much more sloping, there is no small median tooth, and the lateral 

 one is placed at some distance from the lateral impression, which 

 has a short carina running underneath, the anterior part and the 

 sides are very closely and roughly granulose, but the median lobe is 

 closely punctured except the upper part w^hich is roughly granulose ; 

 elytra narrowly striate, striae smooth, intervals finely and closely 

 punctulate. 



Female (figs. 15, 15a) : Similar to that of C. jacchus, the cephalic 

 horn, however, is emarginate at middle at the tip and the outer 

 angles are sharper, the clypeus is more deeply emarginate in the 

 centre; this also holds good for the small development, which greatly 

 resembles that of C. capensis and can only be distinguished by the 

 clypeus which is not deeply incised, and by the striae, which are 

 smooth instead of being distinctly punctate.

Black, head and prothorax slightly opaque, elytra very shining. 



Male (fig. 17) : Head very rugose, clypeus slightly emarginate, 

 in the middle of the head there is an incurved horn 11 mm. long 

 in the great development, carinate laterally in front and behind and 

 with the base extending on the whole width of the clypeus, this horn 

 is very rugose ; prothorax declivous and having in front a quadrate 

 process about 6 mm. wide projecting above the declivity, deeply 

 emarginate triangularly in the centre and with the angles truncate 

 and slightly emarginate at tip, the anterior part has a moderately 

 deep impression under each angle of the median lobe, and there is 

 on each side, close on the outer margin, two short but very distinct 

 ridges running parallel to one another, the anterior part is covered 

 with closely set granules, and* so are the sides of the posterior part, 

 but the lobe itself is rugulose and the base slightly shining and very 

 closely punctate ; in the median development (figs. 12, 12a) the 

 cephalic horn is only 5 mm. long, and the median lobe very short 

 and not deeply emarginate, while in the smallest development,
