This handsome species inhabits Natal, Damara Land, Ceylon, Bengal, Madras. Male, Inyati (November 30, 1873); females, near the Gwailo River (October 19, 1873), and Impakwe River (February 12, 1874). 13. (3) CALLOSUNE EVIPPE, Linnæus; Clerck, Icones, pl. 40, f. 5; Cramer, pl. 91, f. F, G; Godart; Boisduval; Lucas, Exot. Lep. pl. 37, f. 1. Tati; and between Inyati and Gubuleweyo, December 1, 1873. 14. (4) CALLOSUNE OMPHALE, Godart; Boisduval; Trimen, p. 50. Near the Victoria Falls, in January. 15. (5) CALLOSUNE ANTIGONE, Boisduval, Sp. Gén. p. 572; Trimen, p. 52. Both sexes, Ramaqueban River, February 14, 1874; also females at the Gwailo River in October. These females have no orange on the upper side of the fore wings. 16. (6) CALLOSUNE CASTA, Gerstaecker in Decken’s Reisen in Ost-Afrika, pl. 15, f. 1, 1 a. Taken at Tati. 17. (7) CALLOSUNE KEISKAMMA, Trimen, p. 56, pl. 2, f. 3, 4. Var. _Anthopsyche Topha_, Wallengren, Wien. ent. Mon. iv. p. 34. Ramaqueban River, July 28, 1874. Kirby cites Klug’s _Pontia Evarne_, Symb. Phys. t. 6, f. 1–4, as identical with this species, but the rounded fore wings of the male, with the black exterior margin, and the submarginal row of black spots on the hind wings, at once separate these two insects. See the observations of Mr. Weale on this subject (Trans. Ent. Soc. 1877, p. 273). 18. (8) CALLOSUNE INORNATA, Westw. Alis supra albis, basi nigro parum pulverosis, anticis macula trigona distincta apicali aurantia: alis anticis infra albis apice albido-lutescenti, intus magis brunnea; alis posticis lutescenti-albidis, linea recta longitudinali media paullo obscuriori. Expans. alar. antic. lin. 19. The locality of this very simply coloured species is not recorded. 19. (9) CALLOSUNE IONE, Godart; Boisduval; Lucas, Exot. Lep. t. 37, f. 4; Reiche in Ferr. and Gal. Voy. Abyss. t. 30, f. 1–8; Hopffer in Peters’s Reise Mossamb. t. 21, f. 1–6; Trimen, p. 43. _Anthopsyche speciosa_, Wallengren, p. 16. _Anthocharis Erone_, Angas, Kafirs Ill. pl. 30, f. 3. Two males, taken at Tati. The species of this genus, in which the males have the extremity of the fore wings marked with a brilliant blue or pale purple patch, are so closely allied together as to suggest the possibility of their being geographical sub-species; they appear indeed to be constant in their characteristic markings, and the females are even more distinct than the males, which they are generally so unlike that their sexual relations might readily be suspected.
