l8 LEPIDOPTERA. 



On the wiug in July and August. 



Lakva ratliei- stout ; head of the same width as the second, 

 but narrower than the third segment, lobes rounded, but 

 the face flat and square, there is a slight notch on the crown, 

 pinkish-grey freckled with black; the body has the sides 

 swollen into a puckered spiraciilar ridge, which gives it a 

 rather flattened appearance, both above and below ; the 

 middle segments are the widest and it tapers a little at each 

 extremity; segments overlapping so that the divisions are 

 distinct; skin tough, pinkish-grey tinged with pale slate- 

 blue ; dorsal line slate-blue ; subdorsal lines pale ochreous- 

 yellow, narrowly edged above and below with pale brown ; 

 the swollen ridge along the spiracles pinkish ; s])iracles and 

 dorsal dots black ; ventral surface pale slate-grey ; down its 

 middle is a pale ochreous stripe, throughout which extends 

 a narrow pink line, and between this ventral stripe and the 

 spiracular region is another pale ochreous stripe, edged on 

 each side with black, the outer line being broader and more 

 distinct than the inner; legs and prolegs pinkish-grey. 

 (G. T. Porritt.) 



September to June, on vetches, clover, and grasses. 

 Curtis says on Bromus arvensis. Hofmann gives, as food, 

 Lathyrus pratcnsis, Trifolium rcpcns, Lotus corniadatiis, and 

 Viola hirsuta; feeding at night. It is stated by Mr. J. Arkle, 

 in the Entoiiiohgist, that it may be beaten out of nettles, also 

 that it spins a whitish silken cocoon among their leaves ; 

 but he does not say that the larva actually feeds on nettle. 



Pupa apparently undescribed. 



The moth frequents grassy places in and near woods, hills, 

 banks, and fields, wherever rough herbage is allowed to 

 grow, and often is exceedingly plentiful about road-sides and 

 hedge-banks. Here it sits during the da\' among the tall 

 grasses and coarse herbage, head down, but always on the 

 alert, ready at the approach of any intruder to spring up
