Hind wings entirely dark smoky fuscous. Head, thorax, and abdomen dark fuscous. Underside dull grey with some indistinctly waved shades. Expanse of wings 24 lnillirn. Hab. Sikkim; Naga Hills. This is a very indistinct looking and yet variable insect. Sometimes the suffusion only extends to the costal portion, leaving the inner margin of the wing pale ; in others it embraces the greater part of the wing. PERIZOMA, Hiib. Verz. p. 327. Emmelesia, Stph. 111. iii. p. 297. Type, P. albulata. PERIZOMA VARIABILIS, sp. n. (Plate XXX. fig. 17.) Fore wings greyish fuscous, with very indistinct transverse markings; basal patch darker, divided in the middle by a paler band, which is itself traversed by a thread-like line; and followed by a similar pale band separating it from the central fascia, which varies in width, and is also followed by a pale band like the other two; marginal area irregularly darker, in wdiich can be traced an indistinct submarginal line formed by a series of more or less distinct white dots or spots; sometimes 3 or 4 in a line from the costa, and 2 or 3 above the anal angle, but always one more clearly marked, in the middle, running in towards the base, and wedge-shaped ; fringes unicolorous ; the outline of the basal patch and central fascia varies, being sometimes curved, bluntly angulated, or acutely angulated; a distinct black cell-spot. In one varietal form the pale bands are decidedly greenish and more lustrous; in a second, the costal space beyond the central fascia is dull tawny; in a third, the submarginal spots are all distinct and the central one forms a large round white space. Hind wings of all the forms pearly-white, with a small dark cell-spot and a dark basal fringe line, and sometimes a fuscous or grey suffusion near the anal angle ; some specimens have only faint traces of a central curved line, others have the line distinct. Underside of both wings glossy grey, darker or lighter, with the markings of varying intensity. Head, thorax, and abdomen fuscous; face sometimes paler. Expanse of wings 22-26 millim. Eight examples, 4 3,4 $ , all from Tonglo, Sikkim. This variable species is slightly smaller on the average than P. affinis, Moore, and may be at once distinguished by the smooth glossy scaling and the lustrous paler spaces, especially along the inner margin of the fore wings. [A common species on the Nepal frontier from 10,000 to 13,000 feet in July.-H. J. E.~] |
