150 r December, 



moulting and continued at intervals ; their propensity was now noticed 

 by Mr. Jeffrey, who reported finding one of his larvae badly bitten, and 

 mine presently being reduced in number to six, I took the precaution 

 henceforth, to keep each separate. 



After this they continued to feed a little, as evidenced by ravages 

 in the food and by small heaps of frass, at intervals ; although they 

 always seemed to me to be sleeping away their time as though it was 

 of no importance whatever, and their growth was most remarkably 

 slow, though singularly enough, Mr. Jeffrey succeeded in bringing one 

 of his brood — but only one — to full-growth by 5th of November, when 

 he very kindly sent it to me to watch, to figure, and note, and on the 

 10th it spun up ; but as no other of his nor any of mine could be in- 

 duced to follow this example, and as the proper time for any further 

 moult had long expired without the occurrence, and cold weather 

 coming, I unwillingly saw they intended to hibernate, and feed up in 

 spring ; and this really proved to be the case, for, with the above- 

 mentioned single exception, none became full-fed much before the end 

 of May, 1882. 



The perfect insects, male and female, eight in number were bred 

 by Mr. Jeffery, and three also by myself, from June 29th to July 11th. 



The egg oiflammealis is a longish-oval is shape, rather large for 

 the size of the insect, the shell, minutely pitted on the surface, is 

 whitish and glistening ; it adheres to the substance whereon it is laid 

 either on its side or standing on end, as well also to each other when 

 laid in little clusters, and I found after six days it was very faintly 

 tinged with greenish and in four more days it hatched. 



The newly-hatched larva is very slender, translucent, and so 

 slightly tinged with flesh-colour as to be almost white, with grey-brown 

 head and narrow plate on the second segment ; on the third day after 

 feeding on hazel the body is tinged internally with crimson, or if fed 

 with the flower and leaves of Lotus major only, the internal vessel is 

 tinted with bright green, and in either case the head and narrow plate 

 are of a deep bright red ; it nibbles away little holes quite through 

 the leaf at some time or other during the first twenty -four hours, from 

 either the upper or under-surface, but is soon after to be found on 

 the under-side where it has spun for itself a little web of such delicate 

 gossamer as to be hardly visible on the hazel leaf, or in the flower and 

 leaflets of the Lotus. 



After the first moult it is still slender, the head and plate are 

 dai'k reddish-brown, the skin of the body less translucent, though 

 Btill tinged with red from the interior, and now, by help of a strong
