suture and a sutural, slightly raised keel above it, which, however, is 
more suture-like in the female, gene well developed, oblique; inner 
joint of antennal club of the male much shorter than the one follow- 
ing; prothorax somewhat densely punctured, lateral fringe of hairs 
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 
spur of anterior tibiz slightly bent outwardly at tip in the male. 
Length 64-74 mm.; width 3+-3? mm.

MIcROCAMENTA OVAMPOENSIS, n. spec. 
Female: Very light straw-colour, antenne and palpi of the same 
hue; shape and size of M. sebakwensis, 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 34 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; maxille 
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 gene, 
head plane; antenne 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
