452 Dr, A. G. Butler—A Revision 
Ward described the wet-season form (which is largest) 
with almost plain yellow under surface in the male, about 
two black spots in the primaries and an orange costal streak 
to the secondaries being the only markings on that surface ; 
in the female the apical area of the primaries and the second- 
aries are buff on the under surface, the former with a sub- 
apical black bar representing the inner boundary of the black 
border of the upper surface and a discocellular black spot, the 
latter often with a slender interrupted angular discal stripe. 
T. nothus is represented by two intermediate forms, which 
occur in both sexes. ‘The first has the under-surface pattern 
of T. Mananhart (typical), but the apex of the primaries and 
the secondaries are washed with rosy sienna; the second is 
slightly less reddish below, but has the addition of a longitu- 
dinal brown stripe through the centre of the secondaries ; the 
female also has indications of striations on these wings. 
T. flavida is asmaller form in which the striation of the under 
surface appears in the male, but the angular band in that sex 
and the subapical band in the female are obsolete. Finally, 
there is a true dry-season form of which we possess the male 
only ; it is small, the apex of primaries and the secondaries 
below fleshy buff, indistinctly striated, but without longitudinal 
streak or angular discal stripe.

Ranges from the Victoria Nyanza southwards to Nyasa 
and eastwards to Mombasa and Bagomoyo. 
Both types of the species are undoubtedly sexes of the 
wet-season form; the bad colouring of Staudinger’s figure 
led Mr. Marshall to suppose that 7. vulnerata was “ clearly 
the dry-season form,” but he is mistaken, for we have the 
latter. It is very rosy beneath, the male having the apical 
half and the secondaries, excepting towards apex, fleshy 
sienna, transversely striated with brown and more or less 
spotted; there is also frequently a longitudinal dusky streak 
from the base through the lower half of the discoidal cell in 
the secondaries.
