Show 1897.] BUTTERFLIES OF THE GENUS TERACOLUS. 33 64. TERACOLUS EVENINA. Anthopsyche evenina, Wallengren, K. Sv. Vet.-Akad. Handl.; Lep. Rhop. Caf. p. 12 (1857). Anthopsyche deidamia, Wallengren, Wien. ent. Monats. p. 35 (1860). Callosune casta, Gerstacker, Arch. f. Nat. xxxvii. p. 357 (1871). Callosune deidamioides, Aurivillius, K. Sv. Vet.-Akad. Forhandl. p. 45 (1879). Callosune Inornata, Westwood, App. Oates' Mat. Ld. ed. i. p. 338 (1881). Teracolus sipylus, 3 (nee $ ), Swinhoe, Proc. Zool. Soc. p. 444, pl. xl. fig. 11 (1884). Teracolus calllclla, H. G. Smith, Ent. Mo. Mag. xxiii. p. 32 (1886). This species extends practically throughout the S.-African sub-region except in the neighbourhood of Natal and Zululand. On the western side it is not recorded further north than Damaraland, but on the east it extends to Somaliland. T. sipylus ( = calllclla) is the extreme development of the wet form, and T. deidamioides represents the dry-season brood. The type of T. inornata is a very lightly-marked dry-season male. T. casta probably represents the dry-season form in the moister parts of Central Africa, having a dry-season upperside combined with a white underside, the ends of nervules being occasionally blackened in the latter part. T. evenina varies extremely in size in accordance with the dryness or humidity of the localities it frequents, some males from Namaqualand in Mr. Trimen's collection being hardly larger than typical T. evagore (Klug). 65. TERACOLUS CINCTUS. Teracolus cinctus, Butler, Ann. Mag. N. H. (5) xii. p. 105 (1883). The two males in the British Museum from Victoria Nyanza present much affinity to T. pallene (Hopff.), but with my present available material I must regard them as distinct \ T. cinctus forms an interesting link between the T. achlne and evagore groups. 66. TERACOLUS YERBURII. Teracolus yerburii, Swinhoe, Proc. Zool. Soc. p. 441, pl. xxxix. fig. 12 (1884). Teracolus swinhoei, Butler, ibid. p. 491 (1884). A purely Arabian species, being the representative there of the African T. daira. T. swinhoei is founded on a single female from Arabia, which is clearly only a yellow variety of T. yerburii. 1 " Among Mr. Millar's Teracoli I found two males of T. pallene (Hopff.), which he had caught in Natal. In m y paper I kept T. cinctus, Butl., distinct from that species ; but I now think I was wrong in doing so, and that it should fall as a synonym of T. pallene." [See No. 70, infra].-Q. A. K.
