31. (1) ACRÆA ATERGATIS, Westw. (Plate F, figs. 1, 2.) Alis supra rufo-aurantiis, nigro-maculatis, anticis apice nigro et sub apicem nigro-lineatis margine apicali omnium nigro. Expansio alar. antic. unc. 2¹⁄₁₂. Habitat prope “Victoria Falls;” mense Januario capta. The upper side of the wings is of a rich orange-red colour, the base of all the wings slightly powdered with black atoms; a black spot is placed in the middle of the cell of the fore wings, followed by a smaller transverse one at the extremity of the cell; at a little distance beyond the cell is a short black, rather oblique fascia, formed of five more or less confluent spots, the innermost being incurved and placed between the 2d and 3d branches of the median vein; this last spot is succeeded by two other spots, the three being parallel with the apical margin of the wing; there is also a minute round dot towards the base of the wing behind the basal part of the median vein, and two small dots near the inner angle; the veins are black in the apical part of the wing, with the interstices between the veins marked with thin black lines, the margin itself as well as the apex of the wing being also black; the hind wings are marked with twelve round black spots; the six outer ones arranged in a very waved line; the margin is also black. On the under side the fore wings are of a more rosy tint, except towards the apex, where they are more orange; the spots of the upper side are here reproduced: the hind wings on this side are more variegated; the black spots are more numerous, being about 18 in number, several close to the base of the wing being visible, which are not seen on the upper side; the spots are placed on pale greyish buff spaces, which gives them an ocellated appearance; and the outer margin of the wing is pale greyish buff with a very thin black marginal line, preceded by very thin black lunules, the veins rather thickened and black along the margin, the spaces between the veins being rosy red in the part of the wing between the terminal row of spots and the lunules. Antennæ black; palpi fulvous, with the last joint black; body black, spotted with white and rose-colour; legs fulvous, tarsi black; abdomen, above black with thin yellowish edges to the segments, each of which has two fulvous spots, beneath fulvous with two rows of black specks.
