174 M. Louis Peringaey ou new genera and species of 



usual, but the posterior ones, which are very slender in comparison 

 with the others, are sinuate outwardly and deeply emarginate in 

 the inner part a short distance from the base to the apical part ; 

 basal joint of anterior tarsi triangular, not emarginate externally. 

 Female unknown. Length 15, width 7 mm. 



Sah. Mozambique (Eikatla). 



Easily distinguished by tbe incui'ved posterior tibiae ; 

 this character occurs also, but in a lesser degree, in the $ 

 of M. ijratiosus. 



M. gratiosus, n. sp. 



Black, moderately shining; head and pro thorax finely punctulate, 

 the latter broader than long, rounded laterally at base and apex ; 

 elytra elongated, very little ampliated in the middle, nearly plane 

 in the anterior part and with a long posterior slope, covered with 

 irregular, sharp, short tubercles closely set, and not disposed in 

 series, supra-lateral part sharp, almost carinate, lateral part sub- 

 foveate. Female unknown. Length 15-17, width 8-8^ mm. 



Sah. Zambezia (between the Zambeze and Limpopo 

 Rivers). 



Elytra narrower than in M. (Soleno^nents) longipes, 

 Fahr., less convex, and much less retuse behind, with 

 the outer sides more carinate, and the prothorax more 

 plane and acutely carinate laterally ; the basal joint of 

 the anterior tarsi is triangular and not emarginate in- 

 ternally as in 31. longipes, carinatus, etc. 



M. s'p^irius, n, sp. 

 Black, covered with a light brown tomentum ; head and pro- 

 thorax very shortly setulose, the latter hardly convex, cai'inate 

 laterally ; elytra of the $ ovate, convex, gradually slopitig behind, 

 supra-lateral part sharp, carinate, densely granulose and with two 

 series of small tubercles on each side, the space between the first 

 series and the suture also tuberculated irregularly. In the 9 the 

 prothorax is a little more convex and has a round smooth spot on 

 each side, and the punctures are also deeper ; the elytra are very 

 convex, abruptly declivous behind, with the granules and tubercles 

 smaller and the two discoidal series better defined. Length 14-15, 

 width 8-9 mm. 



Hah. Zambezia (between the Zambeze and Limpopo 

 Rivers, Manica). 



The $ is closely allied to the same sexof il/. gratiosus,
