BUTLER ON LEPIDOPTERA [Nov. 17, tain, 6500 feet June 27th, 7400 feet June 30th; Kondowi, Lower Nvika, Nov. 30th, 1895 ; Kasungu Mountain, 5945 feet Feb. 29th, 7425 feet March 2nd, 7200 feet March 5th, 1896. Most of the specimens are of the ordinary European type. S7. TERTAS LEONIS. Terias leonis, Butler, Ann. & Mag. Nat. Hist. ser. 5, vol. xvii. p. 222, pl. v. fig. 6 (1886). o*, Kondowi, 4000 feet alt., Nyika, Feb. 21st, 1896. This is the first example I have seen from Central Africa. 88. TERIAS REGULARIS.

TERACOLUS MUTANS. 2 • Teracolus mutans, Butler, Ann. & Mag. Nat. Hist. ser. 4, vol. xix. p. 459 (1877); 6 • P. Z. S. 1896, p. 126. o* 2 t Mpimbi, Upper Shiri River, March 24th and 25th, 1896. Dry-season form. Differs in the great enlargement of the discal series of spots on the secondaries, these being salmon-buff tinted in the male, and sulphur-yellow in the female; the primaries in the latter sex are also coloured more nearly as in the male, but the salmon-buff area is washed with yellow; on the under surface the whole colouring of the male and the bands upou the yellow area of the female are deeper and redder. S, Mwankanka, Loangwa River, Senga, Sept. 7th, 1895; 2 , Loangwa Valley forest, Senga, August 30th, 1895. The female contained "pale orange ova" (R. ft). When describing the male of T. mutans I compared it with T. vesta (meaning the southern species usually so-called) ; but T. vesta is an Abyssinian species, identical with T. velleda of M. Lucas, and differs from the South-African butterfly in the much brighter colouring, with somewhat differently formed and much redder bands on the under surface of the secondaries: the southern species is only the wet-season form of T. arglllaceus, and is T. vesta of Trimen (nee Lucas); the latter, on the under surface, is much nearer to T. aurlglneus, whereas T. arglllaceus is certainly the southern representative of T. mutans. 90.
