In the month of May, 1860, 1 received from my late friend, 

 Dr. Wttewaall, some full-grown savvfly larvae, which he had

 complete drawings of my first brood, I requested my relative, 

 Mr, R. P. van Vollenhoven, residing at Renkum, to send me 

 some similar larvae in case he should be able to find any, 

 with which request he obligingly complied : this was in the

 history of the development of this species, with the exception 

 of a description of the egg. No doubt the egg is deposited in 

 the epidermis of a leaf, or the petiole, very early in the 

 spring. 



On the 8th of May I received seven larvae from Renkum : 

 they were not of the same age, but none had yet undergone
