136 BKITISH APHIDES. 



Length, of antennse 

 5, cornicles 



Head and thorax pale brown. Abdomen fusiform, 

 pointed behind ; pale green, with brownish stains on 

 each segment. Cornicles minute, green. Body hir- 

 sute. Legs wholly green, and very hairy. Wings 

 simple, narrow; insertions and cubitus green; stigma 

 greyish ; other veins dark green or olive. 



Only a single winged specimen could be secured. 



Found in companies of about fifty, raising blisters 

 under the leaves of PopnJus nigra, Haslemere. When 

 the insects swarmed together they formed black patches 

 on the upper surfaces of the leaves. The larvae are of 

 many shades of green and vary much in their mark- 

 ings, some being entirely devoid of the above-described 

 dark bandings. The companies are often mixed with 

 individuals of Chaitophcrus populi, July. 



Koch's figure of the winged insect is much darker 

 than that I figure, but something may depend on the 

 age of the insect, and the time elapsed after emergence 

 from its pupa.
