[May 1 , descends slightly inwardly a transverse narrow dark fascia, becoming forked at the tornus; beyond this fascia the terminal area of the wing is fuscous with a white transverse dorsal patch divided by a dark line; cilia whitish tipped with blackish, with a blackish line near their base, followed by twro obscure lines which coalesce and vanish at the position where a white subapical spot interrupts the dark tips of the cilia (in really fine specimens it would seem that the extreme tips of the cilia would be white). Exp. al. 15 mm. Ilindwings appearing dark cinereous (but actually blackish tessellated with whitish); cilia cinereous, with a dark dividing-line near their base. Abdomen cinereous. Legs whitish, the tarsi with blackish bands externally. Type 2 • Hab. T ibet , Gyantze, 13,000 ft., vi. 1904 (H. J. Walton, Tibet Expedition 1905 : 172). Unique. 227. T ortrix L. T ortrix sp. Hab.

Two specimens belonging to the Siberian and Central Asian form distributed by Staudinger as var. plumbeana. As this melanic form is quite recognisable, it will be well to refer to it under this varietal name, describing it briefly as plumbeous irro-rated with white, the white scales tending to be more distinctly noticeable between the veins, along the fold and on the cell, but in most specimens no such attempt at white markings is to be observed ; the hind wings are cinereous or plumbeous.
