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 ' Ofversigt 

 Kongl. Vetensk.-Akad. Forhandl.' for 1879, in a memoir on the 

 Lepldoptera of Damara-land. 



The first of these is described as Callosune deidamioides and is, 

 I believe, only a slight variety of C. eveninus, which varies con- 

 siderably in the very characters used for discriminating C. deida- 

 mioides. 



The second is named O. damarensis ; it answers perfectly to some 

 of the male specimens of my 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 and 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 cJ 53 millim., 5 

 54 miUim. 



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. chnlcomiceta, 

 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 unwiUing 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 my 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
