PIERID.E. 59 



in the Interior of South Africa. Described from a female 

 specimen figured by Mr. Swainson." Boisd., Sp. Gen. Lep. 

 Of this species I have not seen any example ; nor do I know of one ex- 

 isting in any collection. From the description above quoted, it would seem 

 to approach the Genus Thestias in arrangement of colouring and marking.

$. White; with greyish-ochreous, slightly violet-glossed, 

 apical patch. Fore-wing : costa dusted with blackish ; 

 ochreous at apex divided into five elongate marks by the 

 brown-clouded nervules, externally bordered by a brown, 

 violet-glossed edging, internally by a black stripe ; the latter 

 stripe becomes merged, on first median nervule, with a glossy, 

 deep-black, inner-marginal band, widening from base, and 

 becoming very broad and tending upwards beyond third me- 

 dian nervule, but extending quite to anal angle and lower 

 portion of hind-margin. Hind-wing : a duller black band, 

 of considerable width, extends along costa, ending suddenly, 

 with a concave excavation, just before apex ; small black 

 spots along hind-margin at ends of nervules, as far as second 

 median nervule ; blackish clouding from base extending a 

 little into discoidal cell, and between median and submedian 

 nervures. UNDER-SIDE. Whitish, or yellowish-white. Fore- 

 wing : apex faintly tinted with yellow ^both it and inner- 

 marginal band being indicated by a faint-greyish tinge ; 

 between first and third median nervules, not far from hind- 

 margin, are two rounded blackish spots (in some specimens 

 a third smaller spot below them, immediately beneath third 

 median nervule). Hind-wing : slightly more yellowish than 

 fore-wing ; spotless ; costa edged with chrome-yellow near 

 base. 



$ . Fore-wing : apical patch less distinct, without viola- 

 ceous gloss, tinged with orange-yellow, its outer margin rusty- 

 brownish, its inner border blackish, macular ; the latter stripe 

 continued by two blackish spots to third median nervule, 

 where the lowermost of the two spots almost touches ex- 

 tremity of inner-marginal band, which is much narrower, 

 paler, and shorter than in $ , leaving anal-angular region 

 wholly white ; disco-cellular spot larger, rounder. Hind- 

 wing : slightly yellowish ; beyond middle, traces of a black-
