170 LEPIDOPTERA. 



toward tlie anal angle, where it is less distinct ; beyond is a 

 long flat costal spot running into the apex ; cilia yellow- 

 brown. Hind wings white, with white cilia. Female larger; 

 fore wings longer but less broad, not folded ; ground colour 

 more tawny, with the markings most distinct upon the costa. 

 Hind wings and cilia white. 



Underside of the fore wings dull smoky brown with pale 

 yellow dashes on the costa. Hind wings smoky white. 



Variable in size, especially so in the male, specimens of 

 the second generation being often very small. The male is 

 also liable occasionally to the suffusion of umbreous over its 

 fore wings, and the female, more rarely, to a suffusion or 

 clouding of reddish-brown or tawny. Another form, which 

 seems to be confined to salt marshes, is almost or quite 

 devoid of markings, and was at one time supposed to be 

 distinct, the name given it being latiorana. This form seems 

 only to have been found in the salt marshes of the Eastern 

 counties. 



On the wing at the end of June and in July and the 

 beginning of August, also a second generation in September 

 and October. 



Larva not very active, nearly cylindi-ical, but tapering a 

 little at each end ; dorsal region dark smoky olive-green, 

 but below the spiracles gi'eenish-white ; spots whitish, 

 distinct, furnished with short hairs ; head and dorsal plate 

 black ; anal plate greenish-grey. 



May and June, and a second generation in August ; in the 

 tops of meadow-sweet ((§ji/UY' v.bnaricC),Einlohvnin hirsutvm, 

 Comctrum palustre, and many other herbaceous plants in fens 

 and marshes ; on sea-lavender, sea-wormwood and other sea- 

 side plants ; and probably on almost all the herbaceous 

 plants to be found in wet places. Wilkinson says " on 

 reeds and grasses " ; and Sorhagen specifies even Iris 

 pscudacorus, ScirptLs palustris, and Xasturtium 2Mhistre. 



Pupa dull black, in the larval habitation, in a loose white
