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.
