounded on each side, and shghtly sinuate from there to the 

 lateral part which is sharply angular with the angle standing above 

 the lateral impression, but not overhanging it, the sides are noi 

 excavated, and the anterior angles are very sharp, the surface is 

 covered with very fine and very closely set granules, the posterior 

 part of the disk has no impressed line ; elytra as broad as the 

 prothorax at base, convex, but not quite sub-gibbose at middle, very 

 finely striate with the intervals coriaceous, eighth stria conspicuously 

 carinate, the carina reaching from the base to two-thirds of the 

 length. 



Length 21-22 mm. ; width 17-18 mm.

Piceous black on the upper side, piceous brown beneath ; head 

 semicircular, not emarginate in the centre, but a little aculeate at 

 the junction of the gense with the clypeus, and covered with very 

 closely set, transverse raised folds, but the genge are covered with 

 closely set, sub-conical, small tubercles ; in the male the centre of 

 the head is produced into a sharp vertical tooth with a very broad 

 base, and a sloping fine ridge behind on each side ; in the female 

 the centre of the head is produced into a sloping, shield-like process, 

 sinuate laterally on the upper part and slightly bi-dentate at tip ; 

 the prothorax is covered with very closely set granules, and is very 

 abruptly declivous in the anterior part in both sexes, and the top of 

 the declivity is carinate and bi-sinuate ; in the male the declivity is 

 more abrupt, the edge is sharper, the median part is crenulate and 

 has a sharper and longer tubercle on each side, and the lateral 

 impression above the anterior angle is quite smooth ; in the female
