1893.] SPECIES OE MOTHS TEOM ustdia. 42l 



parallel to the hind margin, one in the centre, the other halfway 

 to the hind margin ; central spot indistinct, absorbed by the 

 central line ; underside brownish cinereous, with the 2 lines dis- 

 tinct. Head, thorax, and abdomen smoky brown. 



One $ , rather smaller than P. separata. 



Hah. Upper Assam. 



I was at first inclined to refer this to P. separata as a dark variety, 

 but the differences, especially on the underside, appear too great. 



[A single specimen from Margarita, Tipper Assam, was taken 

 by Doherty in May. — E. J. E.] 



Alcis nigeaxbata, sp. n. 



cJ 2 • Tore wings white, thickly dusted with irregular dark 

 grey atoms, which become confluent towards the base and hind 

 margin, and render those parts altogether dark ; a dark blackish 

 linear cell-spot with a darkish costal blotch above it, sometimes 

 uniting with it ; subterminal line whitish, denticulated, traversing 

 the dark field of the hind margin, and edged internally by a blackish 

 denticulated line; no other line visible. Hind wings the same, 

 with the base scarcely darker, with the subterminal line similar, 

 and a trace along the abdominal margin of the commencement of 

 a geminated dark central band. Underside like upper, but gene- 

 rally duller. Head, thorax, and abdomen cinereous. 



Expanse of wings 30 millim. 



ITab. Sikkim. 



This species comes near A. granitaria, Moore, but the ground- 

 colour is whiter and the shading darker ; it also approaches aclmis- 

 saria, Guen., but is without any of the brownish and ochreous 

 tints of that species, besides being much paler. 



[Taken by myself at Tonglo in July and as high as 12,000 feet 

 on the Nepal frontier of Sikkim. — H. J. E.'}

2 . Fore wings glossy, pale grey, dusted with darker grey and 

 ochreous scales ; transverse lines indistinctly expressed, being more 

 or less interrupted ; base, costa, inner and hind margins darker, 

 more diffused with dark grey ; disk paler ; basal line hardly dis- 

 tinguishable ; in middle of costa a blackish blotch enclosing the 

 dark cell-spot, a double dark spot obliquely below it, and a similar 

 one on the inner margin, the three representing a central shade, 

 running parallel to the hind margin ; a denticulated blackish outer 

 line, more distinct on the inner margin, where it is edged with 

 ochreous scales ; space beyond to the hind margin dark grey, with 

 an irregularly sinuous pale subterminal line ; fringes mottled light 

 and dark grey, with a row of black spots at the base between the 

 veins. Hind wings like fore wings, with a dark transverse line 

 near base, distinct only on inner margin ; a small black cell-spot 

 followed by two dark denticulated lines, the latter clearly edged 

 with pale grey. Head, thorax, and abdomen dark fuscous grey.
