Type, P. truncata, Hufn. POLYPHASIA ALBISERIATA, sp. n. tf ?. Fore wings velvety blackish, dusted, especially towards the hind margin,with very fine golden-yellow scales; lines irregularly zigzag, consisting of lilac-grey scales ; 1st at ^; 2nd, forming the inner edge of the central fascia, at ^, running in just below the middle into the fascia; 3rd at |, limiting the central fascia externally, contains 2 more prominent denticulations, one subcostal, the other at the middle; down the centre of the central fascia, beginning at the costa, runs a series of contiguous oval white spots, which does not reach the inner margin; submarginal line slender, undulating, pale golden; fringes dark fuscous, with a deep black line at base, interrupted at the end of each vein by a lilac-grey wedge-shaped spot. Hind wings smooth, fuscous, with the inner angle including the fringes clear white; rest of the fringes dark fuscous, preceded by a deep black line; traces of an undulating submarginal line edged with paler are visible towards the costa. Head and thorax velvety blackish; abdomen blackish, dusted with paler scales between the segmental divisions. Underside of fore wings rather glossy grey, paler towards the costa in the disk, and with a white apical patch ; the line bounding the central fascia on the outside, and the discal spot, darker. Hind wings glossy whitish for f from base ; a distinct dark grey exterior line, followed by a diffuse, blotched shade, and dark fuscous fringes ; apex of the wings broadly white. Expanse of wings 46 millim. In the 2 the series of white spots in the central fascia is reduced to 3, and the whole submarginal area of both wings on the underside is whitish. Hab. Sikkim. [This distinct species seems common on the Sundukpho range at about 11,000-12,000 feet. It varies in the size of the white spots on the fore wing, which are sometimes almost obsolete.- H. J. E.] POLYPHASIA ALBIANGULATA, sp. n. 3 2 • Fore wings dark fuscous or blackish, interspersed with deep tawny, the latter tints forming a more or less distinctly expressed fascia on either side of the central fascia ; basal patch dark, edged in its lower half, finely but obscurely, with whitish; central fascia edged with a very strongly-marked, acutely biangulated thick white line, which in its upper half is internally irregularly dentate, and which ends on the inner margin with an outward curve ; from the costa, in the centre of the central fascia runs a thick white line parallel to the upper arm, and not quite reaching the lower arm of the |
