butterflies taken by them in Norway from June 20 to July 22, 
during the past summer at Szterstiéen and Bolkesji, about 
60° 12’ N., and Bossekop, 69° 50’ N. It appeared from the 
exhibit that it would have been better to collect a month or 
so earlier, especially in the more northern locality visited. It 
was also seen that northern races of butterflies and moths 
were apt to differ a little from those of the mid-European 
fauna, but that various named varieties supposed to be 
characteristic boreal representatives of their species, were 
often rather aberrations, and not the dominant northern type. 
This was the case in Vanessa urtice, Hrebia medusa, E. ligea, 
etc. ; on the other hand, as in Brenthis selene, var. hela, the 
entire local race was of the variety. 
The series exhibited comprised the following species :— 
1. Colias paleno, from Seterstéen and Bossekop. The 
northern specimens with distinctly narrower borders than 
the southern ones. 
2. Vanessu urtice. About half the specimens bred were 
shown, the larve from Kaafiord near Bossekop. Many 
specimens resembled English ones, though the average was 
much darker than that of English examples. One or two 
approached var. polaris, which was not actually represented. 
Polaris appeared therefore not to be a northern race, but an 
aberrant form no doubt more frequent there than in England. 
3. Brenthis aphirape, chiefly var. ossianus, Herbst. Variable 
in intensity of markings and the amount of silvering beneath, 
but presenting no marked aberrations, such as are described by 
Meves (Entom. Tidskrift, 1894). 
4, Gneis jutta, Seterstien. A large race exceeding 2} inches 
in expanse and varying from a form without spots to one with 
six spots on the forewings and four on the hindwings, in some 
with a trace of white pupils. 
5. Hrebia embla from Szeterstéen, showing considerable varia- 
tion, but no extreme examples. 
6. Hrebia ligea. Four series respectively from Kaatfiord, 
69° 50’ N., July 20; Tromsdé, 69° 40’ N., July 24; Bodi, 
67° 15' N., July 25 ; Trondjhem, 63° 25’ N., July 27. 
The Tromsé specimen very worn, those from Trondjhem 
very fresh, though taken 3 days later. The Kaafiord
