 towards anal angle ; no discal band to hindwing. 

 «". Macular band pale yellow. 



490. E. PATALA, Himalayas, Chumba to Nepal. 

 (5^. Macular band white or greenish-white.

 costa towards anal angle in each wing, 



495. E. SAHADEVA, Nepal, Sikkim, Assam. 



</'. Both wings with a continuous curved pure white discal band from middle of costa of 

 forewing to near first median nervule of hindwing. 



496. E. DURGA, Sikkim, Assam. 



The first five species have been generically separated from Eiithalia by Mr. Moore under 

 the name of Dophla* and have the discoidal cell of both wings closed. They are all large 

 insects, the forewing in several of them deeply emarginate below the apex, giving it a very 

 hooked appearance ; colouration above dark-brown or green, with two black sinuous fine lines 

 across the cell on the upperside of the forewing in the first four species, enclosing anteriorly a 

 crimson spot in three of them. One species (^E. derma) has been recorded from Masuri and 

 occurs in Assam, Sylhet and Malayana ; another {E. evelina) occurs in South India and Ceylon ; 

 there are two other species described by Felder from North India which appear to be but slight 

 varieties of these two species. Another very distinct species of this group {E. ditttya) has a 

 series of small but prominent whitish spots across the disc of both wings, and occurs in Lower 

 Tenasserim, Perak and Borneo. In this species the crimsom markings are barely traceable.
