The species are numbered in what would appear to be their most 

 natural order. The females of all the species have vein 3 of the 

 fore wing close to the end of the cell, as in the last group of the 

 males. 



This genus is confined to the Oriental region, China anl Japan. 



ISMENE ATAPHUS, U. Sp. 



Ismene oedipodea, Moore (nee Swainson), Lep. Ceyl. vol. i. p. 158, 

 pi. 64. figs. 2, 2 a, 2 6 (1881). 



This species is the Indian representative of the Suinatrau cedipodea, 

 with which it has hitherto been confounded. Tiie male differs 

 from that of oedipodea in the costal margin of the hiud wing being 

 normal, whereas in oedipodea the costal margin is folded over and 

 the costal vein is correlatively distorted. The female has a costal 

 red streak on the upperside of the fore wing which is entirely absent 

 in the female of cudipodea. Furthermore, in both sexes of oedipodea 

 the thorax and base of wings are conspicuously clothed with long 

 silvery greenish-blue scales; in ataphus this clothing is of a duller 

 green and of less extent, especially on the wings. The cilia of the 

 hind wings are also much longer and redder in ataphus than in 

 (v.dipodea.
