A. rumexicolens Patch. 



Jour. Econ. Ent, 10, 417, 1917. 



This species is known only from Connecticut. For description 

 and figures see Patch (1917a). It seems to come nearest the 

 Anur aphis group.

A. saiiceti Kaltenbach. (Fig. 28, 13.) 



Mon. der Pflanz., 103, 1843. 



This is an aphid inhabiting both Salix and Umbelliferae like 

 Siphocoryne capreae and, except for the straight cornicles of 

 saiiceti, its characters would connect it with Siphocoryne rather 

 than Aphis. It has been collected in Maine on Salix, Heracleum, 

 parsnip and fennel. For description and figures see Patch 

 (1916b). See also following species on parsnip. 



New Haven, 13 July, 1909 (A. I. B.). 

 A. salicicola Thomas. 



111. St. Lab. Nat. Hist, Bull. 2, 1877. 



This willow aphid is figured by Patch (1913a). A. saiiceti is 

 involved in synonymic difficulties in both Europe and America in 

 which salicicola is also mixed. They are two good species but just 

 what they should be called is not perhaps, yet certain.
