64 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 67 



Biology. — I have found this species sparingly on the stems of 

 raspberry, never on the leaves. Pergande says in his notes: "Found 

 on stems of Ruhus, which they sometimes covered for a distance of 

 several inches. Drop readily, if disturbed." It probably remains 

 on Ruhus throughout the year. I have examined specimens taken 

 June 26, 1903, in Virginia (type); July 11, 1903, Minnesota; June 20, 

 1905, District of Columbia; July 10, 1919, West Virginia; June 20, 

 1920, Pennsylvania; September 20, 1921, Maryland; and September 

 13, Massachusetts. 



Distribution . — Massachusetts, Pennsylvania, Maryland, District of 

 Columbia, Virginia, West Virginia, Ohio, Minnesota, and Kansas. 



Host. — Ruhus. 



Ootypes. — Deposited in U. S. National Museum. Cat. No. 26379. 

 Paracotype slides in the National Museum and in the collection of

 Myzoides persicae (Sulzer) Van der Goot, Beit, zur Kennt. der Hollandis- 



chen Blattlause, 1915, p. 170. 



This species is not known to me. It was first taken b}^ Thomas 

 at Carbondale, 111., on May 26, 1878, and described by him in 1880. 



In 1913 Davis redescribed it from specimens in the Illinois collec- 

 tion, which he considered to be the type specimens and gave camera 

 lucida drawings. These appear to be of a valid species of Amphoro- 

 phora. 



Ashmead " discusses a tomato aphis under tliis name, but I am not 

 certain that he had the same species.
