348 LEPIDOPTERA. 



shire ; Cambridgeshire, Suffolk, Norfolk, and Lincolnshire ; 

 apparently Yorkshire, where it is very local, is its northern 

 limit in these islands. In Wales, where I have taken it in a

 occurring in Kerry, Cork, Waterford, Limerick, and Galway. 

 Abroad it has an extensive range through Central Europe, 

 the temperate portions of Northern Europe, the Northern

 the districts of the Altai range, the Corea, and Japan ; in the 

 last-named country varying very greatly in size.
