6 LEPIDOPTERA. 



margin; cilia wliitish, faintly spotted with purplish-grey. 

 Hind wings nearly as long as the fore wings, ample and very 

 fully rounded ; pale grey with a straight, darker grey stripe 

 across the middle, edged outwardly with whitish ; cilia pale 

 grey. Female with the antennee very short and small, slightly 

 toothed, pale brown ; head and thorax brown ; abdomen very 

 stout, whitey-brown, with a dense brown anal tuft. Fore 

 wings slightly narrower than in the male, pale brown with 

 the lines and central band rather deeper brown and edged 

 with whitish clouding ; cilia pale brown spotted with darker. 

 Hind wings pale brown, often whiter toward the base. 

 Otherwise resembling the male, and but little larger. 

 Underside in both sexes pale greyish-brown or dull brown, 

 with a darker brown cloudy stripe through the middle of 

 fore and hind wings ; body whitey-brown. Legs tufted, grey 

 in the male, brown in the female. 



The male is variable in the ground colour of the fore 

 wings from grey to nearly white. In the late Mr. H. 

 Doubleday's collection in Bethnal Green Museum are 

 specimens having the ground colour of a lovely creamy- 

 white ; and Dr. Mason has one of a blackish-grey, with the 

 band still darker. 



On the wing at the end of August and in September. 



Larva cylindrical, elongate, hairy ; head rounded, black ; 

 body sooty-black, sides greyer and paler ; the whole body 

 covered with fulvous hairs, not sufficiently densely so to 

 obscure the markings ; a broad irregular whitish subdorsal 

 stripe, interrupted with orange, and having a black dash 

 beneath it on each segment ; two orange dorsal spots on each 

 segment; a thread-like fulvous line above the spiracles, 

 which are black, edged with white ; beneath them a waved 

 fulvous line. Legs black; prolegs yellowish. The hairs 

 which arise from the pairs of dorsal spots are longer and 

 darker than those on the rest of the body. This larva is 

 beautiful and exceedingly variable. Another form is black
