SOUTH-AFRICAN BUTTERFLIES. 
hrown, U^sDER side. — Fore-wing : blackisli markings not clouded with 
white ; white markings generally more or less tinged with sulphur- 
yellow. Hind-wing: all the white markings usually more or less 
tinged with sulphur-yellow along margins of wing. 
As above noted, the size of this species is very variable. I have 
observed that, although large examples are found throughout the 
South- African range, all the smallest s|)ecimens come from the drier 
(usually upland and interior) tracts. 
Variety A. — $ and $ (Melanarge, Butl.). 
$ Ground-colour decidedly creamy; along hind-margins a dull 
ochrey-reddish tinge tinging both black border (especially about apex 
of fore-wing) and outer part of its creamy spots. Under side. — 
Hind-wing and apical hind-marginal area of forc-iuing suffused with 
dull ochrey-reddish (in the paler p}ortions tuith a tinge of pink) dusted 
loith dark-grey ; the dark bands and border very ill-defined reddish- 
brown, in some specimens scarcely distinguishable. 
$ (Two examples). Ground-colour pale sulphur-yellow. Under 
SIDE. — As in J, but the ochrey tint paler, not so red, and with the 
position of the typical white markings vaguely indicated by some 
whitish clouding. Fovc-wing : pale markings sulphur-yellow. 
(Hah. — Natal, Delagoa Bay, Transvaal, Griqualand West, Damara- 
land, and Somaliland.) 
From Mr. Butler's description (loc. cit.) I think that there can be 
no doubt that his Melanarge, of which he describes three male examples 
from Somaliland, is identical with the Variety A. just described.-^ I 
should also refer to the same variety his Lacteipennis (Ann. and Mag. 
Nat. Hist, 4th Ser., xviii. p. 489, 1876), from Abyssinia, notwith- 
standing its unusually small size (exp. al. i in. 7 lin.), if it were not 
for his description of the hind-wings as having several submarginal 
black spots, sagittate (with the points upwards), towards apex," which 
looks as if the ordinary white-spotted black border of the upper side 
were wanting on those wings. 
I have not been able to discover any character by which Tritogenia, 
Klug, can be separated from Eriphia, Godt. The description of the 
latter only di{Fers in giving four instead of six white spots in the black 
border of the hind-wing ; but these spots vary a good deal in size and 
distinctness, and Godart probably did not include the first large costal 
spot (which, indeed, is but narrowly separated from the central 
white field) ; and I have seen several examples in which the sixth 
(last) spot is almost obsolete. Mr. Butler, in the paper last cited, 
observes : ' ' Eriphia, which I have examined from Angola, is a larger 
and more creamy-coloured insect than H. Tritogenia (with which it 
has been united), . . . the markings are not quite the same on 
1 Under the name of Herpcenia itevata, Mr. Butler has recorded some examples from 
Kilima-Njaro {F. J. Jackson), stated to differ from H. melanarge only in its considerably 
larger size (55 mm. = about 2 in. 2 lin.), and in the broader subbasal black belt and larger 
white marginal spots in the hind- wings [Proc. Zool. Soc. Lond., 1 888, p. 96).
