A 2 . Anterior margin of clypeus broadly emarginate. 



Pale testaceous ; clypeus in the male with a sub-median 

 suture and a slightly raised keel ; apex of anterior tibiae 

 slightly curved outwardly sebakuensis. 



A 1 . Anterior margin of clypeus angular in the centre. 



Straw-colour, the two raised sutures on the clypeus not 



very high ovampoensis. 



MlCEOCAMENTA TRANSVAALENSIS, Breiisk., 



Stett. Ent. Zeit., 1898, p. 346. 



Male : Piceous, elytra very dark chestnut-brown, antennae chest- 

 nut-brown; head and clypeus deeply and somewhat closely punctured, 

 the latter is deeply emarginate laterally in the anterior part with the 

 upper angle of the emargination not sharp, the anterior part is 

 straight and strongly reflexed, the reflexed part being bounded by 

 a plainly impressed transverse line, and above the median part there 

 is a very distinct transverse keel running parallel with the clypeal 

 one, genae well developed, oblique ; inner joint of the antennal club 

 a little shorter than the one following ; prothorax somewhat convex, 

 ampliated laterally in the posterior part, anterior angles sharp, 

 posterior broadly rounded, lateral fringe of hairs not dense, surface 

 moderately deeply punctulate, punctures equi-distant, not closely 

 set ; scutellum closely punctate ; elytra sub-parallel, moderately 

 convex, more deeply punctured than the prothorax, and without 

 any visible costules ; under side clothed with greyish moderately 

 dense hairs ; anterior tibiae tri-dentate, tarsi not very long ; the 

 tooth underneath the claw quite plain. 



Length 5 mm. ; width 3 mm. 



Hab. Transvaal (Maghaliesberg). 



The only example of this species that I have seen is Herr Brenske's 

 type, which he kindly lent me. 



MlCROCAMENTA SEBAKUENSIS, n. Spec. 



Pale testaceous, with the head slightly more rufescent ; antennae 

 flavous ; head and clypeus deeply pitted but the former more closely 

 than the latter which, in both sexes, is very deeply emarginated 

 laterally in the anterior part with the upper angle of the emargina- 

 tion very sharp, the anterior part is deeply incised in the centre in 

 the male, and the outer angles very sharp, while in the female it is 

 deeply emarginate, and the angles on that account are less pro- 

 minent, the anterior part is reflexed but there is no distinct impressed 

 transverse line as in M. transvaalensis, and the surface is hardly 

 punctate, at about the median part there is a slightly bi- sinuate
