IS'ot common, but widely distributed. The record, Armagh ('89 

 J. 5), is to be deleted. In Great Britain this species has been found 

 rarely in the south, and as far north as the Moray district. IS'o doubt 

 it is overlooked in many localities, owing to its resemblance to dark 

 varieties of J3., palustris, L. Ganglbauer records it from France and 

 Belgium.
