(Plate XXX. fig. 19.) 3 2 • Fore wings with the dark spaces velvety, fuscous; the basal patch divided by a fine yellowish twice-curved line, and followed by an irregular yellowish, somewhat denticulated, nearly vertical, fascia traversed by a fine line; central fascia broadest in centre, where its outer edge forms two blunt lobes ; followed by a pale fascia traversed by a fine dark line, the inner half being sdvery white, the outer yellowish ; marginal space occupied by a subquadrate velvety-fuscous patch throughout the costal half, and becoming more or less yellowish below, with a fuscous anal blotch, and two smaller ones above it; submarginal line composed of distinct white spots, 4 in a line from the costa, a larger one wedge-shaped in the middle, and 4 smaller ones beneath, one on each of the smaller fuscous blotches, and 2 on the anal blotch ; an oblique silvery-white apical streak; fringes fuscous tinged with yellowish. Hind wings pearly white with a greyish tinge ; a dark basal fringe-line, and traces of the beginning of two dark lines at the anal angle. Face yellow; head, thorax, and abdomen fuscous. Hind wings dark grey, mottled with paler, with the submarginal white spots reproduced. Expanse of wings 24 millim. Hab. Sikkim. Although so very distinct in appearance, it is quite possible that this example may be only a remarkable variety of the variable P. variabilis, above described. [As I have four specimens all agreeing and no intermediate forms among m y long series of P. variabilis, I look on this as a perfectly good species. It occurs with the last at 10,000-13,000 feet, but seems much less common.-H. J. E.] PERIZOMA LACTEIGUTTATA, sp. n. (Plate XXX. fig. 16.) 3 2 • Fore wings bronzy fuscous, with the ordinary lines and markings represented by a series of snow-white spots, one in the centre near the base of the wing; a curved series of 5, representing the pale fascia which usually divides the basal patch; a similarly curved series of 7, representing the outer edge of the basal patch; an indistinct series of 7, the two costal ones the largest, forms the inner edge of the central fascia; a more distinct and curved series of 9 forming its outer edge, the first, third, and ninth being much larger than the rest; an irregular submarginal series of spots; and lastly a series of distinct roundish dots at base of fringes, the 2nd being pear-shaped, the 5th and 6th connected by a quadrate blotch ; the 8th enlarged upwards into an irregular blotch ; through the space representing the central fascia runs a series of white dots of which the 3 top ones alone are distinct; in the disk a large irregularly trilobed white spot, with a still larger one below it; the costal and inner marginal spots of all the series are the largest; fringes brown, chequered with white between the marginal white spots. The spots are not symmetrical on the right and left wings |
