This pretty little species appears to be undescribed. It is nearly allied to _C. Etrida_ and _Eione_, but differs in its characteristic markings. On the upper side the wings of the male are white, with a very slight yellowish tinge; the anterior have a large brown patch occupying the greater portion of the posterior margin, and extending over the greater part of the discoidal cell, at the extremity of which is a small round black spot; the extremity of the wing is very broadly brown, the dark colour commencing on the costal margin in front of the discoidal spot, and extending nearly to the posterior angle of the wing, where it is much narrowed, especially in the spaces between the anal vein and the first and second branches of the median vein, extending considerably more forward between the second and third branches of the latter, so as nearly to unite with the truncated extremity of the large brown patch; the brown apex of the wing bears a row of five fulvous oval spots, the hind one of which is ill defined and less strongly coloured: the hind wings are brown at the base, and beyond the middle they are marked with a curved irregular brown bar, which is partially connected with the brown spotted hind margin of the wing, having a row of white spots between them, which become larger and more or less confluent, especially towards the anal angle. On the under side the fore wings are tinged with yellow, especially towards the tips, the large brown markings of the upper side being nearly obsolete: the hind wings are also yellowish, with a faint dusky fascia beyond the middle, with a black discoidal spot surmounted with yellow scales; the costa at the base is bright yellow, and the fringe of all the wings is white. The female is slightly larger, with the brown markings more suffused, the orange spots of the fore wings obsolete, and replaced by brown, and the white submarginal spots of the hind wings almost obliterated and replaced with brown.
