ON THE LEPIDOPTERA OF THE TIBET COMMISSION. [May 1, 



descends slightly inwardly a transverse narrow dark fascia, 

 becoming foi'ked 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 two 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), 

 Exf. al. 15 mm. Hinchoings 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.

Two specimens belonging to the Siberian and Centi-al Asian 

 form distributed by Staudinger as var. plumheana. 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.
