and is cut short by vein 8, the postmedian band starts from the apical fourth of 

 vein 1 b and is continued in an almost regular zigzag to the apex of vein 6 ; there is a 

 pale spot near the base of cell 7.

Distinguished from Halpe by the secondary sexual characters on the underside of the 

 fore wing in the male, which consist of a thickening of the basal part of vein 2 and a 

 portion of the lower edge of the cell near it, so as to form a swollen <, which is partly 

 covered by a thick tuft of long black hairs springing from the dorsum near the base. 



Three species are known to us, and may be distinguished as follows : — 



1 (4). Male. Hind wing : vein 8 and the upper edge of the cell normal. 



2 (3). Cell-spot on the fore wing geminate; hind wing below with "five un- 



defined brown spots" (de Nicev.) abima, Hew. 



3 (2). One moderately large spot next the lower edge of the cell on the fore 



wing, sometimes with another punctiform one just above it. Hind 

 wing below brown, more or less closely covered with greyish-yellow 

 scales, except on a large spot near the end of the cell and a triangular 

 postmedian spot ; the base of this brown triangle occupies about the 

 basal half of vein 2, and its apex just reaches vein 6 angulifera, n. sp. 



4 (1). Male. Hind wing: vein 8 and the upper edge of the cell forming a 



" tuning-fork " at their junction; upperside with a small oval oblique 

 streak close to the base ; underside dark reddish brown, immaculate, 

 "frosted over with scattered golden-yellow scales" grasa, de Nicev.

6 . Upperside brown : fore wing with four or five sordid yellowish-white spots 

 placed as follows : — one near the apex of the lower edge of the cell, sometimes with a 

 punctiform one just above it, one about twice as high as wide in cell 2, one roundish 

 or subquadrate near the basal third of cell 3, and one small and roundish in cell 6. 

 Underside : fore wing as on the upperside, but paler along the dorsum, and with the
