threo obliquely-transverse rather irregular reddish-grey streaks, — of 

 which the first is short, just beyond middle, from costal nervure to 

 first subcostal nervule, — the second, at some distance beyond middle, 

 rather broad, from first subcostal nervule to submedian ner\nire, but 

 very widely interrupted from third to first median nervules, — and the 

 third, considerably beyond the second, short, dentate on median ner- 

 vules. On hind-mai'gin of both wings a series of minute black spots 

 marks the extremities of the nervules. 



^ Much 'paler, inclining to sulphur-yclloiv ; llach hordcr not so dark 

 and more restricted in fore-iuing and wanting in hind-iving. Fore- 

 wing : costa rather faintly irrorated with dusky atoms from base to a 

 point about one-third of its length ; black border apically as broad 

 as in ^, its internal edge less regularly excavated, its costal commence- 

 ment much more attenuated and farther from base, and its hind-mar- 

 ginal termination very abrupt on first median nervule ; small yellow 

 inter-nervular costal streaks better marked ; rarely the hind-marginal 

 border is interrupted by a yellow streak on second median nervule ; a 

 small (usually minute) black spot at extremity of submedian ner\n.ire. 

 Hind-wing : a hind-marginal series of very small (sometimes minute, 

 and more rarely towards apex of moderate size) black spots, at extre- 

 mity of each nervule as far as first median. Under side. — Hind-wing 

 and costal-apical border of fore-wing of an uniform dull pale rufous- 

 creamy, varying in depth of tint, its minute fuscous speckling more 

 general than in ^ ; markings usually duller and fainter than in $, 

 sometimes very indistinct. The $ exhibits much variation in the tint 

 of the under side, some examples being of quite a pallid cream-colour 

 with only a slight reddish tinge, while in others the rufous colour is 

 very pronounced, 



]\rr. Butler has recently {Ann. and Mag. Nat. Hist., March 1886, p. 214) 

 expressed the opinion that Brigitta is the Southern representative of Candace, 

 Feld., from Abyssinia. An examination of the S and $ of the latter in the 

 British Museum has convinced me tliat the two are identical, Candace being 

 simply rather more faintly marked and less reddish on the under side than 

 usual. 



Among its South-African congeners, T. Brigitta is distinguished in both 

 sexes, but more especially in the female, by tlw p-evalent reddish tint of the 

 tinder side, as ivell as of the cilia both above and below.'^ In this respect it 

 appears to approach T. llerla, Macl., from Northern Australia, but I have not 

 seen the latter species, and can only judge by the published descriptions of it. 

 Apart from the peculiarity mentioned, Brigitta differs in the following parti- 

 culars from its close ally, T. Zoe, Hopff., viz. : — {^ ) Ground-colour a deeper, 

 warmer yellow ; black border of fore-wing narrower costally and at posterior 

 angle — above which it is usually narrowly interrupted ; border of hind-wing 

 much narrower, and becoming more or less submacular and obsolete towards 

 anal angle ; ( ? ) ground-colour a deeper, richer yellow, without fine dusky 



^ I think it not unlikely that Terias ScruH, Westw. (App. Oates's Matabeleland, &c., p. 

 342, 1881), is a variation of the ? Brigitta, in which the under-side markings are obsolete ; 

 these markings being very faint in many examples of Brigitta, and in one specimen from 

 Delagoa Bay (unusually red beneatli) almost imperceptible.
