Brown, with a pale yellow streak at base of costa; an ovate spot of the same colour at the middle of the hind margin, and a short transverse band near apex of fore wing; hind wing with a long yellowish- brown streak in centre. Beneath, the same markings, but the streak of the hind wing is broader, connected with the costal margin near the middle ; fringes of both wings pale yellow. Thorax and head brown, with yellowish tegulae and spots on sides of neck. Abdomen banded with yellow above, beneath yellowish ; front of head and palpi yellow. Antennae pectinate, black. Expanse 21 m m. Described from a single specimen, taken by myself on the Singa-lelah range, dividing Sikkim and Nepal, at about 12,000 feet elevation, in July 1886. This species is most nearly allied to A. zebraica, which I have from Sikkim and Kulu. ARTONA ZEBRA, n. sp. (Plate XXXII. fig. 11,6*0 d . Brown, with a faint yellow costal streak ; 4 conspicuous yellow spots on fore wing, of which one at the base is elongate, the next two in the centre ovate, and the last near the apex geminate. Hind wing with a broad central longitudinal yellow patcb. Fringes broad, yellow, abruptly changing to brown close to the apex of the fore and hind wings, by which character it can readily be separated from the allied species. Beneath, the two central spots coalesce and touch the basal streaks; on the hind wing the yellow patch extends towards the abdominal margin. Tegulae and sides of neck, front of head, and base of coxae yellow. Abdomen brown, faintly banded with whitish ; end of abdomen below yellowish. Antennae black. Expanse 18 m m. Described from two males taken at the same time and place as the last, but lower down the mountain, at about 11,000 feet elevation. ARTONA POSTALBA, n. sp. (Plate XXXII. fig. 16, 6*.) With A. sikkimensis I took still another, which might be thought to be a variety of it, but which differs so conspicuously in the colour of the hind wings and fringes that, as I know of no similar variation in the species of this family, I must conclude to be a distinct species. It may be described shortly as like A. zebra, but with the central patch of the hind wing white instead of yellow, the fringes of the hind wings blackish instead of yellow, the costal streak at base of fore wing wanting. The tegulae show no yellow; the abdomen no whitish bands above, but narrow yellow bands below. Antennae black. Expanse 18 m m. |
