BUTLER ON LEPIDOPTERA [Nov. 19, Kilimanjaro had a common origin, but they are now too widely separated geographically to be regarded as one species, seeing that the differences of form and colouring between them are unquestionably constant. 43. ACR^IA SOTIKENSIS. Acrcea sotikensis, E. M . Sharpe, P. Z. S. 1891, p. 634, pi. xlviii. fig. 1. Kazamaza's, Euwenzori, 5300 feet, also 5600 feet. 44. ACRvEA PLANESIUM. Acrcea planesium, Oberthiir, Etudes d'Entom. 17th livr. p. 24, pi. 1. fig. 11 (1893). Kazamaza's, 5300 feet, between Kivata and Wimi camps, 7000- 8000 feet, and Salt Lake to Wawamba. 45. ACRIEA ACERATA. Acrcea acerata, Hewitson, Ann. & Mag. Nat. Hist. ser. 4, vol. xiii. p. 381 (1874); Ex. Butt. v. Acrcea, pi. 7. fig. 44 (1875). Acrcea vinidia, Hewitson, Ent. Month. Mag. xi. p. 130 (1874); Ex. Butt. 1. c. figs. 45, 46. Uganda. A. vinidia is the commoner form of the species, A. acerata being based upon a female specimen in which the subapical patch of the primaries is united to the large tawny area; every gradation from one type to the other occurs in a long series : on the under surface there is practically no difference, the number of spots varies, but their position is constant. 46. ACRCEA EPONINA. Papilio eponina, Cramer, Pap. Exot. iii. pi. cclxviii. figs. A, B (1782). Kampala and Uganda. Worn examples labelled Victoria Nyanza and Mumia were also obtained. 47. ACR^A LYCIA. Papilio lycia, Fabricius, Syst. Ent. p. 464 (1775). Var. Acrcea sganzini, Boisduval, Faune Ent. Madag. p. 34, pi. 6. figs. 6, 7 (1833). a. Kampala and Uganda (like A. sganzini, excepting that two-thirds of the hind wings are white). b, c. Kazamaza's, 5300 feet, and between Kivata and Wimi, 7000-8000 feet (typical A. sganzini). d. Salt Lake to Wawamba Co. (var. described P. Z. S. 1888, p. 6 6 =A. daira, Godm.). M y observation respecting A. ccecilia (P. Z. S. 1894, p. 566) was a lapsus due to the crowded state of our collection of these butterflies (owing to constant accessions) ; it really applies to A. sganzini, not to A. ccecilia, which is a distinct species.
