A JOURNEY TO FINMARK. 23 



meet with all the Rhopalocera which do occur in the neigh- 

 bourhood of Bossekop, since of Colias Palceno, which Zet- 

 terstedt formerly found very abundant there, we saw only 

 two specimens ; and Coenonympha Davus, L., var. Isu, 

 Thunb., M'hich Zetterstedt took near Bossekop, we did not 

 meet with at all. At any rate, I believe that the Lepidop- 

 terous Fauna of Finmark may be reckoned as at least 300 

 species, to which the Alten district will decidedly make the 

 richest contribution. 



Amongst the 24 Rhopalocera found by us, there are only 

 8 truly northern species, one of which, Chionobas Borey 

 Esp., is probably only a variety of another Ch. Taynpte^ 

 Hb. {Bootes, B.). Mo-Jt of these 8 species occur in 

 Scandinavia, thus south of the Arctic circle, though partly 

 then indeed on the higher mountains, as for example, Chio- 

 nobas Noma on the Dovrefjeld, in latitude 62" 10'. Ar- 

 gynnis Freija also occurs in the deep plains, even in latitude 

 65°. Four of these species also occur amongst the 17 

 known Rhopalocera of Labrador, namely, Ar^gynnis Chari- 

 clea, A. Frigga, A. Freija and Chionobas Taygefe, Hb. 

 (Bootes, B.). 



It should here be mentioned, that Labrador is an Ai'Ctic 

 country according to its climatic peculiarities, but certainly 

 not by position, since the most northerly point of Labrador 

 only reaches to 6P North latitude, and therefore is hardly 

 further north than the town of Bero;en in the south of Nor- 

 way. The Lepidoptera of Labrador are, indeed, mostly 

 from such localities as lie in the same parallels of latitude as 

 the north of England, Jutland, Schoonen and Courland. 

 Of the remaining 16 Rhopalocera of Finmark, two are only 

 found again in Europe on the Alps, Erebia 3Ianto and 

 Argynnis Thore ; both also occur in Siberia. Ten other 

 species also occur in middle Europe, though confined to only
