the head, the clypeus of which is sinuate in the centre, and some- 
what short; the short prothorax is serrulate laterally and the basal 
angles project longitudinally beyond the line of the base; scutellum 
sealy; elytra slightly broader than the prothorax at the base, slightly 
sinuate past the humeral part and strongly ampliated thence to the 
posterior part, the suture is costate, and there are faint traces of two 
or three costules, both the humeral and postical calluses are very 
distinct and the surface is deeply punctate, the punctures being 
only moderately closely set and filled each with a greyish-white 
scale; propygidium extremely closely punctulate and very briefly 
pubescent ; pygidium broader than long, covered with contiguous 
sub-flavescent scales; abdomen strongly bulging out laterally and 
very convex, covered also with contiguous small white scales, pectus 
and episterna clothed with appressed thick squamose hairs, which in 
the former are mingled with a sub-fulvescent pubescence; legs 
scaly ; anterior tibiz tri-dentate. 
I have not ascertained by dissection the sex of the only example 
known to me, but I am satisfied, in spite of the shape of the antennal 
club, that it is a g, owing to the shape of the spurs of the hind 
tarsi. 
Length 27 mm.; width 144 mm. 
Neighbourhood of Zambesi River (Ikuta), communicated by Herr 
Brenske. 
Group DIPLOTAXIDHES. 
Labrum transverse or arcuate, not incised; anterior cox strongly 
oblique and vertical at apex; clypeus either very short in both sexes 
or strongly prolonged and even bi-lobate in the male. 
The shape of the labrum and of the anterior coxe characterise 
this group which is represented in South Africa by five species, 
belonging to one or possibly two genera, the males of which have 
the two or three basal tarsal joints dilated and hairy underneath ; 
this dilatation can also be traced in the female of some species.
