Expanse, 6* 2$ 2 2| inches. Hab. Ceylon. In coll. F. M . Mackwood and F. Moore. Distinguished from the allied Ceylon species C. galene, Felder, Nov. Reise, p. 165, by the bright yellow colour of the underside. APPIAS TAPROBANA, n. sp. Differs from typical specimens of A. hippo, Cram. Pap. Exot. ii. pi. 1 95, f. B, C, from Sumatra, in its smaller size, the male having a darker and somewhat broader well-defined dentate marginal band above, the underside having the prominent apical spot and the hind wing of darker yellow, the band being quite as broad, the costal vein narrowly and the subcostal broadly speckled with dark brown.

Hab. Ceylon. In coll. F. M . Mackwood and F. Moore. PAPILIONINvE. P A P I L I O CASYAPA, n. sp. From Himalayan specimens of P. panope, Linn. (Cram. Pap. Exot. iv. pi. 295. f. E, F ) , this differs in the male being of a darker purple brown, and the female darkest-coloured on the fore wing basally between the veins. The fore wings in both sexes have a third or inner discal series of speckled dentate marks on both upper and undersides, these being most prominent in the female; hind wing with well-defined and broad markings. Expanse 4^ inches. Hab. Calcutta district (Russell and Farr.). In coll. F. Moore. PAPILIO LANKESWARA, n. sp. Distinguished from P. panope and P. clytia by its much paler colour, the fore wing having the veins broadly and the outer border pale coffee-brown, the basal interspaces between the veins only being dusky black; the marginal spots are very small, the upper series being obsolete in the male and indistinct in the female; hind wing with the discal dentate marks less distinct, shorter and widely separated from the submarginal narrow dentate lunules, marginal lunules broadest in the male. Expanse 4 inches. Hab. Ceylon. In coll. F. M . Mackwood and F. Moore. This is certainly not P. lacedeemon, Fabr. It does not agree either with the description or with Donovan's figure. |
