320 LEPIDOPTERA. 



Yorkshire, and even Cumberland ; yet it does not seem to have 

 been observed in Scotland except in two instances of single 

 specimens, supposed to have been introduced. In Ireland it 

 has been found in Wicklow, Waterford, Cork, Kerry, and 

 Galway. Abroad it is common throughout the temperate 

 portions of Northern Europe, Central Europe, Piedmont, 

 Northern and Eastern Turkey, and Southern Eussia, 

 possibly even extending far into Asia, since a form brought 

 from Japan, and known as jJseud-ahietis, is probably nothing 

 more than a variety of this species.
