as it advances northwards, and in most years scarce in 

 Cheshire, Lancashire, Yorkshire and Cumberland, though it 

 has its abundant seasons. Probably the same is the case in 

 Wales, since it was noticed in one season only while I was in 

 Pembrokeshire, but was then fairly common. Very scarce in 

 Scotland, but recorded from Roxburghshire, Ayrshire and 

 Perthshire. In Ireland it seems to occur in all wooded 

 districts and is recorded from Howth near Dublin, Wicklow, 

 Cork, Kerry, Galway, Sligo, Westmeath, Cavan, Monaghan, 

 Louth, Down rarely, and commonly at Enniskillen and in

 Europe, North Italy, Southern Sweden, Livonia, the Ural 

 Mountain district, Siberia, Eastern Asia, Canada and the 

 United States.
