each side there is a basal dorsal band gradually slanting towards the 
suture and reaching to a third of the length, an elongated lateral one, and 
a sinuate median patch reaching from the suture to the median dorsal 
part ; above this patch is a somewhat elongated, more or less triangular, 
or hamate marginal one the inner point of which does probably coalesce 
with the outer part of the median dorsal in some examples ; in the posterior 
part and under the median patch is a sub -transverse rounded one, and a 
lateral broader than the one above it, also hamate, very nearly con- 
nected with the discoidal, and prolonged as a narrow band along the outer 
margin.

Black, covered with a black and greyish pubescence, dense underneath 
and on the head and prothorax, moderately so on the elytra, near the apex 
of which is a silky, whitish flavescent patch, the five basal antennal joints 
black, the other five yellowish rufescent ; head and prothorax covered 
with almost contiguous, sub-rugose punctures, frontal part with a more or 
less distinct smooth patch ; elytra plainly shagreened, bands and patches 
pale yellow, on each side are a sub-elongate ovate basal dorsal patch and a 
shorter elongate lateral one, a transverse moderately broad band consist- 
ing of two patches united in the centre of the disk by a band narrower 
than the patches by one-half, and a post-median band formed in the same 
manner, and having thus the appearance of being deeply scooped in the 
anterior and posterior borders. 
Var. DEEEPTA. 
The elytra bear each three superposed patches set between the suture 
and the median dorsal part, and three other, of nearly the same size, set 
along the suture opposite the dorsal three. The difference in the shape of 
the markings is simply due to the obliteration of the two transverse spurs 
connecting the dorsal patches as in the type form.'-' This variety is from 
Clanwilliam, Cape Colony.

* The livery of this rare varietal form is quite similar to that of Coryna lugens 
(pi. xxiv., fig. 123), which, however, does not belong to the same genus.
