This very distinct species has the wings on the upper side of a buff colour, varying from dull orange to reddish; the black spots are of small size, and the fore wings have the apex broadly and triangularly black, whilst the hind wings have the slender apical outer black margin preceded by a series of slender depressed black arches enclosing spots of the ground colour of the wing; the ordinary black spot in the middle of the discoidal cell is sometimes preceded by a smaller, more or less slightly marked, dot, behind which is another small one; the cell is partially closed by a small oblique black spot, followed at some distance by a row of four small spots placed obliquely, and there are two other small spots between the middle of the wing and the posterior angle, the outer one being occasionally duplicated; in the hind wings the black spots, about twelve in number, are of nearly uniform small size. On the under side the black apex of the upper side is replaced by the ground colour of the rest of the wing, the spaces between the veins being more strongly marked with orange stripes: the hind wings are buff-coloured, with the spaces between the veins in the basal portion marked with red, having the black dots (about twenty in number) surrounded with buff, whilst in the apical half of the wing the intervening spaces are more orange; the black arcade preceding the slender outer black edging is marked more distinctly than on the upper side. The head and body are spotted as in the preceding species. 38. (8) ACRÆA NATALICA, Boisduval in Delegorgue’s Voy. Afr.

A series of small specimens, measuring only 2 inches in expanse of the fore wings, were taken at Tati. A large specimen (2¾ inches expanse) was taken near the Dry River in the beginning of March, and one (2½ inches expanse) was taken near the Motloutsi River in August. 39.
