Var. HOTTENTOTA, 
Plate XXIV., fig. 94. 
The livery of this variety closely reserables that of D. africana, but the 
antennae of the latter are wholly black.

Type : Black, clothed with dense long black hairs ; the five basal 
antennal joints black, the others yellow, patches and bands of the elytra 
pale yellow ; head and prothorax covered with fine, closely set, round, 
smooth punctures ; elytra somewhat ampliated in the posterior part, 
covered with closely set moderately deep punctures with sub-rugose walls, 
on each side are a dorsal basal arcuate lunule reaching the suture, and a 
narrow elongated lateral patch, a nearly median transverse band narrowed 
by nearly one-half from the median dorsal part to the outer margin and 
with the lower edge bi-incised, and a post-median as broad as the anterior 
from the suture to the middle, narrowed thence to the margin, with the 
upper edge bi-sinuate, and the lower bi-incised, the outer incision being 
the deeper of the two ; this band is often connected narrowly along the 
suture with the anterior ; the pubescence is black on the black background, 
and flavescent on the yellow patches and bands, but in the centre of the 
apical black ground is a patch of flavescent hairs. 
Length 12-17 mm. ; width 14i-6i mm. 
Hab. Cape Colony (Cape Town, Stellenbosch, Paarl, Ceres, Wor- 
cester, Malmesbury, Knysna, Mossel Bay). 
Var. OMEGA, Mars., 
Plate XXIV., fig. 96. 
Monogr., p. 585, pi. 6, fig. 11. 
Differs from the type in the pubescence being flavescent on the head 
and prothorax ; on the elytra the dorsal arcuate lunule and the two trans- 
verse bands are broadly separated from each other, the inner part of the 
two bands is not so broad as in the type form, and the outer part has the 
two edges much more deeply incised. 
Length 13-18 mm. ; width 6-7 mm. 
Hab. Everywhere in Natal and in the Transvaal.
