 inch (18-23 nun.). Rather robust ; fore wings long, very 

 narrow at the base, brownish-grey ; Srst line erect, broadly 

 black, deeply indented ; hind wings white. 



Antenna3 of the male simple, the basal joint thickened 

 and rather tufted, brown faintly barred with grey ; palpi 

 small, slender, curved up and closel}' appressed, pale chocolate ; 

 head light brown ; thorax rather robust, pale brown dusted 

 with grey ; abdomen very pale brown. Fore wings long and 

 narrow, very narrow at the base; costa arched beyond the 

 middle ; apex and hind margin rounded ; colour pale 

 brownish-grey, dusted with darker grey ; first line placed 

 far from the base, erect, deeply and repeatedly indented,, 

 black or grey-black and rather broad, but edged inwardly 

 by a yellow-grey line, and followed by a broad central grey 

 band, which extends to the second line ; the latter verj^ 

 obscure, undulating, grey with a paler outer edging ; discal 

 spot a pale brown dot ; hind margin dotted with black ; 

 cilia yellow-brown. Hind wings rather ample, long and 

 somewhat pointed, flatly rounded behind ; shining smoky-

 hind wings silk}^-white. Body and legs yellow-brown. 



Slightly variable in the depth of colour, and of markings, 

 from greater tendency towards brown, or slate-grey. In the 

 collection of the late Mr. H. Doubleday in Bethnal Green 

 Museum are specimens almost grey-black, and Mr. Sydney 

 Webb has others similar in the collection of the late 

 Mr. Bond.
