distributed all over the globe, thirteen of the genera contain species which are natives of Africa, three of them being peculiar to that region--namely Abantis, from Mozambique, Ceratrichia, Butler, from Western Africa, and Caprona, Wallengren, from Southern Africa. _LEPIDOPTERA RHOPALOCERA._ Family PAPILIONIDÆ. Genus PAPILIO, Auct. 1. (1) PAPILIO DEMOLEUS, _Linnæus_. _Papilio Demodocus_, Esper. Ranges from Western Tropical Africa to the Cape of Good Hope. Genus CALLIDRYAS, Boisduval; E. Doubleday, Gen. D. Lep. p. 66. _Catopsilia_, W. F. Kirby, Syn. Cat. p. 481.[76] 2. (1) CALLIDRYAS SWAINSONII, Westw. _Colias Pyrene_, Swainson, Zool. Ill. vol. i. pl. 51. (Not of Linnæus, which is an Indian species, belonging to the genus _Thestias_, Boisduval.) _Callidryas Pyrene_, Butler, Lep. Exot. pl. 16, f. 8–10. _Callidryas Florella_, Boisduval; Trimen, Rhopal. Afr. Austr. p. 68; but not of Fabricius nor Donovan, Nat. Repos. III. pl. 90. Many individuals of this species were taken at the Motloutsi River, varying in having the black spot of the disc of the fore wings, and the orange spots on the under side of the hind wings. A specimen from Guinea, received by Mr. Hope from Mr. Westermann of Copenhagen as the _Florella_, Fabr., is identical with the South African specimens of Swainson’s species. The type specimen described by Fabricius, drawn by Jones (Icones, v. 2, Dan. Cand. pl. 5, f. 3, 4), copied by Donovan, is from Sierra Leone, and was, and still is, in the Banksian Collection. _C. Swainsonii_ is very widely dispersed. 3. (2) CALLIDRYAS RHADIA, Boisduval; Trimen, p. 69. _Callidryas Castalia_, E. Doubleday, Gen. D. Lep. p. 68 (not of Fabricius). Two specimens captured at Tati. The Rev. H. Rowley sent it from the Zambesi to the Oxford Museum. Genus TERACOLUS, Swainson. 4. (1) TERACOLUS SUBFASCIATUS, Swainson, Zool. Ill. 2 ser. Ins. pl. 115[77]; Boisduval; Trimen. _Ptychopteryx Bohemanni_, Wallengren, Lep. Caffr. p. 18. Originally described from the Burchell Collection now at Oxford. Six specimens from Tati. The species appears to be very rare, as Mr. Trimen had not seen an individual. The female has the extremity of the fore wings brilliant orange-red, instead of pale orange-yellow, as figured by Swainson. 5. (2) TERACOLUS AGOYE, Wallengren, Lep. Caffr. p. 15; Trimen, p. 325. _Anthocharis Eosphorus_, Trimen, Trans. Ent. Soc. 1863, p. 523. One specimen. Locality not noted. Genus PIERIS, Auct. 6. (1) PIERIS MESENTINA, Cramer, pl. 270, f. A, B; Godart; Boisduval; Trimen, p. 35. _Papilio Aurota_, Fabricius, Ent. Syst. III. i. 197. Many specimens taken at Bamangwato, the Motloutsi River, Tati, Gubuleweyo, Inyati (November 30, 1873), the Gwailo River, and at or near the Victoria Falls.
