EREBJA. 227 



fcrred to use this name provisionally in the present work, as 

 the type of Maniola (Schrank), is somewhat doubtful ; and the 

 latter name may ultimately have to be used for some other 

 genus. 



Eyes naked; antennae slender, with a rather long club. Fore- 

 wings with only the sub-costal nervure much dilated at the base 

 Wings rounded or oval, sometimes slightly dentated, generally 

 bro.vn, with a fulvous (and sometimes macular) sub margina. 

 band containing black or ocellated spots. 



These Butterflies are known as " Mountain Browns," and 

 are very numerous in the mountains of Europe and Asia. 

 As Britain, however, is situated in the north-west of Europe, 

 where Butterflies are less numerous than in any other part, 

 and as our mountain systems are isolated, both from the Alps 

 and the Scandinavian mountains, our highland fauna is very 

 poor. 



The only truly mountain Butterfly in Britain is Erebia cassiope 

 (Fabr.).
