shorter of the two) and then the other, and next the 

 tibise and tarsi of the long second pair were liberated, 

 all playing immediately after in unison with the whole 

 body, which now unbending sustained its hold of the 

 twig by one ventral proleg only of the fourth or hind 

 pair, and while the old skin glided backwards by 

 degrees the other ventral prolegs were in turn slowly 

 stepping out as it were of their old stockings. At this 

 time the long front crustacean-like legs began im- 

 patiently to play about and push at the old head-piece 

 as cleverly as arms and hands to weaken the attach- 

 ment and free the mouth parts, and from them the old 

 helmet fell away just as the second pair of ventral 

 prolegs were uncovered. 



Meanwhile the hinder segments of the body had 

 become drawn out straight and narrowly cylindrical 

 though tapering, the caudal filaments drawn close 

 together, forming apparently but one projecting point, 

 which now with the hinder portions of the body became 

 elevated almost perpendicularly, as the fore parts with 

 the head and anterior legs were lowered in contact 

 with the mouth of the bottle, evidently feeling for the 

 leaf, which, as before mentioned, had been previously 

 cut away ; the third pair of ventral prolegs were next 

 uncovered, and then one of the fourth pair, when, as 

 the moment approached for the only supporting leg to 

 let go its tenacious hold of the twig, I instantly held a 

 silk handkerchief round the neck of the bottle just as 

 the leg was removed and the old skin drawn back from 

 it, and then the larva lay sprawling and trembling on 

 the mouth of the bottle as the shrivelling skin drew off 

 from the eleventh segment, and after a few efforts to 

 hold itself on the bottle, slipped off upon the soft sur- 

 rounding material, whereon for two minutes it remained 

 perfectly still, making the first pause from the inces- 

 sant motion which had been so long continued. It 

 now lay at full length with the hinder segments 

 slightly turned aside, all the ventral prolegs sprawling, 

 the anterior legs extended forwards in freedom, motion-
