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. MananJiari (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.fiamda is a smaller 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.

Eanges 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 T. 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 

 horn the base through the lower half of the discoidal cell in 

 the secondaries.
