288 LEPIDOPTERA. 



longer and slightly more pointed, light unibreoiis or pale 

 wainscot-brown ; bind wings broader, the sinuous stripe 

 more distinct, and often another, more slender, lies nearer 

 the base. 



Underside of the fore wings brownish-white, more tinged 

 with brown toward the apex, the discal spot and second line 

 faintly indicated ; hind wings whiter in the male, similar in 

 the female, showing in a faint degree the markings of the 

 upper side. Body and legs pale brown. 



Variable in the depth of colour of the fore wings, in the 

 male from pale brown to white, in the female from jjale to 

 deep umbreous ; also in the distinctness of the markings of 

 both fore and hind wings. 



On the wing from the end of May till the beginning of 

 September, probably in a single generation. 



Larva cylindrical though tapering a little on the four 

 anterior segments, and also on the two hinder ; the legs and 

 anal prolegs well developed, the ventral prolegs moderately 

 so; skin soft and smooth, and furnished with eight rows of 

 flexible branchiaB composed of tufts of six, or less, slender 

 fleshy filaments of unequal length, tapering to rather fine 

 points, all radiating from a short thick basal stem, and occu- 

 pying the positions of the usual warts or raised dots. To 

 the unassisted eye they resemble the spines of some butterfly 

 larva. Head pale brown, the lobes delicately outlined with 

 dark brown ; the mouth and ocelli blackish-brown ; the 

 brauchias dirty whitish-grey; body semitranslucent, pale 

 olivc-ochreous, or whitish-ochreous, generally tinged with 

 olive, and marked with a few small purplish freckles ; dorsal 

 stripe broad, dark grey, or brownish, or greenish-grey; 

 spiracles small, black, each situated on the flat centre of a 

 swellina' eminence ; a small wart-like tubercle, near the base 

 of each ventral proleg, bears a single hair-like filament.
