It will be seen that there is a great deal 

 of confusion regarding the synonymy of 

 Aphis avenae (Fabr.) Perg., Aphis padi 

 Linn., Macrosiphum avenae (Fabr.) 

 Perg., Macrosiphum granarium (Kirby) 

 Perg. Prof. Oestlund suggests the fol- 

 lowing for the present: 



1758 Aphis padi Linn. 



1906 Macrosiphum avenae 



(Fabr.) Sanb. 

 1904 Macrosiphum cerealis 



(Kalt.) Perg. 

 1904 Macrosiphum granarium 



(Buck.) Perg. 



But he goes on to say that the above 

 has not been thoroughly established and 

 that the present arrangement of Per- 

 gande's should be accepted, which is as 

 follows:
