3. C. candida, race herero, form braunsi, Mihi. 
Mandibles a trifle shorter than in herero ? 
Labrum, antennz and contours identical, elytra a little more elongate. 
Pattern, the bands and rami narrower and in some examples the 
median rami are narrowly disconnected from the sub-marginal 
bands and the humeral rami are evanescent. 
Ground colour of elytra darker greenish-bronze. Coloration generally 
as in herero? but less brilliant. 
4, C. differens, Horn. 
Antenne long, slender, last joint narrowly truncate. A dense 
fringe of white hairs on either cheek. 
Labrum longer, male moderately, female considerably sub-triangularly 
produced and a little convex. 
Form, more or less elongate, elytral margins ; males nearly straight, 
females a little ampliate and both broadly rounded to apex. 
Prothorax about as long as broad, slightly rounded laterally and of 
nearly even width at base and apex. 
Pattern, bands and rami very broad pale testaceous. 
MANDIBLES NORMALLY ELONGATE. 
5. C. brevicollis, Wied. 
Antenne normal, not broadened at tip. 
Labrum and prothorax short, the latter a little more constricted at 
base than in preceding races. 
Form more transverse and less depressed, sexual differentiation of 
contours the same as in herero, but females less sinuate below 
shoulders. 
Pattern variable, lateral bands sometimes wholly absent, sometimes 
narrowly connecting the humeral with the median rami, but 
leaving a more or less wide interval between the latter and the 
postical bands, or with narrow sub-marginal bands from 
shoulders to apices. 
The humeral comma-shaped basal patch is usually connected with, 
but occasionally narrowly divided from the juxta-sutural band 
below it. 
The grouud colour is very dark bronze, showing up the yellowish- 
white pattern in sharp contrast.
