_Upper Side._ Antennæ brown. Head black, with eight whiteish spots on the top. Thorax black, with four white spots at the base of the anterior wings. Abdomen black at the base and at top, clay-coloured on the sides and extremity. Anterior wings black at the base, but at the extremities more of a brown colour, with eighteen different shaped marks and spots; those next the body dark orange, the others yellow clay-coloured, some being so faint as to be hardly discernible. Posterior wings slightly dentated, the inner scollops being edged with clay-coloured crescents. These wings, next the body, are of a dark orange; the remainder clay-coloured, with a broad black border running round each wing, from the upper corners to the abdominal ones; the inner sides being deeply indented, and the outer ones scolloped, with eight roundish black spots near the middle of each wing, one of which is supposed to be hid in the figure. _Under Side._ Head black, with two white spots in front. Palpi scarcely discernible. Breast and sides black, spotted with yellow. Abdomen clay-coloured. The middle of the superior wings has a black patch, on which are three orange-coloured spots, answering to three on the upper side; a long angular dark orange mark joins the anterior edges next the body, close to which are two roundish black spots; the extreme parts of these wings are of a dark greyish ash colour, the ribs being black. Posterior wings clay-coloured, with eight black spots, answering to those on the upper side: the black border being narrower on this side, and the inner edges much deeper indented. {2}This magnificent butterfly is so exceedingly rare that M. Boisduval, whose knowledge of the European Collections is very extensive, questions whether there exists any other specimen than that originally figured by Drury. Mr. Jones also, whose splendid Collection of Drawings are so frequently quoted by Fabricius, copied this insect, figuring both the upper and under sides, which figures have been lately published by Mr. Donovan in his Naturalist's Repository. Mr. Donovan also adds, that from the manuscripts of Mr. Drury, "we find that he received this insect in 1775, from Mr. Smeathman, an assiduous and very intelligent naturalist stationed at Sierra Leone."
