Abstract

A key is given for seven species of Aphis L. that occur on Cornus species in North America: caliginosa Hottes and Frison, corniella (Hille Ris Lambers), cornifoliae Fitch, helianthi Monell, maculatae Oestlund, neogillettei Palmer, and a new species that is described, nigratibialis Robinson. Host transfer attempts with helianthi and corniella are discussed.
