This is a group of small dull-coloured species associated together on account of 

 their resemblance to the Thanaos stigmata of Moore. The distinctive -wing-pattern is 

 generally well marked, and consists of a postmedian and subterminal curved series of 

 small pale spots running almost parallel to the termen of both fore and hind wings : it is 

 best displayed on the underside, and the postmedian series on the fore wing is usually 

 the most sharply defined. In kali, de Nicev., the most aberrant species known to us, 

 the essential pattern is traceable, although the pale spots are purple instead of whitish, 

 and the sex-mark of the male is of the same kind as that found in inachus. 



We separate the species known to us as follows : — ■ 



1 (22). Hind wing below without purple markings. 



2 (9). Sex-mark on the fore wing above in the male a seam passing 



obliquely outwards from the middle of vein 1 a to the base of 

 vein 3. 



3 (8) . Fore wing below with two rows of pale spots — one postmedian, the 



other subterminal. 



4 (7). Hind wing below : space between the postmedian and subterminal 



pale macular bands darkened and divided into a series of spots 

 by the pale veins. 



5 (6). Hind wing below with the subterminal row of dark spots greenish 



brown; markings in cell 7 scarcely developed stigmata, Moore. 



6 (5). Hind wing below with the subterminal row of dark spots velvety 



greenish-black ; markings in cell 7 strongly developed. Fore 

 wing longer in proportion to its width, its termen more distinctly 

 curved chinensis, n. sp. 



7 (4). Hind wing below uniform pale greenish grey, the veins not 



evidently paler than the disc, the space between the postmedian
