COCOON-MAKING. 207 



have touched the light tufts before the final 

 pulling together and closing in of the top, whilst 

 others could hardly manage to finish their cover- 

 ing, and seemed to search about most anxiously 

 all over their bodies for a forgotten tufc of hair. 

 When all was finished the cocoon looked like a 

 little long pyramid of black and grey plush, 

 lighter at the top. They took about three or 

 four hours making, and those where the cater- 

 pillar had recklessly wasted his hair were always 

 uneven. 



The caterpillar of Euchromia lethe, a yellow 

 and black Burnet, is covered with yellowish- 

 white hair, and makes a similar cocoon. 



One grey mottled caterpillar encased itself in 

 a grey network along a branch, looking exactly 

 like a rough widening of the stick. 



I found two broods of little greenish cater- 

 pillars with black spots, about three-quarters of 

 an inch long, whose custom was to enclose a 

 cluster of leaves in a fine silky loose web, and 

 feed on the leaves so enclosed, migrating to 

 another branch when the first was finished.
