t8o LEPIDOPTERA. 



through the corselet, clear and distinct ; at each division of 

 the segments on this line is a large conspicuous smoky mark; 

 subdorsal lines waved and less conspicuous, also ochreous ; 

 spiracles large and distinct, black, with pale centre and 

 edging ; below the spiracles and throughout the ventral area 

 the ground colour is also ochreous, thickly freckled, and in 

 front strongly suffused with purple ; but, being without the 

 admixture of smoke colour, paler than the dorsal area. 



When very young, rich dark green, dusted with yellowish- 

 brown, or else entirely of the latter colour ; head pale brown; 

 dorsal line bluish, shading to white, and edged with smoky- 

 green ; subdorsal line whitish, waved, less distinct, followed 

 by a similar but straighter line above the spiracles ; spira- 

 cular stripe broad, yellowish -white, intersected throughout by 

 a narrow green line. 



Early in the winter, when about to hybernate, reddish- 

 brown with smoky markings ; head yellowish-brown with 

 dark mandibles ; dorsal line yellowish-white edged with 

 smoke-colour and with a similar spot at the segmental 

 divisions ; subdorsal lines similar, more obscure ; spiracular 

 stripe broad, pink ; spiracles oblong, black, those on the 

 twelfth segment enclosing a pale spot ; undersurface, legs 

 and prolegs brownish-pink. (Adapted from a full description 

 by Mr. G. T. Porritt.) 



August to May or the beginning of June on Dadylis 

 glomerata and other grasses, more especially those growing 

 in woods, feeding in the evening and at night; hiding by 

 day at the bases of the grass stems. 



Pupa apparently undescribed. 



The moth does not seem to be noticed anywhere in the 

 daytime, but flies at dusk and is usually captured at sugar. 

 It is local and mainly confined to woods and well-wooded 

 parks, and very uncertain in its appearance. In some 

 seasons abundant in the New Forest, Hants, which seems to 

 be its principal locality with us ; but found also in Epping
