Black, exterior fringes of the wings white between the extremities 

 of the nervures. The hind wings dentate, crossed above by a broad 

 band of bright azure-blue, divided by the black nervures ; below tbe 

 azure band reduced to a series of blue lunules, tinged with red, ter-

 nervules ; beyond these a curved series of nine white spots from the 

 anterior margin to below the exterior angle, of which the three last
