penicillate at the angle, upper lobe of maxillae short, very transverse, 

 thickly penicillate, inner lobe stiffly ciliate, apical joint of labial palpi 

 S'.vollen, pyriform, apical joint of maxillaiy ones fusiform not sharply 

 acuminate at the tip ; head with the clypeus somewhat short, quadri- 

 dentate at the tip, broad and reflexed somewhat in the manner of 

 ScarahcBiis ; prothorax convex, attenuate laterally in the anterior 

 part and thence nearly parallel, base not vei'y arcuate ; scutellum 

 short, sharp at tip ; elytra not much ampliated at the humeral part, 

 verj' slightly emarginate below it or not at all {ateuchoides) and not 

 strongly attenuate thence towards the apex ; pygidium in the male 

 slightly declivous fonvards ; anterior tibiae tri-dentate, the teeth 

 equally distant from each other, and with the apical one only slightly 

 curved, all the claws double with the smaller ones half the length of 

 the outer, which in the intermediate and posterior legs are deeply cleft. 

 In the male the intermediate claws have a tooth underneath more or 

 bss similar in shape to that of some Monochclus. The genus 

 i.icludes four species, one of which, M. atrox, which I have not seen, 

 might prove to be identical with M. naialcusis, but Burmeister's' 

 description of it is far from satisfactory. The genus is purely South 

 African. 



Key to tJic Species. 



Elytra and pygidium clothed with contiguous yellow or sulphur- 

 yellow scales, hind tibire simple (itciicltuides. 



Elytra with lanceolate scales along the posterior part of the 

 suture, the outer margin and the pygidial part ; hind tibiaa some- 

 what deeply emarginate on the upper margin above the apex, the 

 angles of the emargination sub-dentate iiatalcnsis. 



Elytra and pygidial part clothed with somewhat sparse, sub- 

 squamose, appressed hairs ; hind tibiae with a long, mucro-like 

 spur on the upper margin above the apical part, but not far 

 from it tran-iiaalensii;.

Male : Black, with the scutellum, the elytra, the pygidial part and 

 the abdomen entirely covered with minute contiguous flavous or 

 sulphur-yellow scales, the prothorax is also covered with appressed 

 sub-squamose hairs, as well as with a flavescent pubescence, and 

 along the base there is a broad band of scales ; head pubescent, 

 rugose, clypeus quadri-dentate, but the two median teeth project 

 far beyond the other two, which are not in a line and are almost 

 sub-lateral and rounded at the tip ; elytra elongate, sub-rufescent,
