land, and Cumberland. In Wales it has been found commonly 

 in Carmai'thensliire, and more rarely so far west as Saunders- 

 foot and Cauastou, in L^embrokesliire ; it must therefore in all 

 probability occur in woods throughout the Principality. In 

 Scotland very widely distributed; found in Roxburghshire, 

 Ayrshire, and elsewhere in the West, also in the districts of 

 the Tweed, Forth, Tay— Kincardineshire, and Aberdeenshire 

 — in West Ross, and even abundantly in Morayshire. In 

 Ireland apparently in most of the wooded districts ; common 

 near Dublin, and recorded from Kerry to Londonderry. 

 Abroad it is generally distributed in the Central and Southern 

 portions of the Continent of Europe, and is found in Southern 

 Sweden, and in Asia Minor.
