succession of, deep black streaks from the base to the anal 

 angle ; hind wings whitish, 



Antennse of the male simple, very slightly ciliated, greyish- 

 brown ; palpi grey, black at the sides ; head and thorax grey, 

 shoulder lappets uplifted ; at the back of the thorax is a 

 small tufted crest, flattened in the middle ; abdomen rather 

 shining, whitish-grey ; basal segment with a broad, spreading, 

 whitish crest, dusted with black or grey ; lateral and anal 

 tufts whitish. Fore wings narrow, the costa slightly rounded ; 

 apex bluntly angulated ; hind margin at first but slightly 

 curved, more fully so toward the anal angle and dorsal 

 margin, which last is rather straight, but curves in, so as to 

 render the base narrow. Ground colour pale grey softlj'- 

 shaded with very faint yellowish ; at the base of the dorsal 

 margin is an elongated yellow or orange-yellow patch, and 

 bordering it, from the base of the wing, a conspicuous black 

 longitudinal streak reaching the first line and there branching, 

 but continued in the same direction by two more successive 

 black streaks along the dorsal region, the third branched and 

 running into the anal angle ; between these and the dorsal 

 margin the space is clouded and streaked with black. First line 

 black, slender, much indented; second line blackish, very indis- 

 tinct, but edged with white, indentedand very deeply hollowed 

 above the anal angle, then bending strongly back makes a 

 wide sweep nearer to the hind margin, but curving in, hardly 

 reaches the costa ; lying in the deep hollow which it forms 

 is a long white crescent which borders a black cloud at the 

 base of the third longitudinal black streak ; orbicular stigma 

 whitish, imperfectly edged with black ; reniform stigma large, 

 tinged with yellow, edged internally with a black line, 

 externally with a faint grey line ; hind margin spotted with 

 black ; cilia greyish-white, dusted with black. Hind wings 

 pale grey or whitish, with a slightly elbowed slender grey 

 transverse line beyond the middle ; hind margin dotted with 

 blackish ; cilia grey. Female with the hind wings a little 

 greyer, otherwise similar.
