suture and a sutural, slightly raised keel above it, which, however, is

 moderately dense ; scutellum punctulate ; elytra sub-parallel, but a 

 little ampliated laterally behind, not much convex, moderately deeply 

 punctate and with the lateral fringe of hairs somewhat dense ; inner

MlCROCAMENTA OVAMPOENSIS, n. spec. 



Female : Very light straw-colour, antennae and palpi of the same 

 hue ; shape and size of M. sebakuensis, but at once distinguished by 

 the shape of the clypeus the anterior margin of which is bi-sinuate 

 owing to the centre being plainly aculeate, the outer angles are, 

 however, as sharp as in M. sebakuensis, but the upper angle of the 

 lateral sinuation is not sharply aculeate, and the two ridges on the 

 clypeus are more like raised sutures than keels ; the vestiture is the 

 same as in M. sebakuensis. 



Length 7 mm. ; width 3^ mm.

TULBAGHIA, n. gen. 



Mentum long, broader at the apex than at the base, but with the 

 sides straight, fused with the ligula, the labial palpi are inserted on 

 the lateral angle, the ligula being narrow, transverse, deeply sinuate 

 in the middle, rounded laterally and extending only from one palp 

 to the other, the outer face of the mentum is slightly convex and 

 clothed with very long, dense, bristly hairs, but slopes very strongly 

 towards the apex ; last joint of labial palpi very swollen ; maxillae 

 massive, upper lobe produced into six sharp arcuate teeth, last joint 

 of maxillary palpi nearly cylindrical, and as long as the three pre- 

 ceding ones taken together ; mandibles very robust, triangular, with 

 the upper edge chisel-like and cleft in the middle ; no labrum ; 

 clypeus briefly vertical and slightly sinuate in front, hollowed above 

 with the margins reflexed, as long as the head and separated from 

 it by a plain, transverse suture, eyes very bulging, broadly exposed 

 on the upper side, divided in front by a narrow canthus of the genae, 

 head plane ; antennae 10-jointed ; club 7-jointed in the male, the 

 joints very long, foliate, equal in length and width and arcuate, third 

 joint as long as the two preceding ones taken together and produced
