146 LEPIDOPTERA. 



wet places, and moderately plentiful in the fens of Cam- 

 brido-esliire and Norfolk. Forty years ago it was common in 

 the marshes of Hammersmith, Putney, Plumstead, and else- 

 where on the banks of the Thames close to London, and 

 although these are now destroyed it still lingers on any 

 suitable portion of the river banks. In Kent it is found, in 

 addition, on the coast, where reeds grow ; also rarely in suit- 

 able spots in Sussex, Devon, and Cornwall ; probably more 

 commonly in the extensive "moors " of Somerset. Formerly 

 abundant at Whittlesea Mere and Yaxley Fen, and still, 

 besides the existing fens, in suitable spots, very locally, in 

 Cambridgeshire, Huntingdonshire, Essex, Suffolk, Norfolk, 

 and Lincolnshire ; there is also one locality in Cheshire. I 

 know of no others in the United Kingdom. 



Abroad it is found in many parts of Northern and Central 

 Europe, and in the Ural Mountain district.
