This species is readily distiuguished from all its allies by the well- 

 defined dark-coloured veins on the under surface.

The female originally described as belonging to this species proves 

 to be the pale form of the female of 2\ anteupompe ; the true female 

 of T. phcenius is of a pale sulphur-yellow colour and is much less 

 heavily suffused with grey at the base than in T. anteupompe ; the 

 veins on the apical area are also much less prominent and the disco- 

 cellular spot is smaller ; below, the winas are also sulphur-yellow, 

 the primaries only being crossed by an oblique white belt ; the veins 

 towards the outer margin are black, widening; towards outer margin 

 in the characteristic manner noticeable in the male. 



It is always a mistake to conclude too hastily that Indian and 

 African species are identical ; now that the sexes of this species are 

 finally determined, it becomes evident that Col. Swinhoe's decision 

 as to the identity of T. phcenius with T. dims of Sind is incorrect. 

 The female, which I at first supposed to be that sex of T. phcenius, 

 does indeed bear a considerable superficial resemblance to some of 

 the pale females of T. dirus, just as the many pale females of Colias 

 greatly resemble one another ; but when we compare the two red- 

 tipped females of T. anteupompe and dirus, we see at a glance that 

 they are utterly distinct : — the former has two-fifths of the wing 

 red, crossed by black veins and interrupted by an angular series of 

 small black spots ; the latter has the red area much more confined, 

 usually only forming an oblique band, but occasionally extending a 

 short distance beyond the black macular bar ; the outer margin is 

 also heavily bordered with black.
