Note. — Joshua Major, in his "Treatise of the Insects Most 

 Prevalent on Fruit Trees, Etc." (p. 10, 1829) mentions Apple 

 Aphides of various kinds, and evidenth' refers to this species, and 

 not to A. avencE, as has been suggested. 



*Oestlund (.Aphid. Minn. p. 64, 1877) thinks this a variety of mali but his mali 



is certainly avevm. 

 tGillette and Taylor called this pyri after Koch's description, but Boyer's pyri 

 antedates Koch's.
