SOUTH AFRICAN BUTTERFLIES. 
with blackish along and near inner margin and also near hind- 
margin. 
These descriptions of larva and pupa are made from numerous 
living specimens received from Colonel Bowker in August 1887, 
having been collected by him near D'Urban, Natal. The larvae had 
almost finished their supply of food by the time that they arrived, and 
I liberated them all except one which was suspended for pupation, 
and from which I obtained a ^ Severina on the 9th September. Seven 
of the pupge received had the date of pupation attached, and I thus 
ascertained that the duration of the chrysalis state was from fourteen 
to seventeen days. The eight examples (three five that I reared 
from these Natalian pupce, as well as several others reared at the same 
time by Colonel Bowker and afterwards forwarded to me for compari- 
son, were all of the rather smaller form, with duller- tinted under side 
marked by heavy blackish neuration, proper to the winter or dry season ; 
but one of the $ s that I reared was of the Boguensis variety, with a 
very completely developed oblique costal bar marking the extremity of 
the discoidal cell. 
The typical ^ varies to some extent in the width of the black 
l^orders on the upper side, as well as in the size and distinctness of 
the white spots which they contain ; in one example (from Delagoa 
Bay) the inner part of the border of the hind-wings is so feebly 
developed that these spots are scarcely separated from the white 
ground.'^ On the under side the tint of the hind-wing is sometimes 
of a duller, greyer tinge, and in these examples the neuration is 
strongly and generally fuscous-clouded ; while in the specimens which 
have this surface pale and bright the nervures are often almost free of 
clouding, more especially on the disc. Two rather small $ s from the 
Limpopo Biver exhibit the latter character in a very marked degree, 
and in that respect resemble the very closely allied P. Creona, (Cram.), 
of West Africa. 
In a $ that I captured near Grahamstown, the basal pale- yellow 
suffusion of the fore-wing on the under side is abnormally developed, 
filling the discoidal cell and spreading beyond it along the costa. The 
same peculiarity exists to a much less extent in two other $ s, — one 
from KafFraria Proper and the other from Natal. 
The typical ^ on the upper side presents a variable width in the 
borders, and the ground of the fore-wings sometimes (and of the hind- 
wings very rarely) is nearly white. On the under side of the hind- 
wings the clouding of the neuration is less variable than in the J, being 
commonly well developed. 
An example from Barberton, Transvaal, received from Mr. J. P. 
Cloete in March 1888, is of a remarkably deep rich yellow above, with 
the dark border abnormally wide, — in the fore-wings almost touching 
1 It is evidently on a similar i from Port Natal that Felder {op. cit.) has founded his 
P. Agripfina. The feature in question is a character of the African (Jsof Mesentina, Or.
