crest at the back ; fascicles sTiort, closely curved, suow- 

 white; abdomen pale yellowish-brown ; basal portion whiter ; 

 lateral tufts small ; anal tuft long, yellowish. Fore wings 

 very narrow at the base ; costa straight ; apex rather sharply 

 angulated ; hind margin gently rounded, more so below the 

 middle ; dorsal margin straight ; coloui" very pale wainscot- 

 brown or yellow-brown, or even whitish-brown ; subcostal 

 region often paler, or dusted with grey or white ; basal line 

 scarcely visible, indicated by fragments of curved brown 

 lines near the costa ; first line double, dark brown or black, 

 fornaed into three rough crescents, and placed rather obliquely 

 outward to the dorsal margin ; second line a curved series of 

 small black crescents with long points, the enclosed spaces 

 often showing as whitish spots ; beyond is a transverse band 

 of roughly wedge-shaped black-brown streaks edging tbe 

 subterminal line, which is very indistinct, pale brown ;

 with black ; extreme hind margin edged with slender blackish 

 crescents ; cilia light brown. Hind wings rather small, 

 rounded, pure white, or with the faintest possible tinge of 

 brownish on the nervures and hind margin ; cilia pure 

 white. Female similar, with simple antennse, stouter body, 

 and the nervures of the hind wings more distinctly pale 

 brown, also in some instances a clouding of pale grey-brown

 even strongly marked, showing all the markings distinctly ;
