Dry- season form. 



Differs in the great enlargement of the discal series of spots on 

 the secondaries, these being salmon-buff tinted in the male, and 

 sulphur-yellow in the female ; the primaries in the latter sex are 

 also coloured more nearly as in the male, but the salmon-buff area 

 is washed with yellow ; on the under surface the whole colouring 

 of the male and the bands upon the yellow area of the female are 

 deeper and redder.

The female contained " pale orange ova " (R. G.). 



When describing the male of T. mutans I compared it with T. 

 vesta (meaning the southern species usually so-called) ; but T. vesta 

 is an Abyssinian species, identical with T. velleda of M. Lucas, and 

 differs from the South- African butterfly in the much brighter 

 colouring, with somewhat differently formed and much redder bands 

 on the under surface of the secondaries : the southern species is 

 only the wet-season form of T. argillaceus, and is T. vesta of Trimen 

 (nee Lucas) ; the latter, on the under surface, is much nearer to 

 T. auriyineus, whereas T. argillaceus is certainly the southern 

 representative of T. mutans.
