Upperside: forewing black with the following bluish-grey markings: a very slender line along costal margin, a broad streak from base in cell that does not reach the apex of the same, two spots on the black area at apex, a long streak in interspace la; two elongate broad streaks in interspace 1 divided by a slender black ill-defined line; broad rectangular streaks in interspaces 2, 3, 4 and 6; a narrower inwardly obsolescent streak in interspace 5, and elongate spots in interspaces 8, 9, and 10; the streaks in interspaces 1 to 4 crossed transversely near their apices by a line of the ground colour; finally a complete subterminal series of small whitish spots.
Hindwing rich chestnut red; cell filled by a trifid bluish - grey streak, followed at the bases of interspaces 2 to 6 by elougate bluish-grey spots; a narrow streak of the same colour from base in interspace 1; a postdiscal series of spots in interspaces 5, 6 and 7 and a more or less obsolescent subterminal series of dots also bluish grey; the veins on the wing conspicuously paler than the ground colour.
Underside: forewing similar to the upperside except that the ground colour on the apical area is dull brown not black.
Hindwing also as the upperside, but the ground colour on the disc of the wing of a darker deeper shade of chestnut; the postdiscal series of spots more or less obscurely complete from interspace 1 to 7; and the subterminal series of spots of the upperside formed into lunules.
Antennae, head, thorax and abdomen black, the head and thorax variegated with bluish-grey spots, the abdomen with lateral transverse bars.

Race govindra, Moore very closely resembles the typical form but can always be distinguished by the presence of a complete series of postdiscal bluish-grey spots on the upperside of the hindwing.
It is generally also smaller in both sexes than typical agestor, and on the upperside of the hindwing the ground colour in the anterior interspaces is broadly centred along the middle with very dark brown, almost black.
The female frequently has the ground colour of the hindwing a much brighter chestnut (almost ochraceous) than in any specimen of female of agestor that the describer had seen.
