1879.] ASIATIC DIURNAL LEPIDOPTERA. 143 



Female. Similar above and beneath, excepting that the black 

 curved band on fore wing is twice the width, and the hind wing 

 having a submarginal macular fascia composed of black scales. 



Expanse, c? 2A 2 2| inches. 



Hab. Ceylon. In coll. F. M. xMackwood 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. J 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. 



Female. Above with broad well defined sinuous borders, the disk 

 of fore wing and basal area of hind wing broadly whitish, similar to 

 the female of A. vacuus ; underside as in male. 



Expanse 2-| inches. 



Hab. Ceylon. In coll. F. M. Mackwood and F. Moore. 



PaPILIONINjE. 



Papilio casyapa, n. sp. 



From Himalayan specimens of P. panope, Linn. (Cram. Pap. 

 Exot. iv, pi. 295. f. E, V), this differs in the male being of a darker 

 purple brown, and the female darkest-coloured on the fore wing 

 basally betweoi 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 sepa- 

 rated 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. lacedoemon, Fabr. It does not agree either 

 with the description or with Donovan's figure.
