wider tlian tbe second segment, and flattened in front ; skin 

 somewhat wrinkled ; the whole body, head included, closely 

 set with fine, short, pale bristles ; anal extremity with two 

 short spines pointing backwards. Colour usually pale 

 ochreous, freckled closely on the back with reddish brown ; 

 the head freckled rather more darkly than the body, and the 

 lobes outlined with a dark line ; dorsal stripe dusky, widening 

 ou the middle segments ; sub-dorsal line a little paler than 

 the ground colour, edged, especially above, with some dark 

 freckles; spiracular stripe pinkish-white, edged above with 

 brown freckles and followed below by a yellowish stripe; 

 under surface similar to the back ; spiracles black, very 

 small ; anal spikes pale drab. Some examples are rather 

 darker than this, and some are paler, with a greenish grey 

 tinge. The very young larva has the head large and globu- 

 lar, and the usual dots large, each with a stiff hair ; ground 

 colour whitish grey, with rusty yellow dorsal and sub-dorsal 

 lines ; along the spiracles are two fine lines connected on 

 each segment, and so looking like a row of rather square 

 markings ; head yellowish, dots brown. After the first 

 moult in the autumn it becomes green, with a brownish head. 

 In the early spring the green has become very vivid and full ; 

 the head greenish with a brownish tinge ; the dorsal line 

 dark green ; sub-dorsal line yellowish green ; and spiracular 

 line whitish green. In April the general colour has become 

 greenish grey, and the spiracular line whitish ; and this 

 gi-adually changes as it becomes full fed, in June, to the 

 appearance as already described. (Hellins.) 



On Poa annua, Triticum rcpcns, Dadylis fflomerata, and 

 other common grasses, particularly those growing ou hedge- 

 banks, from September to June, hardly hybernating, but 

 feeding and growing very slowly through the winter. 



Pupa short and thick, its breadth at the shoulders of the 

 wing cases nearly half its length. Much squared in front, 

 but, viewed from below, the corners are angulated, almost like
