Papilio dryope, Cramer, Pap. Exot. i. pi. lxxviii. figs. E, F (1779). Kivata, 6000-8000 feet, and Salt Lake to Wawamba. 40. BYBLIA ACHELOIA, var. CASTANEA. Hypanis castanea, Butler, P. Z. S. 1885, p. 759. d d 5 Victoria Nyanza, Jan. 3rd ; Malamba, 7000 feet, Jan. 13th. I agree with Prof. Aurivillius that the characters which distinguish this form from typical B. acheloia are seen to be variable when sufficient specimens are obtained, and therefore its distinctness as a species cannot be maintained; the extreme development of this form seems to be reached in Somali-land. 41. CYRESTIS CAMILLUS. Papilio camillus, Fabricius, Sp. Ins. ii. p. 11 (1781). Kampala and Uganda. An extremely variable species, sometimes very heavily banded, but often almost as lightly as in the closely allied Madagascar form C. elegans; indeed, I fully expect to see these two supposed species completely linked by transitional vai*ieties, just as, in the New-World genus Helicopis, the palest and darkest types of H. cupido grade one into the other. 42. ARGYNNIS EXCELSIOR, sp. n. (Plate XLII. fig. 4.) d. Nearly allied to A. hanningtonii L (PL XLII. fig. 3), from which it differs as follows :-Outer margin of primaries convex; colouring above deep tawny ; outer border slightly narrower, with its inner edge undulated and separated from the submarginal series of black spots, which are also smaller: under surface with the primaries orange-tawny, excepting the apical area, which is dull creamy yellowish clouded with green ; ground-colour of secondaries dull creamy yellowish, clouded with green ; silver markings rather larger and more prominent than in A. hanningtonii; otherwise precisely similar, the disposition and character of the markings being the same. Expanse of wings 40-42 millim. Female slightly duller and paler, with the borders less black and the marginal pale spots consequently longer than in the males. Expanse of wings 39 millim. Euwenzori, 5600 to 9000 feet. Twelve more or less worn examples were obtained : Mr. Scott Elliot has a note that it " fertilizes the violet ( Viola abyssinica).," There can be no doubt that this mountain form and that of 1 Elwes, Trans.
