SUBFAMILY APHINAE 283 
as in cerei. However, an alate male of the latter species was taken July 20, 
indicating the possibility of sexuales as early as in the former species although 
they have not yet been found in abundance. The species of host plant also 
differs. From K. ribifolii (Davidson) this species differs in length of rostral 
IV+V (longer than .14) and length of cornicle (longer than .27). 
Drawings are hardly necessary because this species differs so little from 
K. cerei.
