LIPARIDjE. 319 



with greenish ; hairs green or yellow ; dense round obtuse 

 brushes yellow ; long anal tuft pink ; dorsal spaces between 

 the tufts broadly deep black ; and a row of black spots on the 

 sides of the ninth and following segments ; legs and pro-legs 

 green or yellow, like the body. In other cases larvte are pale 

 brown, pale reddish brown, or umbrous, with the head of a 

 similar brown, the dorsal tufts light reddish, greyish, or smoky 

 black ; the long anal tuft pink, brown or black ; scattered 

 hairs generally similar to the body ; and the black subdorsal 

 spots on the hinder segments elongated, connected, and some- 

 times formed into double lines. 



July to September, on hop, hazel, lime, birch, oak, plum, 

 pear, and other trees and plants ; feeding quite conspicuously 

 on the leaves and apparently not resorting at all to the trunk 

 or limbs for concealment. It is extremely common in hop- 

 gardens, where from its curious anal tuft of hairs, like a 

 raised tail, the larva receives the common name of the " Hop- 

 dog." 



Pupa rounded, with rather projecting wing-cases, stout 

 abdomen, and rather sharp anal spike; chestnut-brown, or 

 darker brown, with the edges of the wing-cases and two 

 bands on the abdominal segments paler. In a large ovate 

 loose silken cocoon among dead leaves or rubbish close to the 

 ground ; passing the winter in this state. 



The moth sits in the day-time upon low plants, shrubs, 

 ferns, or bushes, or upon hedge banks ; always with its long 

 densely-tufted fore legs stretched out in front, and bears a 

 most extraordinary resemblance to an entangled downy grey 

 feather, or a mass of the cottony seeds of the large sallow. 

 It flies freely at night, when the males may be assembled by 

 means of a freshly reared female. It also comes readily to 

 light, the male especially being so attracted. It is common 

 in the southern half of England, and sometimes abundant in 

 the larva state ; extending throughout South Wales, and to 

 Staffordshire, Derbyshire, Lincolnshire, Cheshire, Lancashire,
