Aphis of the Beecii-tkee. 

 This little-known species of green-fly is very abundant under the leaves of the beech, but it is vers- difficult to see the individual Insects as 

 they cover themselves with a profuse excretion of wool-like filanients. Thev also produce large globules of a sweet liquid. In the small 

 inset photographs above two individuals that have wandered from the crowd are shown. That to the right is a wingless female, with 

 long woolly appendages from the hind-body; on the left is a winged male, .-^bout five and a-half times the actual size.
