24 A JOURNEY TO FIiVMARK. 



yery limited localities, such as Colias Palce.no, Lyccena Op- 

 tllete, Argynnis Pales, var. ArsHache, &c. Only four 

 species occur likewise in the South of Europe, Polyoinmatus 

 Phlceaa, Lyccena Argus, Vanessa Urticc^ and Hesperia 

 Comma. Many of these 16 species put on a rather different 

 appearance in the far north from what we find in the same 

 species from Central Europe, but yet cannot be separated 

 from them specifically, as used to be done formerly in some 

 instances. The influence of the northern climate does not 

 affect all the species in the same way, since whilst some are 

 darker, others have a decidedly paler colouring. In refer- 

 ence to the size, most of the species are rather smaller, but 

 some are at least as large, sometimes even larger, than the 

 corresponding species in Central Europe. A third of the 

 Rliopalucera of Finmark, i. e., 8 species, belong to the 

 genus A7^gynnis, — indeed, more than a third, if, as many do, 

 we repute A. Pales and Arsilache distinct species. Three 

 species of Pieridoi occur in Finmark, 1 Pieris and 2 of 

 Colias; 4 Lyccenidce, 2 of Polyommatus and 2 of Ly- 

 ccena; 10 Nymphalidce, 1 Vanessa, 1 3Ielitcea, and 8 

 of Argynnis ; 6 Satyridce, 3 of Erehia and 3 of Chio- 

 nobas; of the Hesperidce only 1, Hesperia Comma. 



The richness of the Rhopalocerous Fauna of Finmark is 

 surprising, when w^e consider that in Labrador, which has 

 been well explored for diurnal Lepidoptera, only 17 species 

 have been found. Menetries enumerates in " Von Midden- 

 dorf's Travels in Siberia," 21 Rhopalocera, of which 1 

 species, Erehia Edda (allied to Emhla) is new^, and 6 of 

 which also occur in Finmark (^Colias Palceno, Argynnis 

 Aphirape, Fr/gga, Pales and Chionobas Noma, as also 

 the Ai-gynms Polaris), which at any rate we did not meet 

 with. But we may with great certainty assume, that many 

 yet of Zetterstedt's 77 Lapland Mhopalocera will be found 

 to occur in Finmark.
