210 THE entomologist's record. 



species, whilst the marshes on both banks of the Thames, especially 

 towards its mouth, were among his favom-ite hunting grounds. 

 But he did not neglect the Macros, and the careful notes and 

 dates which he kept of the species he bred often proved of the 

 greatest value, and he published a considerable quantity of data 

 at the time of a furious discussion on " The prior emergence of 

 male and female Lepidoptera " in The Entomologist, vol. iii. As 

 an example of the number of species he frequently bred in a 

 season, we find a very long list in 1868 (Id., pp. 12G and 154). 

 Latterly his health has been very unsatisfactory and more than 

 one serious attack of illness has prostrated him, but breeding insects 

 still kept all its old charm for him, and to his kindness many 

 of us owe our lovely specimens of Phorodesma smaragdaria. So 

 recently as April 17th last it was my i)leasure to have a chat witli 

 my old friend, and although I expressed the hope that his health 

 would improve, suffering was evidently written on his features 

 and the disease (cancer) from which he died had left a serious mark 

 on him. To the end his active interest in Entomology was maintained, 

 and he was perfectly an fait with every addition to the British 

 fauna. Even so lately as in the July number of The Entomologists 

 Record an exchange notice appeared offering one of his earliest 

 loves — SeJenia lunaria. He has exceeded the three score years and ten 

 allotted to man, he has led a hai)py and useful if unobtrusive life, 

 opened up for us some of the many bye-ways to Nature's secrets, 

 endeared himself to many friends who will not blot out readily the 

 memory of liiui from their minds. His collection is a very fine one, 

 being especially rich in Tortuices and Tineina and the whole are in 

 the most perfect condition. It is one of those reliable collections 

 composed entirely of British species which represent a labour of love 

 spread over a man's whole life. — J. W. Tui't.

5. — On the limitation of the subject in the present paper. — 

 As I have already stated, the embryonic life of an insect must be held 

 to include all the stages between the fertilization of the ovum and the 

 emergence of the imago. The following notes, however, only deal with 

 that portion of the embryonic development which takes place within 

 the egg, and it must be understood that hereafter I use the term embryo 

 with that limitation. 



6. — On the method of observing the changes that take place 

 in the egg. — This can only be done by the aid of a microscope. In 

 examining eggs with a microscope, very little in the way of apparatus 

 is necessary. My own instrument is a very simple one with no
