ADDITIONS TO THE LIST OF KENT APHIDID^. 101 



found oviparous females, also of the Woolly Aphis {Eriosoma 

 lanigera, Hausmann), and as far as recent experiments go that I 

 have carried out, there does not appear to be any migration between 

 the elm and the apple in this country, as has been shown to occur 

 in America by Miss Edith Patch. Moreover, I have had one badly 

 attacked apple tree netted for some three years, and no alatfe 

 whatever have appeared. Reproduction without sexuparae in 

 some species may evidently occur for a long time. The list 

 given here does not include any fresh localities for the Aphides 

 of Kent so far recorded {vide 'Entomologist,' January, 1911, 

 pp. 16-21, and November, 1911, and January, 1912), only new 

 species found in the county.
