E(ESELIA, 53 



of skius present. Full-grown larva snow-white, covered with a 

 down-like detachable substance with slight creamy tinge below ; 

 the hairs white, except five or six long black hairs on thoracic 

 somites ; liead buff marked with brown strise ; a dorsal black mark 

 on 1st somite, partly hidden by the tuft which after the last moult 

 bears five head-skins. The larva progresses with a jerky motion. 

 It forms a boat-shaped cocoon by biting off pieces of rotten wood 

 and bark and interlacing them with the long hairs which are left 

 projecting; before fastening down the flap of cocoon it rubs its 

 head against it for a long time, and with much difficulty detaches 

 the tuft and head-skins and attaches them to the side of cocoon.
