has, I thiuk, disappeared. More than forty years ago it was 

 found near Plymouth, and more recently in other parts of 

 Devon, also near Bristol, and rarely in Sussex, Dorset, and 

 Cornwall. In Wales it was taken in Carmarthenshire thirty 

 years ago, and a few years later I found it in some plenty in 

 Pembrokeshire, but here after two seasons it became scarce 

 or else shifted its locality, and I cannot say that it can now be 

 found with certainty in any one of these localities. On the 

 other hand, it seems worth while to look for it in any hilly 

 district, of very poor pasturage, in the South-west. 



Abroad it seems to be found all over the Continent of 

 Europe except the coldest portions also in Bithynia, Southern 

 and Western China, India, Ceylon, and Japan.
