of the wing; discocellulars oblique, of equal length, vein 6 from upper end of the cell, 
5 from the middle of discocellulars, 3 from very near the lower end, 2 from the middle,

Imago. —Male. Upperside blue-black. Forewing with the outer margin very 
broadly black, the blue merging into the black, but in certain lights a broad even 
black outer marginal band occupying a third of the wing is visible. Hindwing with 
the basal and abdominal areas pale, in certain lights there is a black streak below the 
basal area and another on the outer side of the abdominal area, and on the veins; tail 
black, tipped with white ; terminal line black. Cilia black, except between the tail 
and the anal lobe, where it is white, tipped with black. Underside grey, markings a 
little darker than the ground colour, edged with white. Forewing with a line closing 
the cell, a discal, slightly outwardly curved line of lunules from near the costa to below 
the sub-median vein. Hindwing with a thin bar across the end of the cell, a discal 
band of thicker lunules passing close outside the cell bar, the third lunule outside the 
others, the lower portion of the series indented and curving inwards to the abdominal 
margin ; a double sub-marginal series of small lunular marks, all capped with bluish- 
white, a black anal spot, a larger one in the first interspace, both capped with pale 
orange, a pale orange line between them; terminal line on both wings black, with a 
white inner thread on the lower half of the hindwing. Antennse black, ringed with 
white; head and body above concolorous with the wings, white below.
