Hab. ad ripas fl. Niger ( W. A. Forbes). 

 Mus. nostr. 



Of this species Forbes's collection contains only a single specimen, 

 but we have others, which are hardly distinguishable from it, from 

 Zanzibar. Its nearest ally seems to be A. lycia, from which it 

 differs at first sight by its more rufous tint, which colour also per- 

 vades the transverse subapical light spot of the primaries, so that it 

 is hardly to be distinguished from the other markings of the wing. 



9. ACE.EA CECILIA. 



Papilio cacilia, Fabr. Spec. Ins. ii. p. 34. 



This is also a species of wide range in West Africa, whence it 

 passes eastward to the White Nile. 



10. AcRiEA calyce, sp. n. (Plate XVII. figs. 1, 2.) 



cj . Alls rosaceis, anticis interdum fuscis sed area apicali interna 

 semper semihyalina ; macula cellulari, aliis tribus (una ad 

 cellulce finem duabus infra earn in linea transversa positis) et qua- 

 tuor ultra cellulam vigris ; posticis dense {prcecipue ad basin) 

 nigro maculatis, margine externo nigro maculas rosaceas inclu- 

 dente ; subtus ut supra, sed anticis vitreo micantibus, posticis ad 

 medium glaucescentibus. Antennis nigris, palpis omnino albido 

 rosaceis ; abdominis dimidio postico rubido. 

 Exp. 2'3 inches. 



Hab. ad ripas fl. Niger (W. A. Forbes) ; Cape Coast Castle, 

 Dahomey. 

 Mus. nostr. 



Several specimens of a species allied to A. adnatha, Hew., for 

 which we have not been able to find a name. We have other 

 examples from Cape Coast Castle and from Dahomey, showing that 

 the species is probably far from uncommon in this region. The 

 specimens vary a good deal inter se, the basal half of the primaries 

 being more rufous in some specimens than in others. The rufous 

 submarginal spots of the primaries also vary in distinctness.
