70 SOUTH AFRTC AX BUTTERFLIES. 



with blackisli along and near inner margin and also near hind- 

 margin. 



These descriptions of larva and j;mjj« are made from numerous 

 living specimens received from Colonel Bowker in August 1887, 

 ha\"ing been collected by him near D'Urban, Natal. The larvas 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 pupje 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 pupa3, 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 Bogiiensis 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 

 borders 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 River 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 vai'iable 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 ^, 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 fnim Port Xatal that Felder (o^x cit.) has founded his 

 P. Agripiina. The feature in question is a character of the African (5 s of Mesaitina, Cr.
