In listing the above species, I place a question mark (?) 

 before 4 species on account of the variation which Rafiuesqtie 

 gives to antennae and nectaries. Considering the fact that 

 Rafinesque considered the winged specimens as males, and 

 speaks of the males in one species being larger than the females, 

 he must have at times considered immature specimens as 

 females ; such specimens correspond to the above questionable 

 names (descriptions). In one description he mentions the 

 fact that the appendages grow longer as the individuals ma- 

 ture. In yet another description he mentions that the*antenna 

 are longer than the body and the appendages are very short. 

 This species apparently was a Macrosiphum and I have so 

 considered it.
