of the second branch and that of the discoidal nerviile scarcely differs at all throughout the 

 subfamily ; and throughout the subfamily also the second and third median nervules are emit- 

 ted close together at the apex of the cell. 



Of the five Indian species placed in this genus, three f'Z?. csa/;a, D. patna and D. vasudcva) 

 were included in it by Mr. Butler ; one, D. singhala, subsequently described, was classed by 

 Mr. Moore as an Elymnias, and one, D. peali, has only just been discovered. The two latter 

 would seem from their outline and markings to belong to Elymnias ; D. singhala is identical 

 in outline with E. liilescens, and only differs from it in having the pale band on the upperside 

 composed of partially confluent strice and without black submarginal spots, and the underside 

 with the ocelli minute and obsolescent ; and D. pcali is identical in outline with E. iitiiandta ; 

 but both D. singhala and D. pcali have the cell of the hindwing formed as in Dyctis, The 

 remaining three species have the outline much more even, as in the typical species from the 

 Austro-Malayan region. D. esaka is the most typical ; D. vasndeia somewhat less so, but 

 remarkable from its colouration which mimics some species of Delias or other dark Picris with 

 a large patch of white on the hindwing ; D. patna has the outer margin distinctly, though 

 feebly, dentate, and mimics an Euplaa of the superba type in colouration. 



As far as the females are known they are but little differentiated, ^^hereas in many 

 of the species of Elymnias the females differ very considerably in colour and markings 

 from the males.

B. Hindwing with the lower disco-cellular nervule straight or feebly concave. 



a. The upper disco-cellular suberect or outwardly oblique, almost in the same line as the lower. 



a*. Forewing elongate ; outer margin irregularly dentate and distinctly falcate ; hindwing

268. D. SINGHALA, Ceylon. 



c*. Forewing elongate, but broad; outer margin of both wings even, regularly but not 



very prominently dentate ; (outline as in E. leucocyiita, but the wings much broader 



and inner margin longer).

 of hindwing being both equal to the costa of forewing.
