Dry-season brood. rf Upperside : deep sulphur-yellow. Fore 

 wing : base and basal half of costa thickly irrorated with black 

 scales ; apical half of the wing black, with an enclosed, large, 

 irregularly triangular, orange-coloured patch, the apex of which is 

 more or less broadly rounded and blunt ; the orange colour extends 

 into the apex of the cell but is interrupted there by a black disco- 

 cellular spot that spreads diffusely inwards and joins the black 

 oblique bar which forms the base of the orange patch ; veins that 

 traverse this latter, black. Hind wing : uniform with a little black 

 scaling at extreme base ; termen with a dusky-black somewhat 

 narrow border (sometimes entirely absent) which decreases in 

 width posteriorly. Underside : a darker yellow, sparsely irrorated 

 with fusco-ferruginous short strigae and minute spots. Fore wing : 

 base and posterior area broadly, with a whitish pale virescent tint ; 

 the strigae and minute spots most numerous towards the apex and 

 along the termen ; interspaces 4, 5, 6 and 8 with a curved) sub- 

 apical series of small, rounded, dull ferruginous spots and a similar 

 spot on the discocellulars. Hind wing also with a ferruginous spot 

 on the discocellulars, followed by a postdiscal series of similar spots 

 in interspaces 3 to 8, all or most of them centred with white ; the 

 spots in interspaces 5, 6 and 8 the largest, those in 5 and 6 often 

 coalescent. Antennae and thorax anteriorly dull ferruginous, 

 thorax posteriorly and abdomen above fuscous black ; head, thorax 

 and abdomen beneath yellow. $ . Upperside : white faintly
