SOUTH-AFEICAN BUTTERFLIES. 
A specimen of the $ sent from Pinetown, Natal, in 1869 by Mr. 
W. Morant is remarkable for having the hind-wings white except for 
a faint ochreous-yellow suffusion in basal third, and a very narrow 
ochreous-yellow hind-marginal border like that of the fore-wings ; 
while the yellowish of the under side is but little darker than in 
the $. A similar but much worn, was taken (paired with the 
near D'Urban by Colonel Bowker in 1879. 
I had not seen the $ Pigea in 1862, but mistakenly took for 
it the $ of the closely-allied but smaller P. alba, Wallengr. Colonel 
Bowker sent only $ s from Kaffraria Proper, but I met with both sexes 
on the Natal coast in 1867. 
Wallengren {loc. cit.) describes what purports to be "P. Simana 
(Hpfr.) $ ; " but his description is undoubtedly that of a <J, and agrees 
thoroughly with the characters of the $ Pigea; moreover, in some 
rough sketches of types sent by this author to Mr. W. F. Kirby, and 
kindly lent by the latter for my inspection, " P. Simana, Hpfr.," 
is undoubtedly the representation of a ^J, and to all appearance that of 
Pigea, 
Colonel Bowker has sent me four pairs of the sexes captured in copula ; 
three of these ^vere received in 1879, and one in 1881. The s of these 
pairs differ in size only, but one of the $ s (as noted above) is abnormally pale. 
I found this species rather numerous near D'Urban and Verulam, on the 
coast of Natal, in February, March, and April 1867. It was active on the 
Aving, keeping to open places about the borders of woods, and reminding one 
(except for the deeper yellow of the females) of the abundant Pieris Rapoi 
of Europe. It ranges to Kinsembo in Congoland, and is reported by M. 
Oberthiir to have been received from widely separated localities in Tropical 
Eastern Africa.
