median part of the clypeus which is broadly and deeply emarginate 

 in front ; the whole head is very roughly punctate ; the prothorax is 

 somewhat closely punctate, and the scutellum slightly so ; the 

 anterior tibiae are sharply bi-dentate. 



Length 16J—22J mm. (horns included). 



Hab. Southern Ehodesia (Sebakwe ; Salisbury, Mazoe, Matopos, 

 Bulawayo. 



I believe that M. soror of Kraatz is referable to this species. 



Feeds on Cassia pods, wild figs, Protea flowers, Acacia flowers, 

 and Acacia gum (G. A. K. Marshall). 



Var. flavipennis, Westw., Arcan. Entom., i., p. 185, pi. 45, fig. 5. 

 M. calvipes, Jans., Cist., hi., 1885, p. 140. 



Shape, size, and sculpturing of M. algoensis, but usually with the 

 body completely black, and the elytra flavous with the suture and 

 the two humeral spots black ; occasionally, however, and occurring 

 in the same locality as the melanic variety, are also found examples 

 with a rufescent prothorax and two longitudinal discoidal bands, as 

 well as partly red and partly infuscate prothorax. 



It is worthy of note that in this variety the clypeal horns of the 

 male are more parallel, and less broadly dilated at apex than in 

 the type form as figured by Westwood, but I have seen several 

 passages between the two. 



Janson's M. calvipes is an example which through abrasion or bad 

 usage has lost all traces of pubescence ; the apical part of the clypeal 

 horn is slightly more ampliated at tip than in the majority of my 

 male examples, and thus approximates more the type form ; in the 

 ype which was kindly lent me by Mr. Janson, the carina which 

 unites the two horns at the base is not distinct, but while in some 

 of my examples this carina is almost obsolete, it is either moderately 

 strong or very well developed in others. 



Length 17-22 mm. (horns included) ; width 8-10 mm. 



Hab. Transvaal (Johannesburg, Eustenburg, Lydenburg, Potchef- 

 stroom, Pretoria, Water berg) ; Bechuanaland (Eamoutsa).

Black, like M. algoensis, var. flavipennis, with the elytra pale 

 yellow, the suture and the posterior margin moderately broadly 

 black, the outer margin has a very narrowly black edge, and the 

 humeral patch on each side is brownish black. While the female is
