This is a generally distributed species : it is plentiful in the London 

 district, also in the Isle of Wight, and has been received from Wales 

 and Scotland ; it is found also in France, Germany, Sweden, and 

 Denmark. It is sometimes infested by a Stylops. 



Variety /3, of which I have only seen a single specimen, may prove 

 to be a distinct species ; it was taken in the Lake- district, and is 

 in the collection of Mr. Benjamin Cooke, of Bowdon, Altrincham.
