SOUTII-AFKICAN BUTTERFLIES. 
tlirec transverse roivs of suh-metaUlc or glistening darlc-edged spots. Fore- 
vjing : orange-yellow field very pale, wliitisli towards inner margin ; black 
spots as in Pierus, Cram., but their silvery- white centres more metallic, 
and tliose of the suhnargiiial row also hearing a silvery -white dot on their 
imvard side. Hind-iving : spots smaller than in Pierus^ those near 
base and in row before middle similarly disposed ; but those of discal 
row all separate, not forming an almost continuous streak, and with 
the third spot from costa (between second subcostal and radial nervules) 
out of line with and nearer base than the rest, and the three lower spots 
not inclining towards anal angle ; an additional row of similar spots 
midway hetiueen discal roio and hind-margin , sinuated similarly, hut not 
quite ixirallel to the former. 
^ Basal suffusion more tinged vnth yellow ; orange-yelloiu varying in 
extent from heing little more developed than in $ to pi^esenting a hroad 
discal field much as in Pierus, though of a paler and didler tint. Fore- 
wing : orange-yellow either entire from outer part of basal suffusion, or 
narrowly, broadly, or very broadly divided into two by the ground- 
colour on mediaji nervules. Hind-iviiig : orange-yellow always better 
developed than in (J, sometimes merging into basal suffusion, its outer 
edge strongly indented by fuscous, which sometimes forms separate 
inter-nervular spots. Under side. — As in ^, but the spots of hind- 
wing less metallic ; the hind-marginal fuscous spots better defined, 
especially in hind-wing. 
The characters italicised above seem constantly to distinguish this form 
from Pierus, — the principal ones being, on the under side, the smallness and 
separateness of the spots of the discal row and the presence of an outer row of 
spots besides the latter in the hind-wings, and the more or less conspicuous 
silvery-wliite dots marking inwardly the black spots of the siibmarginal row in 
the fore-wings. Usually Taikosama is smaller than Pierus, but two or three 
females from the upper districts of Natal, in which the upper-side orange, 
though dull in tint, occupies a wider space than usual, are quite as large. 
Much resembling these $ s is a from Zululand of unusually large size, with 
the upper side orange, though paler, developed quite as largely as in Almeida, 
Eeld. 
This form seems peculiar to the interior of South Africa, where it has 
evidently a considerable range. It was first brought prominently to my notice 
as probably separable from Pierus by a long series of specimens taken in 
Basutoland by Colonel Bowker ; and Mr. W. Morant subsequently sent me 
several examples from IN'atal, the Orange Free State, and the Transvaal, all 
taken in September and October 1870.
