recorded as British, one from Lincolnshire, and one from near Windsor 
(the latter is in the collection of the late Mr. W. Garneys, and the 
former in the British Museum collection); the species, however, is 
evidently not indigenous ; it appears to be chiefly found on the Continent 
near mountain streams.
