Chrysopa dorsaUs was first discovered in England by the late 

 Mr. Alfred Beaumont, at Oxshott, in Surrey, on July 7tli, 1900. It 

 was subsequently described by the late Mr. McLachlan in the Ent. 

 Mo. Mag., vol. xxxvii, p. 39. Since then I am not aware of its having 

 occurred in any other British locality, with the exception of the one in 

 Norfolk, from which the specimens I received were sent. 



Before bringing this paper to a close, I should like to place on 

 record my indebtedness to Mr. Atmore for his kindness in enabling 

 me to breed this handsome and rare British species. I had long 

 cherished a wish to work out its life-history, but it was a desire I never 

 expected to see realised, so iny pleasure was all the greater ; and more 

 particularly, as the insects were sent in response to a casually expressed 

 wish, contained in some correspondence which I had had with Mr. 

 Atmore a year previously. I only wish I had been better qualified to 

 reap to the full the advantage of an experience which falls to the lot 

 of few, the delight of watching and recording for the first time the 

 metamorphoses of a hitherto unobserved British insect. I trust 

 Mr. Atmore may be able to supplement tliese few notes, at some 

 future date, with further observations taken in the field, in his unique 

 position of being able to study the insects in their natural habitat and 

 surroundings.

FURTHER NOTES ON CHRY80PA DORSALIS, Bukm. 

 BY E. A. ATMORE, F.E.S. 



Miss Alderson has very Idndly forwarded to me her manuscript 

 " Notes on C. dorsalis " prior to their publication in this Magazine, 

 th\is giving me an opportunity of supplementing them with observa- 

 tions of my own. And first of all, I heartily congratulate Miss 

 Alderson upon the success she has achieved in rearing this interesting 

 insect from the egg. Moreover, I willingly accede to her request that 

 I should put on record a little of my experience of this Chrysopid. 

 It is (j[uite true that it has been my good fortune to be able to watch
