EUPITHECIA TOGATA. 49 



they gave no other sign of their presence. How they 

 would act in nature I cannot say, — whether they 

 would ever open an outward passage, and so travel 

 from bud to bud, or whether they would remain quite 

 hidden after their first entrance ; but I am sure each 

 individual eats enough to destroy all the buds on a 

 long young shoot by the time it becomes full-grown. 

 I left my larvae undisturbed for some time, but about 

 the 6th of August I saw one of them come out of its 

 tunnel and walk restlessly about ; I then carefully 

 examined all the other tunnels, but could find only 

 one other larva, and that apparently dead. I now 

 put in a fresh supply of spruce, placing both the 

 living and the dead larvae on it, and when I next 

 looked I found the former busily engaged in finishing 

 up the remains of its defunct relative ; I concluded, 

 therefore, it had also been the cause of the disappear- 

 ance of the others, owing, perhaps, to its being 

 deprived of tender food by the drying up of the juice 

 of the spruce buds. After this it fed away steadily 

 on spruce, and moulted thrice, and on the 19th of 

 August I sent it to my friend the Rev. H. Harpur- 

 Orewe ; from him it was sent to Mr. Buckler, and fed 

 away until the 25th of August, when it began to hide 

 itself in some peaty soil with which it had been sup- 

 plied ; on the 26th it disappeared totally, and by this 

 time is, I hope, in the pupa state. It was supplied with 

 bits of spruce shoots and bark, but it seemed to take 

 naturally to the soil for pupation, so that it is probable 

 that in nature it would eat its way out, and drop or 

 crawl to the ground ; and the pupae should be looked 

 for at the foot of the trees. 



The egg is very broadly ovate, much wider, although 

 but little longer, than that of E. castigata; it is 

 straw-coloured at first, afterwards becoming bright 

 vermilion. 



The young larva when first hatched is something 

 of the colour of the bark of a spruce shoot, being pale 

 olive-brown ; the head, plate on the second segment^
