A PA TURID^. 107 



iS'o less than niue tigures of the larva aud two of the pupa 

 of this species are given in the late Mr. Buckler's work, as pub- 

 lished by the Kay Society, the attitudes of the larvte being 

 most striking. Indeed, the singularity of the creature has in- 

 spired several writers to supply extremely detailed accounts. 

 Mr. A. B. Farn furnishes in Tin: Enlumoloijid an especially 

 accurate and natural life-history. He covered a sallow bush 

 with a huge bag of leiio, placed therein three captured female 

 l)uttertlies, fed them with the juice of crushed raspberries, and 

 obtained eggs, which were laid on the upper sides of the leaves. 

 'I'he infant larva3 were of a sap-green, with large, round, dark 

 brown heads. Ten days later the lirst moult occurred, aud. 

 with the new skin, the tentacles upon the head suddenly 

 appeared, one third as long as the body and studded with 

 short spines. The tentacles, however, did not grow in the 

 same proportion as the body. On emergence from the egg, 

 each larva took possession of the upper side of the tip of a 

 leaf, where it spun a small silken carpet, leaving it to feed at 

 the side of the leaf, and I'eturuing always to rest. 



Towards the end of October the larvse, havinsr then moulted 

 twice, crawled down from the leaves, and each spun a little 

 silken mat at the fork of a twig with the main branch, aud 

 upon this settled down for hybernation, the tentacles being 

 placed close together and pointing forward, and the whole 

 body having become a dirty brownish-green colour, resembling 

 that of the sallow stem. In this position they remained until 

 April, but all had recommenced feeding by the 1 2th of that 

 month. Early in ilay a third change of skin was accom- 

 plished, and tliey had assumed a lighter green colour, with 

 the dots and oblique lines which give them such a marvellous 

 resemblance to the leaf of sallow upon which they repose. 

 In the middle of June the pupa state was assumed, the pupa 

 being attached to the under side of a leaf which the larva 

 has previously and most carefully bound and firmly attached 

 to the stem, so that it could not fall. Even the edge of the 

 leaf was slightly fixed to the pad of silk so carefully arranged
