122 Lloyd's natural history. 



patch is sprinkled with yellow, and there is a distinct row of 

 small white marks along the median nervure. The hind-wings 

 are ashy-grey, becoming darker towards the hind margin. The 

 fringes of the fore-wings are ferruginous, and those of the 

 hind-wings ashy-grey. 



The larva feeds upon willows and poplars, about which the 

 moth may frequently be seen flying. The former is slender, 

 grass-green, with scattered minute hairs. The incisions are 

 yellow, and there is a white or yellowish lateral line and red 

 stigmata. 



The pupa is black and very tapering, and is attached to the 

 cocoon by its terminal bristle. The cocoon is usually inter- 

 woven with leaves. 



The moth appears in June or July from hybernated imagos 

 or pup^e, and again plentifully in October. It is common 

 from autumn to spring, concealed in weedy banks, under 

 bridges, between the chinks of palings or thatch, and in 

 out-houses. 



III.— NOCTU^ INTRUST. 

 The Intrusts are a small group, including three families, 



all represented in Britain. They are thus defined by 



Guenee : — 



A. — Larvce with the penultimate segment more or less promi- 

 nent, green, with distinct lines, or else with dull 

 uniform colours, and not looping when they walk. In 

 the moth the abdomen is flattened above in both sexes, 

 and the wings are thick and lustrous ... AmphipyridcB. 



B.— Larvre fusiform, of varied colours, and somewhat looping. 

 Moths with the abdomen often inflated in the females, 

 and with the hind-wings well developed, but never brightly 

 coloured, or coloured like the fore-wings. ToxocatnpidiB. 



C. — Larvae stout, cylindrical, resembling those of Orthosiidce in
