I have seen the type of C. areolatus, Bohem., which is a J , and 

 not a ? , as that author believed ; but I can only consider it as a 

 stunted example with a small horn development, which, however, 

 seems to be fairly common in Natal ; the smaller size may be due to 

 seasonal causes. 



Catharsius dubius, n. spec. 



Very closely allied to G. tricornutus ; the facies and the sculpture 

 are identical, but the shape of the cephalic horn is different. It is 

 produced in a somewhat quadrate lamina sharply carinate laterally, 

 the carina being the continuation of the suture of the genae, and 

 narrowed at about half the length into a round process, sharp at tip 

 and curving inwardly ; the shape of the forward horn is not unlike 

 that of G. melancholicus ; the two horns on the prothorax are 

 shorter and more erect, and the space between them is excavate 

 and smooth, like the anterior part of the prothorax. 



Female unknown.

Male : Head broadly emarginate in the anterior part of the 

 clypeus which is also slightly sinuate laterally, genae projecting 

 beyond the lateral edge of the clypeus, it is covered with elongate 

 punctures separated by very short transverse raised folds, and bears 

 in the anterior part a moderately compressed tooth leaning forward, 

 triangular at base and tapering towards the tip which is sharp, 

 this tooth varies in length from 3 to 4^ mm. ; prothorax similar 

 in shape to that of G. tricornutus, but the anterior part is 

 more excavated laterally, the two horns of the ridge are more 

 widely separated at base, diverge more at tip, and are also 

 shorter, the median impression is better marked, and the whole of 

 the posterior part, and also the horns, are closely granular, while the 

 whole of the anterior part is quite smooth ; elytra finely punctulato-
