Forewings : pale yellowish ochreous, the costal aud hindmarginal areas deeper 

 yellow ; the whole wing spangled with shining scales ; all the markings deep 

 ferrnginons ; two curved lines near base, the outer closely followed by the rather 

 large cell-spot, beyond which comes a thick nearly straight line from costa just 

 before middle to before middle of inner margin ; beyond the middle a slightly 

 curved exterior line, lunulate-dentate, the teeth large and plain ; the veins in the 

 preceding space all ferruginous ; immediately beyond is a double submarginal line, 

 the inner arm dentate-lunulate, the outer thick, slightly indented at vein 4 and on 

 submedian fold ; a diti'use marginal line, joined by ferruginous dashes between the 

 veins ; fringe yellow, slenderly mottled with fuscous.

Subfamily ASCOTlNAE. 

 22. Alcis ansorgei sp. nov. 



Forewings : pale grey, speckled with darker, and tinged in parts with brownish ; 

 the lines thick, brown-black ; the first near base from one-fifth of costa to one-fourth 

 of inner margin, hardly curved, but toothed outwards on median and submedian 

 veins ; outer line from nearly three-fourths of costa to two-thirds of inner margin, 

 oblique inwards parallel to hindmargin as far as vein 6, then bent outwards to 

 vein 5, and again obliquely curved inwards, thickened at base of veins 3 and 4, 

 where it touches an augulated cell-mark, and toothed ontwards on the veins, 

 especially on the submedian. This line is followed, as the first is preceded, by a 

 thick umber-brown shade, most marked at costa ; a faintly indicated median line 

 starting from a conspicuous central costal spot, and traversing the upper jiart of the 

 black angulated cell-spot; sulimarginal line pale, lunulate, the lunnles beyond cell 

 and beneath costa more filled up with dark scales ; a marginal row of black spots ; 

 fringe grey, irregularly tinged with darker. The central area, especially the outer 

 upper portion, is paler than either the basal or marginal area. 



Himhriugs : with an antemeJian shade, distinct only towards inner margin, a 

 blackish dentate postmedian line, followed, as in forewings, by a brown shade ; the 

 submarginal line obscure ; a dark diffuse cell-spot. 



Underside ochreous grey, speckled with fuscous, the markings showing 

 through. Head, thorax, and abdomen coucolorous with wings ; face and paljii 

 brown. 



Expanse of wings : 42 mm.
