at least. Also far from uncommon in the western half of 

 Scotland, even to Sutherlandshire, much scarcer in the 

 eastern half, and in Aberdeenshire and the Forth district 

 very rare. Local in Ireland but widely distributed, occurring 

 in Wicklow commonly, also in Galway, Tyrone, Armagh, at 

 Enniskillen, and commonly at Londonderry. 



Abroad it is common in Central Europe and also found in
