ADDITIONS TO THE LIST OF KENT APHIDIDA. 101 - 
found oviparous females, also of the Woolly Aphis (Hriosoma 
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 alate 
whatever have appeared. Reproduction without sexupare 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 ‘Hntomologist,’ January, 1911, 
pp. 16-21, and November, 1911, and January, 1912), only new 
species found in the county.
