284 LEPIDOPTERA. 



oblique, a little rounded off at the anal angle ; dorsal margin 

 nearly straight ; colour pale grey-brown or grey-drab, 

 minutely dusted with darker ; basal line restricted to two 

 short dull brown streaks ; first line rather oblique, obscure, 

 slender, dull pale brown ; second line not very oblique, in- 

 distinct, slender, brown, slightly dotted on some of the 

 nervures, followed by a parallel line of more distinct black 

 dots, and outside these by a pale line; subterminal line 

 irregular, very slender, obscure, forming a pale division 

 through a faintly darker clouding of the hind marginal 

 region ; orbicular and reniform stigmata both large and 

 somewhat rounded, smoky-brown edged with yellowish- 

 white ; below is a very faint, partial, smoky-brown central 

 shade ; touching the costal margin are two or three small 

 round black dots ; extreme hind margin still more minutely 

 dotted with black, outside which, along the base of the cilia, 

 is a slender yellow line ; cilia grey-brown. Hind wings of 

 moderate breadth ; hind margin rather sinuous, clear glossy 

 white, having a pale brown line, dotted with black, along the 

 hind margin ; cilia white. Female extremely similar, but 

 with the nervures of the hind wings pale brown, and the 

 abdomen rather stouter. 



Underside of the fore wings dusky yellowish-white along 

 the costa, shading off to pure white along the hind margin ; 

 nervures white. Hind wings white, the costal area broadly 

 dusted with brown ; hind margin dotted with black. Body 

 and leg-tufts yellowish-brown, legs pale brown. 



Hardly variable here. Continental examples are usually 

 of a rather more ashy colour. A specimen taken by Mr. 

 F. C. Woodforde in Devon is very decidedly dark. 



On the wing here in August and September, but in the 

 South of Europe it is found in June and until October, 

 doubtless in two generations. 



Larva plump, cylindrical ; head round, the lobes dark 

 brown, but the face paler ; dorsal region between the sub-
