Show 1891.] BUTTERFLIES FROM EASTERN AFRICA. 635 Underside.-Fore wing. Basal area rufous, paler along the inner margin, the patch of orange on the upperside being decidedly lighter below. Costa black as far as the apical patch above the discoidal cell, which then becomes more indistinct and very much dentated towards the inner margin. The hind margin is edged with a narrow border of orange-yellow which extends in thin rays between the nervules, each nervule being distinctly marked with black, and having a black ground with a line of yellow on either side of the nervules, Hind wing. Base of wing yellow, with a narrow transverse band of deep rufous extending from the costa to the inner margin and spreading up to the base. This transverse band is outlined on either side with small black spots, which become more numerous at the inner margin. Middle portion of wing pale yellow, followed by a submarginal border of eight nervules, black, with a streak of vellow on both sides and then outlined with black. Between each of these nervules is a streak of orange-yellow ; also at the very edge of the wing are seven triangular-shaped spots of pale yellow, the last spot (counting from the costa) being the smallest. Expanse 1*8 inch. Hab. Sotik, Kavirondo, Oct. 1889. Genus PLANEMA. PLANEMA LATIFASCIATA, sp. n. (Plate XLVIII. fig. 6.) Nearest to P. euryta, Linn., but is easily distinguished by the deep chestnut-colour at the base of the fore wing and by being so much smaller in size. Fore wing. Base and greater part of basal area deep rufous brown or chestnut, edged with a narrow outline of black, which is very strongly dentated below the discoidal cell, becoming almost invisible towards the inner margin. Across the middle of the wing is a band of deep orange-yellow, much dentated externally on the first, second, and third median nervules; this band becoming much narrower at the inner margin. A large portion of the apex black or very dark brown, which colour continues along the hind margin, though decreasing very much in width towards the inner margin. Hind wing. Rufous base much more restricted than in the fore wing, though somewhat lighter than in the latter. A transverse band of pale cream-colour or yellow crosses the middle of the wing, increasing slightly in width to the inner margin. This band is followed by a very broad border of black or deep brown along the hind margin, this colour extending along the nervules, while there are also internervular rays of the same colour reaching to about the middle of the transverse band. There are a few black spots at the base. Underside. Very similar to the upperside, though the fore wing is much lighter in colour. Hind wing. Base as dark as that in the fore wing, having two small black spots above the cell, one in the middle, and a streak or |
