Imago. — Male. Upperside greyish silvery-blue, with some darker glistening blue 

 scales at the base ; the tint of colour is quite different to that of strabo, the markings 

 above and below are, however, very similar, but the sub-anal black spot on the hindwing 

 is seldom capped with orange, the cilia of that wing has black points at the vein ends, 

 and there is a distinct sub-terminal series of blackish lunules. Also on the underside 

 of the forewing, the sub-costal small spot above the discal band, in every example we 

 have examined, is closer to the band, very nearly touching the uppermost spot of the 

 band, whereas in strabo it is always widely separated from it ; the genitalia, however, 

 is very similar to that of strabo, but there is some difference in the androconia. 



Female. With the same peculiar silvery blue scaling above, the sub-anal spot 

 sometimes (but not always) capped with pale orange ; markings similar. 



Expanse of wings, $ ? 1-^ inches. 



Habitat. — Assam, Ceylon, Andamans and the Malayan sub-region. 



Distribution. — Moore records it from Ceylon, Elwes from Burma, de Niceville 

 from the Philippines ; we have a fine series from the Khasia Hills, Port Blair and 

 Amboina.
