Aphis loniceræ Monell. Riley & Monell, Notes on the Aphididæ, U. S. Geol. and Geogr. Survey, Vol. v., Jan., 1879, p. 6.This species is the one mentioned by Prof. Thomas in the eighth Ill. Ent. Rept. p. 104, under the name of Chaitophorus lonicerœ Mon'l Mss.Phorodon mahalek Fonsc. This European species has been very abundant at the Missouri Botanical Gardens, St. Louis. I believe that it has not before been definitely reported as occurring in the United States.
