of the $ deeply emarginate internally as in all Micrantereus, anterior 

 femora sub dentate at apex ; underside punctured; legs very 

 rugose. In the $ the legs are shorter, the tibise not emarginate 

 inwardly, and the anterior femora not dentate. Length 18^-20, 

 width 11-12 mm. 



Hah. Upper Limpopo River. 



M. carinatus, n. sp. 



Black, covered on the upper part with very short tomentose 

 pubescence, which is denser and a little longer on the elytra ; head 

 and prothorax very finely and closely punctured, prothorax a little 

 attenuate laterally in front and behind ; elytra elongate-ovate in 

 the $ , convex and gradually dehiscent behind, bi-costate on each 

 side, the costaj consisting of elongated, coalescing, short tubercles, 

 with the intervals irregularly tuberculated, suture smooth, raised ; 

 in the $ the elytra are more convex and therefore more abruptly 

 declivous behind and they have three distinct, sub-tuberculate 

 costge on each side ; legs rugose, anterior femora not sub-dentate in 

 the $ , intermediate tibia3 so deeply emarginate inwardly that the 

 base of the sinuation is almost toothed ; underside black, shining, 

 punctulate. Length 19-215, width 11-13 mm. 



Hah. Betcliuanaland (Ramoutsa), Upper Limpopo. 



Larger than 31. {Bolenomerus) longvpes, Fahr., propor- 

 tionally more massive, but while in M. longipes the dorsal 

 longitudinal series of tubercles are hardly more raised 

 than the tubercles in the intervals, and are thus very 

 indistinct, they are very well defined in the present 

 species, more raised, and although closely sub-tuber- 

 culated, often smooth and carinate on the posterior 

 declivity. 



M. luctuosus, n. sp. 



Black, covered with a greyish tomentum ; head and prothorax 

 shagreened, the latter as broad as long and hardly attenuate 

 laterally at apex and base ; elytra elongated, very little ampliated 

 laterally in the median part, not much attenuated, and not very 

 abruptly declivous behind, each elytron with two discoidal series 

 of more or less elongated and coalescing tubercles or rather large 

 granules, with a few sub-seriated ones on the first and second 

 intervals, and a double or treble irregular series between the second 

 tuberculate costa and the sub-carinate supra-lateral part ; legs 

 long, the anterior and intermediate tibite sinuate inwardly as
