Show 140 LT.-COL. J. MALCOLM FAWCETT ON [ June 7, outer margin broadly black, irregularly dentate on nervules on its inner edge, with the following sulphur-yellow spots, viz., five forming a curved row near the apex from costa to 3rd median nervule, the lower two being larger than the upper three; also one spot between the 1st and 2nd median nervules, and one between the 1st median nervule and the submedian nervure; cilia of both wings whitish with a pink suffusion. Hind wing black, basally thickly irrorated with sulphur atoms; an orange spot at end of cell; anal and outer margin sulphur-yellow, which forms into a line of lunular spots on outer margin. Body black, head and antennae pink. Under side : fore wing-disk pale yellow ; apex and outer margin grass-green, with a submarginal line of pale yellow spots ; a black spot at apex of cell, and three black discal spots in a row between the median nervules and submedian nervure. Hind wing grass-green, paler on outer margin, and irrorated with black atoms; a silver spot sin-rounded by a pink area at the apex of the cell. This species belongs to the hyale section of the genus Colias, and is nearest to C. erschojfi Alplieraky, from the Tian Shan Mts. 9. C o lias n in a . (Plate IX. fig. 9.) Colias nina Fawcett, Abstr.

Upper side : fore wing pale sulphur-yellow, the disc below the median nervure and 3rd median nervule orange; a black diamond-shaped spot at apex of cell; a broad black outer marginal band, inwardly irregularly dentate on the nervules, irrorated with sulphur-yellow scales outwardly, and a submarginal row of ill-defined sulphur spots between the nervules, that between the 2nd and 3rd median nervules being obsolete. Hind wing black, irrorated with pale sulphur atoms, most thickly towards the base and outer margin; discoidal cell pale yellow, with an orange spot at its apex; a submarginal row of pale sulphur hastate spots ; antennae and cilia pinkish. Under side : fore wing-disk as on upper side; apex and outer margin pale green, irrorated with black atoms; a black spot at apex of cell, and three or four ill-defined black spots discally between the nervules. Hind wing pale green, with spots as on upper side. This species appears to be a transition between the hyale and edasa sections of Colias. 10. C o lias eogene Felder, var. l e e c h i Gr.-Gr.
