Show 1888.] LEPIDOPTERA FROM KILIMA-NJARO. 95 scales with the internal band, which is much darker than in T. antigone ; the cell, however, is not suffused with grey at the base as in that species ; costal band much blacker; marginal spots smaller towards anal angle. Expanse of wings 38 millim. Kilima-njaro (F. J. Jackson). Before proceeding to another genus I think it will be useful to refer to two species described by Herr Aurivillius in the 4 Ofversigt Kongl. Vetensk.-Akad. Forhandl.' for 1879, in a memoir on the Lepidoptera of Damara-land. The first of these is described as Callosune deidamioides and is, I believe, oidy a slight variety of C. eveninus, which varies considerably in the very characters used for discriminating C. deidamioides. The second is named C. damarensis; it answers perfectly to some of the male specimens of m y T. ignifer, var., and I do not doubt its identity with that form; it may be a good species, but the points which separate it from typical T. ignifer are very slight, the principal distinction being the pinker tint of the under surface of the secondaries. 7. MYLOTHRIS NARCISSUS, sp. n. Nearest to M. trimenia, of the same colours, but the primaries quite distinct in pattern, the base being broadly black (to the middle of the discoidal cell) in the male and dark brown in the female; the costal margin black ; apical black border and marginal spots of male fully three times as broad as in M. trimenia; in the female there is a broad dark brown external border tapering on the costal margin, its inner edge acutely tridentate on the median branches and its posterior termination, obtusely pointed, extending one third towards the base ; first marginal black spot of secondaries enlarged in both sexes, but especially in the male, other spots smaller than in M. trimenia : on the under surface the apex of primaries and entire surface of secondaries are sulphur-yellow in the male aud chrome-yellow in the female, not gamboge-yellow as in the S.- African insect; there are also no black marginal spots on the primaries and those of the secondaries are smaller. Expanse of wings 3 53 millim., 2 54 millim. Forests of Tiveta (Hannington). The costal margin of the primaries is noticeably shorter in this species than in M. trimenia. Mr. Jackson obtained a species of Terias allied to T. chalcomicetat or perhaps that species; it is not absolutely constant in pattern, and some examples differ so little from the common type of Aden that I am unwilling to separate it. As it has been suggested to me that T. chalcomiceta is " only a variety " of T. hecabe, I may say once for all that the phrase is utterly unintelligible to me ; there is only one Terias (to m y knowledge) in Aden, and it is about as unlike T. hecabe as any two species of Terias can well be. Undoubtedly we have the strongest evidence that there once was only one Terias and that all the species now existing are local races or climatic forms of |
