 also in the Western to Leicestershire, Worcestershire and 

 Herefordshire, and in Warwickshire, Staffordshire, Derbyshire, 

 Cheshire, and Lancashire. Apparently not noticed in Scot- 

 land, and in Ireland only in the counties of Sligo and 

 Londonderry, Abroad it has not the extensive northern

 Livonia, most parts of Central Europe, the South of Spain, 

 Piedmont, Greece, Dalmatia, and Siberia.
