The extent of this colour very variable ; in some specimens, on the fore wing it spreads irregularly outwards mainly along the costa and on the hind wing in the middle to the disc; in others, it covers the basal three-fourths of the wings, leaving a well-defined broad terminal margin of the ground-colour on the fore wing, and on the hind wing, broad costal, terminal and dorsal margins ; cilia conspicuously white.
Underside of fore wing is a clear, slightly brownish grey, paler along the costal and terminal margins ; a transverse, slightly lunular discocellular spot and a transverse series of six small discal spots black, all with slender white edgings, the discal series placed in a slight curve, the posterior three spots en echelon ; no terminal markings except an anticiliary dark line. Hind wing metallic green ; in many specimens faint traces of one or two subbasal spots, entirely absent in others ; a discocellular spot and a curved, transverse, discal series of from three to five spots, white ; terminal markings, with the exception of a slender anticiliary dark line, absent, as on the fore wing.
Antennae, head, thorax and abdomen brownish black, the shafts of the antennae ringed with white, the head, thorax and abdomen with some bluish pubescence ; beneath : the palpi, thorax and abdomen white, the palpi fringed anteriorly with stiff black hairs.
