MAINE APHIDS OF THE ROSE FAMILY.* 



Edith M. Patch. 



It is the purpose of this paper to give descriptive accounts 

 with drawings of those aphids found in Maine upon the mem- 

 bers of the rose family. The most serious of the apple aphids 

 have been treated elsewhere and will receive little more than 

 mention here. Our plum aphids, however, have not been 

 worked up before and as some of these are troublesome each 

 year it seems desirable to have them recorded. Also plants, 

 whether weeds or ornamental varieties, whidh are allied to 

 vegetation of economic importance are suitably included in the 

 same treatment, as certain aphids do not confine themselves 

 to one species of plant but take several closely related species. 



AMEEANCHIER. Juneberry. 



ProciphiIvUS corrugatans Sirrine. Woolly Aphid of Hawthorn 



Leaf. 



(Figure 93, D-E. Figure 95, L.) 



A species which I have been considering the insect described 

 by Mr. Sirrine is common in the vicinity of Orono upon both 

 Crataegus and Amelanchier^ inhabiting the ventral surface of 

 the leaf which it distorts into a rolled curl. Professor Gillette 

 (1909) has figured the antenna of this species and recorded it 

 from various parts of the United States. Mr. J. J. Davis 

 (1911) states that both the Colorado and Maine specimens are 

 alnifolia\e of Williams. Thus unless alnifoliae is a synonym 01 

 corrugatans, the species under consideration should be known
