MAINE APHIDS OF THE^ ROSE FAMILY. 269 



Theobald (1913). The Maine material is named also with 

 reference to Colorado specimens received from Mr. Maxson 

 who has worked out the host cycle as a migration between rose 

 and grain. It is readily distinguished from the foregoing rose 

 species by its non-reticulated cornicles and the greater number 

 of sensoria on antennal III of the alate viviparous female. 

 There is nothing particularly distinctive about the wing char- 

 acters. 



Myzus rosarum. 



(Figure 92, D-C. Figure 96, C.) 

 For the identification of this species I am indebted to 

 Professor Gillette for named material from Colorado for 

 comparison. The accompanying figures of antennae, cornicles 

 and wings will probably serve to characterize this aphid. 

 Maine collection 14-14 was taken on the Maine Campus by 

 Mr. Geo. Newman June 11, 1914. 



RUBUS. 



Aphis rubiphiea n. sp. 



(Figure 91, G-H. Figure 96, F.) 

 An aphid about the size of gossypii and resembling it in 

 wing venation and length oi cornicle, I have taken in Maine on 

 wild red raspberry. A good colony was found June 26, 1906, 

 (44-06), inhabiting the stem and ventral leaves. 



The alate female had head shiny black, antenna dusky, eyes 

 black, prothorax with pale membrane and prominent lateral 

 tubercles; thorax shiny, wings with slender dark brown veins; 

 abdomen glabrous pale green, lateral tubercles prominent, cor- 

 nicles nearly concolorous, perhaps a little darker, cauda green 

 and hairy. The sensoria of antennal III are few (4-5) and 

 confined chiefly to the distal two-thirds. 



The apterous female is pale green with slightly pulverulent 

 abdomen. Cauda and cornicles lighter than abdomen with the 

 tips of the latter black.
