the hind-wings." He does not, however, specify what differences 
exist. 
Geyer {op. cit.) figures a $ from " South Africa," which agrees 
very well with specimens taken near Grahamstown and in KafFraria 
Proper, but in one point differs from every other example that I have 
seen, viz., in the narrow but comjDlete separation of the disco-cellular 
longitudinal black band from the hind-marginal black border on the 
upper side of both fore-wings. 
Boisduval, describing northern specimens under the name Trito- 
qenia, mentions that the $ has a whiter ground-colour than the 
This is quite the exception in southern examples. I took one such $ 
near Grahamstown in 1870, but all the others I have seen exhibit a 
more or less decided inclination to pale-yellow. 
Hopffer (op. cit.) notes that the ground-colour varies as much in 
the Mozambique specimens as in those from Nubia and Senegal, 
and mentions one example of the variety with the brown under-side 
colouring. 
The general resemblance of this pied butterfly to the Marbled 
White" Satyrince of Europe {Melanargia Galathca, Linn., and allies) 
has been noticed by many lepidopterists. The form and position of 
the longitudinal band of the fore-wings and the straight transverse 
ante-median band of the hind-wings are very singular, and the only 
other species in which similar (though smaller and duller) markings 
occur is Teracolus Evciiina, Wallengr., 
I had the pleasure of observing this beautiful insect in life for the first time 
at the end of January 1870, near Grahamstown, and during the following 
month met with it not uncommonly in that neighbourhood. It frequented 
steep hillsides on the borders of woods, but never entered the shade of the 
woods themselves ; delighting in the Scabwsa flowers, which were abundant in 
such stations. It is very conspicuous on the wing, and is easily captured, being 
rather slow of flight and settling frequently. I afterwards saw the species near 
Uitenhage. There is no part of South Africa proper where this butterfly 
appears to be abundant, but it is evidently numerous in the South-Tropical belt 
between 23° and 20°, twenty-five examples occurring in Mr. J. A. Bell's small 
collection made in Damaraland, and nineteen in a series collected by Mr. A. W. 
Eriksson between the northern limit of the Transvaal country and Gubulewayo, 
in Matabeleland. Mr. H. Barber informed me that two specimens he sent from 
Matabeleland were captured while drinking at a hole dug to collect water.
