Habitat: Sierra Leone.

Upper Side. Antennæ brown. Thorax and abdomen nearly black. Wings white; margined externally with dusky black. The anterior edges of the anterior ones are also margined with black, from the middle of which runs a black line to a round spot placed on the middle of the wings; the mixture of the colours on these wings somewhat resembles the profile of a human face. Posterior wings having a round spot placed near the middle of each, with several fainter ones along the external edges, and two stronger ones near the upper corners.

Under Side. Palpi and legs black. Breast ash-coloured. Anterior wings as on the upper side; three oblong yellow spots being placed at the tips, and four round white ones along the external edges. Posterior wings much tinged with yellow, having a yellow margin running from the abdominal to the upper corners along the external edges, appearing like crescents placed on a row; above this is a row of seven square black spots placed circularly with the margin, and in the centre is a conspicuous round black spot.

Mr. Smeathman states that this insect loves chiefly to sport in the sunshine. It is therefore very difficult to catch at that time of the day when the sun is powerful; but towards sunset it is more easily caught, when it congregates in great numbers, in particular spots most sheltered from the breeze.
