This insect is very nearly allied to P. tilice and dubius, but it is 

 most likely to be mistaken for the former. Its general darker appear- 

 ance may serve to distinguish it from that insect and from P. duhius 

 by its unicolorous head and black base of the 1st joint of the antenna). 



A few examples have been taken on palings at Bl ackheath, in 

 Bexley Eoad, and round Lewisham, between the end of July and 

 end of August.

This insect may be distinguished from L. concolor^ to which it is 

 closely related, by its larger size and duller appearance {concolor being 

 of a deep, somewhat bluish-green colour, and having a much darker 

 membrane), and its unicolorous cell nerves. \ 



"We have only seen a single example which we can refer mth any 

 certainty to this species. It was taken in Bexley Eoad, Kent, on the 

 5th August, and was probably beaten out of sallow.
