10-A BEITISH APHIDES. 



are other subterranean species not included in this 

 group, it may be useful to give a list of such, most of 

 which are noted in this Monograph. It is probable 

 that some of these, like Pemphigus and Phylloxera, 

 have aerial forms.

ADDENDUM. 



Subsequent to the publication of my first volume, 

 several large Aphides were kindly sent to me from 

 Scotland in the summer of 1878 by Professor Trail, of 

 Aberdeen. They were found feeding on Buhus 

 fruticosa, and they showed all the characters of 

 Siphonophora. 



Unfortunately no winged forms could be secured, 

 which would have permitted a more satisfactory 

 diagnosis. The antenna) and legs of these specimens 

 are remarkably long, the cornicles are more cylindrical 

 than in 8. rubi proper, and the body is hirsute. 



The most striking character is their bright rufous
