r^pot is placed beyond the middle : hind margin and cilia 

 nearly white. Hind wings glossy, pale smokj-brown, faintly 

 banded with a darker tint of the same. BodjT yellow-brown ; 

 legs similar, but the tarsi black-brown barred with green. 



The ground colour commences to fade so rapidly after 

 emergence, especially if the weather be damp, tliat it is 

 difficult to say whetlier it naturally varies at all. It is seldom 

 captured in perfect colour, though very often found faded 

 quite to dull dirty yellow. But there is much variation in 

 the extent and degree of the dark markings ; these in some 

 specimens are diffused almost all over the fore wings, in 

 others are concentrated into a dark central band, or set 

 apart into two, three, or four stri]ies, or occasionally almost 

 obliterated. Often the basal space to the first line is of the 

 ground colour, almost immaculate, ecpially often it is fully 

 clouded with fine bine-black lines, and the same may be said 

 of the hind marginal area. A specimen in the collection of 

 Mr. P. W. Abbott, taken at Sutton Park, near Birmingham, 

 has the whole of the dai'k markings obliterated except a few 

 minute dots indicating the outer transverse lines. Sjiecimens 

 of the second generation are usually smaller than those of 

 the first. 



On the wing in May and the early ])art of -iune, and, as a 

 second generation, in August and the beginning of September; 

 but this last emergence is partial and seems to be restricted 

 to southern or sheltered districts. 



Larva thick and stumpy in appearance, the head glossy, 

 partially fitting into the second segment, which is smaller 

 than the third and fourth, they being tumid above and at 

 the sides ; last two segments also tapering a little to the end, 

 where are two minute anal points; all the segments plump, 

 yet with two or three transverse wrinkles at each end ; the 

 skin velvety ; ground colour always some tint of pale green ; 

 in one variety the head and thoracic segments are much 

 suff'used with ])ink, and on the fourth segment a lateral
