18 COLIAS HYALE. 



the 22nd one had moulted for the third time ; it was 

 then of a lighter green, but with other details much 

 as before; the pale yellowish-white spiracular stripe 

 was softened above into the green ground colour, but 

 below it contrasted abruptly with the colour of the 

 ventral surface ; the head and all the surface of the 

 body were thickly set with short, pointed, black 

 bristly hairs. 



Of the others one moulted a third time on the 23rd, 

 and another on the 26th. The most forward measured 

 by the 27th four lines and was thick in proportion, the 

 spiracular line very pale whitish-yellow, the spiracles 

 being outlined with black and situated on its lower 

 edge ; other details as before. 



All began to hibernate towards the end of Sep- 

 tember, but after a few weeks' quiet they one by one 

 died off. 



Of four other larvse which had hatched much later 

 from a second batch of eggs received from Herr Hein- 

 rich Disque, which had been kept openly on a potted 

 plant of Dutch clover, I lost two after their second 

 moult by their wandering away from the plant ; the two 

 remaining larvas were then placed under gauze, and 

 they in due course moulted a third time and fed away 

 in October, but first one and then the other died 

 towards the end of that month. 



It seems thus impossible to rear this larva in autumn, 

 the only chance would be to obtain eggs of an earlier 

 brood if possible. (W. B., Note-Book IV, 163.) 



On the 13th of August, 1868, Mr. A. H. Jones most 

 kindly sent me more than twenty eggs which he had 

 obtained from a captured female, and although I failed 

 with the larvas, yet I think my experience may be of 

 benefit to anyone who may have the same chance 

 another time. 



The larvae were hatched August 17th to 20th, first 

 ate their egg-shells and then settled on Medicago lujpu- 

 lina, in preference to Lotus comiculatus, Trifolium 

 repens and prat ens e, with all of which I supplied them.
