Description
The ground colour is black. The markings are metallic blue. The blue band does not reach the hind wing margin in area 1b.Seitz-Only differs from Papilio charopus in that the median band of the upper surface is only a little widened posteriorly, so that the spots of cellules 2 and 8 of the hindwing cover but a third or a quarter of the cellules and are scarcely twice as long as broad; the submarginal spots of the hindwing beneath in the male yellow, very prominent, in the female as in charopus. — German East Africa.
