Medusa S.V. (in mountain woods in May and June), Ligea L. (July, August, 

 in less elevated districts), or Euryale Esp. (on mountains in July and August). 

 Ligea, as is well known, is said to have been taken in Arran. The evidence to 

 that effect is, however, so unsatisfactory that we cannot in the meantime include 

 it in the list of Scottish insects. Mr. A. G Butler has shewn (Ent. Monthly 

 Mag., iv. 151) that Stephens has figured (111. Brit. Ent.) Euryale Esp. as the 

 male of his Ligea, said to have been taken in Arran. 



The other genera of this family are not so alpine, but still there are several 

 Central European and Scandinavian species, which might have been expected 

 to occur in Britain.
