Male. Wings above pearly white. Anterior wings with the costal and outer margins fuscous, inwardly 

 and broadly margined with pale resplendent bluish, which colour also occupies the whole base of wing, 

 and leaves the pearly white ground-colour as an oblique fascia, commencing at the upper discoidal nervule, 

 and suddenly narrowing beneath the second median nervule. Posterior wings with the posterior margin 

 fuscous, inwardly broadly and irregularly margined with pale resplendent bluish, which colour also occupies 

 base of wing. 



Wings beneath pearly white, sometimes with bluish reflections, and outwardly tinged with pale 

 ochraceous. Anterior wings with the costal and outer margins narrowly fuscous, and with the following 

 markings of the same colour, viz. : — two oblique fascite near base, a short subapical fascia extending from 

 costa to a little beneath lower discoidal nervule, a rounded spot on second median nervule, a broad short 

 fascia extending from second median nervule to near inner margin, and two marginal series of spots placed 

 between the nervules. Posterior wings with the following fuscous markings : — two short oblique basal 

 fasciae, a short transverse fascia extending from abdominal margin to second median nervule, a similar 

 central one placed nearer margin, a short curved fascia near apex and two marginal series of spots placed 

 between the nervules. Body above blackish, beneath more or less concolorous with wings ; legs fuscous, 

 with white markings ; antenna fuscous, annulated with greyish. 



Female. Eesembling the male, but without the resplendent blue coloration above.

The habitats given above, though few in number, are still sufficient to show that this 

 species is somewhat widely distributed.
