BRITISH APHIDES. 
This insect is not Aphis artemisim of Fonscolombe 
which Kaltenhach identifies with his Aphis tanaceticola. 
He describes it as green and not unlike S. millefolii. 
Several Aphides seem . to feed on different species of 
Artemisia, and their synonyms are much involved in 
confusion.
