internal streak, the under surface varying from pale buff to 
lemon-yellow. The females much resemble those of TJ’. opal- 
escens, but the ground-colouring of the under surface is 
yellower and the discal spots on the secondaries much more 
prominent, whilst the orange costal streak is paler. In the 
dry-season form of the female, apart from the slightly more 
sandy reddish colouring of the apex and of the secondaries, 
the absence of subapical spots and of the internal stripe on 
the upper surface, and the presence of a transverse tapering 
brown streak from the costa of secondaries on the under 
surface, serve to distinguish it from females of 7’. opalescens.

The range of this species is much greater than was formerly 
supposed. It occursin Damaraland and Ovampoland, Eastern 
Griqualand, Northern Transvaal, Matabeleland, Zanguebar, 
Nyasa, and Uganda. 
From the rarity of the dry-season form, it seems probable 
that it is confined to the drier parts of Eastern and Kast 
Central Africa. The female is the sex described by M. Dog- 
nin; the male is brimstone-yellow like the wet-season form, 
but with a clear orange apical patch. Hewitson has two 
examples of the female from the ‘Transvaal, but the orange 
area on the upper surface of the primaries is somewhat more 
restricted in these than in our Nyasa female.

This is a wet-season form, and is not at all likely to bea 
mere variety of 7. chromiferus, which also is a wet-season 
form occurring about 200 miles further northward. The 
species is only known to me at present through the admirable 
figure in Dr. Peters’s work ; but [ am satisfied that it is just 
as distinct as 7’, elgonensis.
