and hibernate, remaining throughout the winter in the moss at the foot of the trees. 

 In this state, coiled round in a spiral form, they may be frozen quite stiff, yet on 

 the return of spring they regain vitality, and climb the trees in search of their usual 

 provender. The red-brown cocoon is spun sometimes between the needles of the 

 tree, as represented in the illustration, or else beneath some semidetached piece 

 of bark. In the procession moth (Gastropacha processioned} the fore-wings are 

 yellow gray, with a glossy sheen, and dark indistinct oblique transverse bars. The 

 larvre are hairy with a blue-black back, pale sides, and red or gray warts on each

segment. At night the caterpillars march out to feed in a regular orderly proces- 

 sion, as represented in the illlustration. One, the leader, marches at the head, 

 followed by two, three, and so on, forming a wedge-shaped column. They 

 ascend the oak trees and return again in the same manner to their resting place. 

 They also spin their cocoons together as in Fig. 5 of the illustration. The species 

 is common throughout Central and Southern Europe in August and September. As 

 our last representative of the family we take the lackey moth (Clisiocampa neustria), 

 which is common in England and all through Europe and North and Western Asia
