Show 22 MR. R. TRIMEN ON BUTTERFLIES FROM [Jan. 16, ocelli of the hind wings, though small, are distinctly marked. A second much-worn female, taken in the same locality on 22nd February, appears to resemble the first very closely. Genus MYOALESIS, Hiibn. 9. M Y O A L E S I S SAFITZA, Hewits. Mycalesis safitza, Hewits. Gen. Diurn. Lep. p. 394. n. 10, pi. 66. fig. 3 (1851). All the examples (two from Christmas Pass and twelve from Mineni Valley) have the underside ocelli strongly or very strongly developed, a feature which, as I have pointed out (S.-Afr. Butt. hi. p. 395), is characteristic of the summer or wet-season form of this Mycalesis. The specimens in all respects agree with the tropical type-form more closely than with extra-tropical examples, one character being the feeble expression of the ocelli on the upperside of the fore wings, which in two of the males are obsolete, and a second the more strongly-marked common pale median streak on the underside. Genus M E L A N I T I S , Fabr. 10. M E L A N I T I S L E D A (Linn.). Papilio leda, Linn. Syst. Nat. i. 2, p. 773. n. 151 (1767). Of nine specimens (six males and two females from Mineni Valley and one male from Christmas Pass) taken from 27th February to 26th March, all but one-a female from the former locality captured on 12th March-are of the typical smaller and darker form, with largely-developed underside ocelli, wilich is characteristic of the summer or wet season. All the dated material obtained on the Natal Coast by M r . A. D. Millar and myself and at Delagoa Bay by the Eev. H . Junod confirms Mr. L. de Niceville's discovery at Calcutta, that in this widely-distributed and highly variable species there are two well-marked seasonal forms, viz. 1, a summer or wet-season race, superiorly duller but inferiorly with well-developed and conspicuous ocelli, and possessing non-angulated or but slightly angulated fore wings ; and 2, a winter or dry-season race, superiorly brighter, more or less rufous, but inferiorly with very imperfect, reduced, and obsolescent ocelii, and possessing well-angulated fore wings. As in the case of Mr. Selous's example just referred to, occasional specimens of the dry-season form are met with in the wet season, and vice versa ; but these are so very few that they can only be regarded as accidentally late survivors of the preceding, or early precursors of the succeeding generation. 11.
