the Liiul-wiDgs." Ho 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 Kaffrana 

 Proper, but iu one point differs from every other example that I have 

 seen, viz., in the narrow but complete 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- 

 gcnia, 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" Satyr ince of Europe (Mdanargia 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 Tcracolus Eccnina, 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 Scahiosa flowers, which were abundant in 

 such stations. It is very conspicuous on the wing, and is easily captured, beuig 

 rather slow of flight and settling frequently. I afterwards saw the species near 

 Uitenhage. There is no part of South Africa proper Avhere 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 ]\Ir. 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.
