 affect such elevations as its congener sometimes reaches,"

 lower mountain-sides as well as in marshy spots in 

 similar localities.

EREBIA ^THIOPS. 



Some few years since, cethiops was considered an ex- 

 tremely rare butterfly, and even now cannot by any 

 means be spoken of as common. The most that can 

 be said is that it is not uncommon in many parts of 

 Scotland, and that it is taken in several localities in the 

 five or six northern counties of England, and commonly 

 at a few spots, such as Castle Eden Dene, in Durham, 

 and Grange, in Lancashire.
