White above, the base grey ; primaries with the apical two-fifths black, enclosing a large, reddish, orange, arched band, divided by the nervures into six parts; a minute black dot at end of cell; secondaries with a marginal series of six large triangular black spots: wings below white, base yellowish ; primaries with the apical area creamy yellow, bounded internally by a large, curved, diffused, orange patch, a black dot at end of cell; secondaries with a black-and-orange spot at end of cell. Expanse of wings 1 inch 6-10 lines. 2 . Wings above white, basal two fifths grey, obliquely in primaries, and terminating at second third of internal nervure in a darker grey spot; apical third black, inclosing a curved, orange band, divided by the nervures into five parts ; secondaries with well-developed, interrupted, angulated, blackish streak and 5 decreasing, triangular, marginal spots: primaries below nearly as in the male, secondaries pale yellow, with ochreous discal streak and a black dot at end of cell. Expanse of wings 1 inch 5-10 lines. 3 2, S. Africa (E. C. Buxton) ; 2, Orange River. Type, B.M. 94. TERACOLUS ANGOLENSIS, n. sp. 3 • Closely allied to the preceding, but the apical patch wider upon the costa and continued in the form of a tapering costal border nearly to the base ; orange patch half as wide again, its inner black border tapering towards the costa; marginal spots of secondaries more pyramidal and consequently separated : wings below destitute of yellow colouring, the diffused orange patch of primaries broader. Expanse of wings 1 inch 9 lines. 2 • Wings above white or yellow, markings as in the preceding species; but the orange band broader, the greyish areas darker, the border and band of secondaries much more pronounced, and the undersurface more uniform in colour. Expanse of wings 1 inch 7- 10 lines. 3, Angola (E. C. Buxton); 3 2, Congo (Curror). Type, B.M. I believe Felder to have described the female of this species as T. epigone 2 • 95. TERACOLUS OCALE. 2 • Anthocharis ocale, Boisduval, Sp. Gen. Lep. i. p. 584. n. 37 (1836). Guinea. Seems allied to the preceding species. 8c.
