178 Beetles of the Cicindela brevicollis group 
Prothorax short transverse, of even width at base and apex ; 
sparsely covered with white decumbent hairs except for the usual small 
denuded spaces on either side of the median suture. Legs setose ; the 
sides of the abdomen, the sternze and coxe densely clothed with 
decumbent white hairs. 
Prothorax and head glowing bronze with bright metallic green 
interspersed in the depressions and about margins. — First four joints 
of the antenne, the denuded space below the lateral margins of the 
prothorax, the suture and the legs above glowing metallic red. The 
sternal parts and the abdomen bright metallic green. 
Elytra ; ground colour greenish bronze with coppery reflections ; the 
pale testaceous markings are disposed as in c/athrata. Prothorax short 
as in brevicollis, but not constricted at base, a little wider and more 
hairy. Elytra; short, plane above; males nearly straight, a little 
widened about middle; females sinuate below the shoulders and con- 
siderably ampliated about middle. 
The Willowmore form of this race is a little more elongate, otherwise 
the shape in either sex is identical with that of the Okahandja form. 
The marginal bands and rami are finer and in some examples the 
median rami are attenuated and interrupted near the point of junction 
with the marginal band. 
The juxta sutural band is shorter and sometimes briefly interrupted 
at the point where it is strangulated. 
The ground colours of the prothorax and elytra are the same as in 
the Okahandja form, but darker and less brilliant. 
The distinguishing feature, the spatulate ultimate joint of the male 
antenne, is the same, though in some examples it is not so evident as 
in others. 
The races that I have attempted to portray have mostly a very 
extended range within South African limits, which roughly may be 
taken as that of the 16th parallel of S. latitude. Over the whole of 
this area they display remarkably little variation or modification of 
the distinctive points that characterize them, considering how intim- 
ately they are related to one another and how often they overlap. 
On reference to the Table of Distribution it will be noticed that 
in many localities two or more of these races occur in association 
or in near proximity to one another, and yet in these spots the 
distinctions between them are fully maintained and show no signs of 
mergence. Per exemplum, at Committee Drift on the Great Fish 
River clathrata and intermedia have been taken together on the same 
day and at a spot which is very near the limits of both their respective 
ranges to the eastward and westward. Nevertheless neither of these 
races show any modification of their distinctive characters.
