296 LEPIDOP TERA . 



dark brown transverse line edged outwardly with white ; 

 extreme hind margin bordered by a slender dull black line ; 

 cilia of the ground colour. Female very similar but with 

 the fore pair of legs devoid of the curious tufts of hair- 

 scales, the antenna? quite simple and the body rather thicker. 



Underside of all the wings very pale smoky yellow-brown ; 

 in each is a central black-brown dot followed by two slender 

 brown transverse lines ; under portion of the tarsal fans of 

 the male nearly black ; body and legs otherwise yellowish- 

 brown. 



Usually not variable in any important degree, but the 

 Rev. C. T. Cruttwell has shown me that in Suffolk the fore 

 wings of this species are often of a greyer tinge. 



On the wing in June and July. Individuals of a second 

 generation have been reared in confinement in September 

 and October. The second brood is rare and doubtless only 

 very partial out of doors. 



Larva, when full grown, from six-eighths to seven-eighths 

 of an inch in length, moderately stout and cylindrical, tapering 

 just a little at the last two segments and also in front from 

 the third segment to the head, which is globular, dark 

 brownish-grey ; dorsal plate rather paler and dull ; general 

 colour dull brownish-grey, finely freckled with a darker tint, 

 but in both respects paler below the spiracles ; dorsal line 

 blackish-grey, somewhat interrupted in the middle of each 

 segment; subdorsal lines pale greyish-brown, continuous on 

 the thoracic segments, but indicated only by a short dash at 

 the beginning of each of the others, and below this dash 

 there is, lower down on the side, a short thick blackish 

 streak bifurcated a little at its hinder end ; spiracles black ; 

 raised dots blackish, ringed with paler than the ground 

 colour. The whole skin covered with an exceedingly fine 

 pearly pubescence. (W. Buckler.) 



July or August till April, apparently becoming full-grown 

 before hibernation, though not assuming the pupa-state till
