of the under side of the hind-wings dark clouded throughout ; and | 
those of the 1 8 8 i pairs are both yellowish on the upper side (with the I 
costal streak of the fore-wing in one thinly prolonged almost to the 
disco-cellular spot), while on the under side one of them has the dark i 
neuration of the hind-wings only marked near the hind-marginal 
border, but the other has it strongly developed throughout (in this ! 
latter specimen the narrow costal bar of the fore-wing is complete). 
A $ and $ which I captured at D'Urban, Natal, in June 1865, 
and also a $ taken at the beginning of the following August, are 
smaller and with duller-tinted, more dusky-veined under sides than ' 
those which I afterwards took in that locality and near Grahamstown 
in the summer months of January, February, and March. The $ 
referred to is almost white on the upper side ; in this respect resembling 
a considerably larger ^ from South- West Madagascar, which is in the 
South- African Museum. | 
This is a common and widely-spread butterfly over all the wooded parts of 
South Africa ; its most westerly known locality is Knysna, on the coast of the i 
Cape Colony. Although prevalent always about the edges of woods, it by no ] 
means confines itself to them, but flies actively over open ground at hand, often 
stopping to visit flowers. The $ s are swifter than the $ s, but both sexes 
were in the flights of PierincB which I witnessed on 6tli February 1870 
at Highlands, near Grahamstown, and I captured several females on that 
occasion.

1 Mr. Alfred D. Millar, of D'Urban, at my request, was good enough to capture and date 
numerous examples of this (as well as of other Pierince) during 1887-88, and to send them 
to me. Five cJs and four ? s taken on 15th August, and a i taken on the 22d, are all of 
the duller more dusky- veined form ; a S taken on 22d September is larger and brighter 
beneath, showing some approach to the summer or wet season form ; and three S s taken 
on 3d December and a S and ? taken on 29th January are all of the bright pale-yellow 
under side, with the neuration lightly and unequally blackish.
