Dej., bertolonai, Horn and clathrata, Dej. For some reason unknown 
to me vivida, Boh. is placed as a variety of sub-species neglecta, to 
which it is not even the most nearly related. The claims of C. 
bertolonw to specific rank I have already dealt with in my previous 
paper, and they can therefore be omitted from further review. 
Adding reliqua mihi to the list (which under the old arrangement 
would probably be included as another sub-species of brevicollis), 
we have the following anomalies. Intermedia occurs frequently in 
association with either clathrata or fasciculicornis, as I have 
previously shown. From _ Bothaville, O.F.S., I have received 
clathrata and reliqua, and in November, 1919, at the Upper Tongaat, 
Natal, I personally came across and captured reliqua, intermedia and 
Jasciculicornis within a few hundred yards of one another. Each of 
these forms has a very extended range and well defined character- 
istics, and, as at present classified, they are all sub-species of C. 
brevicollis, which obviously they cannot be. They are equally 
impossible as mere varieties. Their authors originally described them 
as species, and as such some of them at least must still be recognised. 
Intermedia, neglecta and discoidea appear to be very intimately 
related, and so far as my present knowledge goes, they can only be 
accepted as geographical forms or races of one another. Dviscoidea, 
De}. has priority of description, and must therefore rank as species, 
with the other two as sub-species of it. C. vivida, Boh. and C. 
reliqua mihi are sutticiently distinct from one another and from 
C. brevicollis (which is also isolated geographically) to be retained as 
species, in the same section with discordea. 
C. brevicollis, Wied, is a very local race and only owes its 
importance, as head of the group, to being the earliest described. 
Clathrata has a much wider range than brevicoll/is, whose place in 
nature appears to be that of a strictly localized race or sub-species of 
the former. However; this change of arrangement is not desirable, 
and I think it would be. better to treat each as species. The larger 
size, lighter ground with deeper yellow pattern, and the non-lability 
to vary that pattern on the lines affected by brevicol/is, are sufhicient 
reasons for keeping them apart. 
The following classification appeals to me as the best that can be 
arranged for the Ethiopian members of the group, upon our present 
knowledge. C. tetradia, Fairm, and C. quadraticollis, Chd. with its 
sub-species, all from Madagascar, are unknown to me and are there- 
fore omitted :——
