ENDOTRICHA FLAMMEALIS. 59 



pensity 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 one separate. 



After this they continued to feed a little, as evi- 

 denced 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 bis brood — but 

 only one — to full growth by the 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 induced 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 the 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. Jeffrey, and three also by 

 myself, from the 29th of June to the 11th of July. 



The egg of E.flammealis is a longish oval in shape, 

 rather large for the size of the insect ; the shell, 

 minutely pitted on the surface, is whitish and glisten- 

 ing: 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 flow T er and leaves of Lotus major only, the
