Rev. Huard informs me that the types of the species have 

 been destroyed. Numerous specimens answering in every 

 way the description of the species were reared by the writer at 

 College Park, Maryland, from the rose aphis (Macros/p/iiint 

 roses L.,) and two specimens also from the cherry aphis, 

 (Myzus cerasi Fitch. ) 



An examination of the type of Ephedrus completiis Prov. 

 revealed the fact that it did not belong in the Aphidiinae at all, 

 but belonged in the genus Hormins Nees, and Mr. Viereck, 

 to whom the type was shown, recognized it at once as the 

 species described by Ashniead under the name Hoiinius ery- 

 thr oo aster. Since the Provancher description antedates that 

 of Ashmead the species will have to be known as Honniits 

 completiis Prov. , although that name is distinctly inappropriate. 



The conclusions set forth in this paper have been arrived at 

 only after careful comparison and study of type or homotype 

 material. It is the writer's belief that further examination of 

 large series of reared specimens so as to learn more about the 

 range of variation in the different species will result in the 

 recognizing of a number of other cases of synonymy, and it is 

 planned to continue the study in the hope of ultimately arriving 

 at a better understanding of the group. 



Grateful acknowledgment is hereby extended to Mr. J. C. 

 Crawford and Mr. H. L. Viereck for the opportunity to study 

 the types in the United States National Museum, as well as for 

 other courtesies; to the Rev. V. A. Huard and Prof. R. H. 

 Pettit for the loan of types; and to Mr. Claude C. Morley for 

 his kindness in comparing specimens with the Marshall and 

 Haliday types in the British National Museum.
