OOLIAS EDUSA. 15 



The hinder segments now continued to heave a little, 

 which brought the old skin of the larva farther and 

 farther behind, until at length, with a slight dexterous 

 twist, it came off the last segment and remained 

 shrivelled up close to the tail of the pupa. Four 

 minutes more had now elapsed, and presently the beak 

 was by degrees developing itself in front of the head, 

 while the keel of the thorax became more and more 

 sharply prominent, and the projections previously 

 noticed at the cheeks took the less prominent and 

 rounded form of eye-covers ; the leg and antenna- 

 cases, which hung down in high relief at their first 

 disclosure, were now sunk back, as it were, to the more 

 level surface of the breast of the pupa ; at the same 

 time the divisions of the upper segments closed up, and 

 the wing-covers swelling out assumed their proper 

 contour. 



These adjustments and the consolidation of the form 

 and skin of the pupa occupied an additional twenty 

 minutes. 



Another larva assumed the pupa form the following 

 day, and by the twenty-seventh eight other larvae had 

 spun themselves up. 



About the 10th of October (1877) Mr. C. G. Barrett 

 captured a female Edusa near Pembroke ; he placed 

 her on clover under gauze in his garden, and on the 

 12th of October she laid some eggs, which I received 

 from him the following day. These eggs hatched on 

 the 27th of October. The young larva made its first 

 meal of the egg-shell it has quitted, leaving only just 

 the lower end of the shell uneaten. (W. B., Note 

 Book III, 187.)
