Extract
A number of species have been described as new from the West since the publication of Mason's revision of the genus Amphorophora (Proc. U. S. Nat. Mus. 67: 1-92, 1925). To make clear the characters and relationships of some of these aphid species, and particularly those which infest berry crops, the present key has been prepared.
