88. Delias hierta- — male and female closely resemble D. eucharis, but can be 

 distinguished as follows : — male upperside : fore wing : the black margins to 

 the veins more diflFuse ; the transverse, postdiscal fascia diffuse, ill-defined, 

 oblique, not parallel to termen in its lower portion but terminated at apex 

 of vein 2 ; the apical portion of the wing beyond the fascia more or less so 

 thickly shaded with black scales as to leave the white lanceolate spaces 

 between the veins (so prominent in eucharis) ill-defined and obscure. Hind 

 wing white, the black venation and terminal narrows, black border as well as 

 the subterminal vermilion-red spots between the veins on the underside 

 show through by transparency. Underside : fore wing as in eucharis, but 

 the back margins to the veins much broader and the postdiscal, transverse 

 fascia as on the upperside, oblique but broader. Hind wing differs from 

 that of euchaiis in the much deeper chrome-yellow tint of the ground- 

 colour, the postdiscal, black, curved fascia that in eucharis separates the 

 yellow from the subterminal 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. Female differs from the female of euchaiis on the upper- 

 side by the very much darker shading, especially on the f orewmg and by the 

 postdiscal, transverse band which is as in the male oblique but broader. 

 Hind wing also more darkly shaded, the postdiscal, transverse, curved, 

 Wack band entirely absent. Underside as in the male but darker, the fore- 

 wing especially more thickly shaded with black scaling, the preapical inter- 

 spaces tinged with yellow. Antennae, thorax and abdomen similar to those 

 in eucharis. Expanse : 78-84mm. 



Habits. — As far as is known the species lias not been bred. 

 ■Specimens from the Himalayas are said to be paler than those 

 from Burma and have the yellow on hind wing on the underside 

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

 There are two very nearly allied races or species called D. oneta- 

 rete and ethira from Southern Tenasserim and Madras ; Orissa ; 

 Lower Bengal, respectively. D. hierta exists in the Himalayas 

 from Kumaon to Sikhim in the low, hot valleys ; Bengal ; Calcutta 

 (de Nice'ville) ; Assam ; Burma to Northern Tenasserim ; extending 

 to Siam. The larva of another species from Nepal, Sikhim, 

 Assam, Burma, Tenasserim, extending to the Malay Peninsula 

 and Borneo and, on the east, to South China, namely, D. aglaia, is, 

 from the description, probably \e,Tj similar to that of our B. 

 eucharis ; but is said to feed upon Nauclea rotundifolia a species 

 belonging to the family Ruhiacece.
