Male. — General colour sulplmr-yellow, the primaries having a post-median band 

 of four yellow spots somewhat deeper in colour ; a hind-marginal border of dusky 

 brown commencing at the apex and extending to about the first median nervule ; tlie 

 yellow spots enclosed b}^ a broad black bar, terminating somewhat abruptly above tlie 

 third median nervule ; a very minute black spot present at the end of the cell. 



The secondaries entirely sulphur-yellow without any markings. 



Underside. — Primaries whitish, the apical portion being faint yellow, with wavy 

 lines of lightish brown ; secondaries greenish-yellow, but entirely crossed by fine 

 wavy brownish lines, as on the apex of the primaries : a somewhat darker streak is 

 visible from the base to the hind margin. Expanse 2'2 inches. {Spec. ex. Vaal 

 River I Mus. Brit.) 



Female. — Ground-colour entirely white, the apical portion being relieved by four 

 spots of reddish-orange ; the hind-marginal border, which extends to above the sub- 

 median ncrvure, and the inner band, being brownish-red. The secondaries similar 

 to the primaries in colour and without markings ; the female only differing from the 

 male in the brighter-coloured apical patch. 



Underside. — Similar to that of the male, the secondaries being a little darker and 

 the wavy lines rather more strongly pronounced. Expanse 2-3 inches. {Spec. ex. 

 Kimhrrley I Sahin-Godman Coll.; Mm. Brit.) 



The " dry-season " form of the male has the ground-colour similar to that of the 

 " wet-season " form, but is perhaps a shade darker. The sub-apical row of spots on tlie 

 primaries is deeper orange-yellow, the black inner bar being a triHe narrower than in 

 the " wet-season " form. The secondaries do not differ in colour from the primaries.
