the genus Erehia. 337 



confined in their range to the mountains of Southern 

 and South-eastern France. The former seems most 

 nearly alhed to nerine, the latter to evias, but both are 

 well-marked species, and seem to be subject to little 

 variation. 



E. afra, Esp., ?ind dalmata , God., are by Von Gumppen- 

 berg considered distinct from each other, but Staudinger 

 places dalmata as a variety of afra, and the specimens I 

 have seen from the Miitzell collection differ only in their 

 rather larger size and less distinct marking below. It 

 must be either very local or very rare, as so good a 

 collector as Josef Mann never got it in three summers 

 which he spent in Dalmatia, but it is said to occur at 

 Sebenico and Obrova in that country. Christoph also 

 notes its occurrence in the mountains near Askabad, in 

 North Persia, and treats it as a var. of afra ; afra, 

 however, is a very distinct species from any other, and 

 is found in South-eastern Eussia, as well as in Turkestan 

 and North Persia. Its nearest ally seems to be 



E-imrmenio, Boeb. — A large and distinct species, which 

 is found in Eastern Siberia as far south as Kiachta and on 

 the Upper Amur region. It seems, like afra, to be an 

 inhabitant of lowland and not of alpine districts. A 

 form of it without ocelli is described by Graeser as 

 inocellata. 



E. lajjpona is one of the most distinct and commonest 

 species in the high Alps, P3Tenees, and Scandinavia, 

 and occurs also in the Altai, but not in any intermediate 

 mountain ranges, or in Arctic America or Asia. This is 

 a curious instance of sporadic distribution with general 

 but no marked local variation, for the two named forms 

 of this, pollux, Esp,, and sthennyo, GrasL, are hardly 

 worthy of separation. Though the latter seems to be 

 the typical form in the Central Pyrenees and not to 

 occur elsewhere, it is not as yet a fixed variety, as 

 ordinary specimens of la-pyona are found with it. I have 

 also a specimen of lappona labelled " Balkan," but I do 

 not know on whose authority, and can find no published 

 record of its occurrence there. 



E. dabanensis is a species described by Erschoff from a 

 single specimen in his collection taken near Irkutsk. 

 From the figure it seems nearest to lappona, but with 

 ocelli on the hind wings, and may be a form of it or a 

 distinct species.
