say. It may be a Callerebia, but all these newly- 

 discovered Central Asiatic species are at present so rare 

 that their classification must be deferred till we know

E. patagonica, Mabille, is unknown to me, and may 

 belong to another genus, but if not, it will be the only 

 species in South America, as E. vesagns, Doubl., and 

 E. boisdavalii, Blanch., from Chili, are not Erebias, but 

 belong to the genus Ncosatgrus, Wallengren.
