Alis rosaceis extus fusco indistincte limbatis ; anticis fascia transversa subapicali pallide rosacea et maculis novem nigris notatis, una cellulari, altera adfinem ejus, quatuor in linea arcuata ultra earn, duabus inter ramos medianos ad angulum analem et una inter venas medianam et submedianam ; posticis ad basin nigro maculatis et fascia macularum octo nigrarum margini externo subparallela notatis ; subtus ut supra, alis inter venas ad mar-ginem externum rubro notatis. Antennis nigris, palpis rosaceis apice nigro ; thorace et prothorace fuscis rosaceo notatis, abdo-mine supra medialiter fusco. Exp. 2*2 inches. 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 pervades the transverse subapical light spot of the primaries, so that it is hardly to be distinguished from the other markings of the wing. 9. ACR^A CECILIA. Papilio ceecilia, 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. ACR,EA CALYCE, sp. n. (Plate XVII. figs. 1, 2.) cS. Alis rosaceis, anticis interdum fuscis sed area apicali interna semper semihyalina; macula cellulari, aliis tribus (una ad cellules finem duabus infra earn in linea transversapositis) et quatuor ultra cellulam nigris ; posticis dense (pracipue 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 dimidiopostico 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. W e 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. 11. ACRiEA PSEUDEGINA. Acraa pseudegina, Westw. Gen. Diurn. Lep. p. 531. Papilio egina, Stoll (nee Cram.), Suppl.
