from which it is, however, easily distinguished through the long 

 impressions on the head. Length 21-22 mm. ; width 6-7 mm. 



Hab. Zambezia (Salisbury), Transvaal, no exact locality. 



Very closely allied to M. sulciger, Chaud., from the west coast of 

 Africa, but the head is a little less broad than in that species ; the 

 humeral angle of the elytra is much less developed, the base less 

 tuberculate, and the space between the edge of the base and the 

 striae narrower, more abrupt, and not aciculate, as in M. sulciger.

Mentum excavate, with a broadly median triangular tooth the 

 base of which fills the cavity ; the apical part is not very sharp, but 

 is conspicuously carinate longitudinally in the middle ; the inner part 

 of the lateral lobes is very oblique, and the outer part very slightly 

 ampliate in the middle ; maxillae slightly sinuate outwardly, incurved 

 at the tip in a long, sharp tooth, the outer lobe much longer than the 

 inner one, which is densely ciliate ; two last joints of maxillary palpi 

 a little shorter than the first, the last one hardly inflated, but com- 

 pressed, truncate at the tip, last joint of the labial also subcylindrical 

 or sometimes subfusiform, shorter than the penultimate one by one- 

 third; mandibles long, interlocking ; labrum short, bisinuate ; epistoma 

 with a setigerous puncture on each side of the median part ; a seta 

 over the posterior part of the eye ; antennae reaching the posterior 

 angle, first joint as long as the two following, the others moniliform ; 

 prothorax more or less rounded at the base, the posterior angle well 

 defined, and with a marginal seta above it and one near the anterior 

 angle ; elytra convex, either parallel, ampliate in the posterior part, 

 or elongato-ovate ; abdominal segments with two median setigerous 

 punctures, the last one with four ; anterior tibiae strongly digitate, inter- 

 mediate ones with two spines ; some species are winged, others are not. 



This genus is represented in Europe, Asia, including Japan, Java, 

 the Philippine Islands, North and South America and Africa (Sene- 

 gambia, Guinea, Nubia, Kordofan, Abyssinia, Zanzibar mainland).
