258 LEPIDOPTERA. 



brovvu, tufted, apical joint small, pale, and surrounded by a 

 few long scales ; head grey, mixed with black ; thorax grey ; 

 collar and shoulder-lappets raised, the latter edged outwardly 

 with black, an obscure crest at the back tipped with dark- 

 grey ; from below it long fascicles of yellow hair-scales con- 

 verge over the base of the abdomen ; the latter is yellowish- 

 grey, and has upon its basal segment a broad oblique tuft or 

 crest, not very visible from the abundance of long coarse 

 yellowish hair-scales which cover this and the following seg- 

 ments, and rise on the dorsal ridge, into additional, faintly 

 darker, tufts ; lateral tufcs small, yellowish-white, anal tuft 

 similar, but longer and rather divided. Fore wings with the 

 costa very straight ; apex blunt ; hind margin oblique but 

 very little curved till below the middle, whence the curve 

 sweeps round the anal angle ; dorsal margin rather straight ; 

 colour greyish-white, much clouded and marbled with dark- 

 grey ; a black doubly-branched streak from the middle of 

 the base crosses the first line, which is black, indented, not 

 well-defined, but duplicated from the costa to the black 

 streak, thence scalloped to the dorsal margin; second line 

 far beyond the middle of the wing, black, deeply indented 

 and scalloped, but clouded, and sometimes not very distinct ; 

 orbicular stigma conspicuous, white, ringed with black, and 

 placed in a large squared whitish space ; reniform stigma 

 rather long and narrow, accurately kidney-shaped, edged at 

 the back by a black line which arises on the costa, otherwise 

 irregularly margined, and sometimes divided, with black ; 

 inside the second line is a slender parallel edging of white, 

 outside it a broad transverse ill-defined cloudy-grey stripe, 

 beyond which the sub-marginal region is paler grey dappled 

 with whitish ; hind margin spotted with black, the black 

 extending in dashes through the greyish cilia. Hind wings 

 whitish or pale brownish-grey, with the nervures rather 

 browner ; beyond the middle is a faintly whitish transverse 

 stripe ; hind margin more tinged with brown, and with a 

 cloudy brown spot at the anal angle ; cilia whitish. Female
