but tlie elytra are more ampliated laterally and less 

 elongated behind. I am not quite sure that the ?, 

 which I describe from one example only, is truly that of 

 31. S2)urius. 



M. fallax, n. sp. 



Black, moderately shining; head and prothorax as in M. spurius 

 and M, gratiosus ; elytra elongate-ovate, depressed on the anterior 

 part of the disk, and gradually sloping from the median part to 

 the apex in both sexes, broader at the base in the $ , covered with 

 closely-set granules not large enough to be called tubercles, and 

 having on each side two lines of more or less coalescing small 

 tubercles — the outer line is the best defined of the two, the supra- 

 lateral part sharp in both sexes and densely granulate ; basal joint 

 of the anterior tarsi not emarginate. Length 15-1<), width 9i-10mm. 



Hab. Zambezia (Upper Limpopo). 



Easily recognized by the depression of the basal part 

 of the elytra and the gradual sloping towards the apex. 



M. ovampoanus, n. sp. 



Black, moderately shining; prothorax a little convex, somewhat 

 attenuate laterally in front, one-third broader than long, slightly 

 sloping at apex, nearly smooth ; elytra of the $ elongate, rather 

 convex from the median part of the disk, sub-aculeate behind and 

 gradually sloping, supra-lateral part sharply carinate, anterior part 

 of the disk smooth, the rest with short tubercles, irregularly set 

 but forming somewhat indistinct series on each side of the 

 posterior declivous part ; basal joint of the anterior tarsi not 

 emarginate inwardly. In the $ the elytra are very convex, covered 

 with a greyish-brown tomentum, and the basal part near the 

 scutellum is nearly smooth ; they are densely granulose, and the 

 two dorsal series of larger granules are distinct. Length 15-17, 

 width 9 mm. 



Hah. Ovampoland. 



A little more aculeate behind and less declivous than 

 M. longipes, Fahr,, of which it is a very close ally. The 

 $ is distinguished by the denuded space at the base of 

 the elytra, as well as by the form of the basal joint of the 

 anterior tarsi, which is not emarginate.
