DELIAS. 143 



postdiscal transverse fascia as on the upperside oblique but broader. 

 Hind wing differs from that of eucharis in the much deeper 

 chrome-yellow tint of the ground-colour, the postdiscal black 

 curved fascia that in eucharis separates the yellow from the 

 subtenninal vermilion-red spots entirely wanting, the red spots 

 themselves pointed inwardly, not subcordate, they conspicuously 

 increase in size posteriorly. Antennae, head, thorax and abdomen 

 similar to those of eucharis. $ differs from the 2 of eucharis on 

 the upperside by the very much darker shading, especially on the 

 fore wing, and by the postdiscal transverse band which is as in the 

 d oblique but broader. Hind wing also more darkly shaded, the 

 postdiscal transverse curved black baud entirely absent. Underside 

 as in the $ but darker, the fore wing especially more thickly 

 shaded with black scaling, the preapical interspaces tinged with 

 yellow. Antennae, thorax and abdomen similar to those in eucharis. 



Exp. d $ 78-84 mm. (3-08-3-30"). 



Hab. The Himalayas from Kumaon to Sikhim in the low 

 hot valleys ; Bengal ; Calcutta (de Niceville) ; Assam ; Burma to 

 Northern Teuasseriin ; extending to Siam. 



Specimens from the Himalayas and Assam are paler than Burmese 

 specimens and have the yellow on the underside of the hind wing 

 often restricted to the base and to the posterior half of the wing. 



Race metarete, Butler. Differs from typical Jiierta as follows : 

 d . Upperside . ground-colour a much purer white ; apical half of 

 fore wing in contrast with the white on basal half densely shaded 

 with black scales. Underside : the colours clearer and purer, the 

 chrome-yellow on the hind wing confined to the base and posterior 

 half of the wing, the apical half of the cell and the anterior inter- 

 spaces within the line of the vermiliou-red spots pure white ; the 

 anterior two or three subterminal red spots margined interiorly 

 with diffuse black scaling. $ differs less from the 2 of hierta, 

 but on the underside of the hind wing the yellow colour is as 

 restricted as it is in the d ; the subterrninal red spots are of a 

 richer vermilion than in hierta, and the anterior two or three as 

 in the d have an interior narrow margin of diffuse black scales. 

 Antennae, head, thorax and abdomen as in hierta, but the thorax 

 and abdomen shaded slightly darker with a bluish-grey appearance. 



Exp. d $ 76-88 mm. (3-02-3-48"). 



Nab. Southern Tenasserim ; extending to Malacca and Sumatra. 



Race ethire, Doherfy. d $ . Differs from typical hierta as 

 follows: d- Upperside: very pure white. Fore wing : the black 

 margins to the veins very narrow, the oblique postdiscal band ill- 

 defined, scarcely any irroratiou of black scales on the apical half of 

 the wing. Hind wing pure white, the colours of the underside 

 seen through by transparency as in hierta. Underside : differs 

 from hierta principally in the brighter tint of the yellow on the 

 hind wing, and in the more clearly defined, less diffuse black 

 margins of the veins. 5 . Differs less from 2 hierta than does
