LEPIDOPTERA OF JEMTLAND AND LAPLAND. 67 



steadier flight, and looks larger and brighter-coloured on the wing. 

 Tutt says (' British Lepidoptera,' vol. ix. p. 30) that " this species is 

 only recorded as feeding on Bubus chamcemorus," a very abundant 

 plant at Mattmar. 



B. eujjhrosyne. — Very abundant at Mattmar — in fact, the most 

 abundant butterfly there — and a few examples were netted at Abisko. 

 At Mattmar it frequented the rising ground at the edge of the 

 swamps. The great majority of the specimens seen were certainly 

 not var. fingal, though they were slightly darker than the type, 

 and one or two were so clouded with dusky scales that they 

 approached the variety, but they were not so dark as examples of it 

 I saw in the National Collection at Stockholm and in the British 

 Museum Collection. The Abisko specimens were quite typical. I 

 also captured one female at Narvik on July 19th. 



B. thore var. borealis — This species, which Mr. Eowland-Brown 

 found abundant at Abisko, was this year quite rare ; probably it was 

 not out at the date of my departure. It was first observed — a 

 single specimen — on July 10th. I obtained a pair on July 16th, 

 and I believe my German friends accounted for half a dozen 

 examples on July 12th. o 



Erebia lappona. — Common at Are, and equally so at Abisko, 

 where it was certainly the most widely distributed and abundant 

 butterfly. The forms from both localities are similar. On the under 

 side of the hind wings some of the specimens have a strong tendency 

 to lose the transverse lines = ab. polhix, though none of them quite 

 do so. On the other hand, one of the females has the space between 

 these lines filled in with dark coloration. The upper sides closely 

 resemble my Swiss specimens, except that in the majority of cases 

 the hind wings are entirely without ocelli, though in one or two 

 instances these are well developed. 



E. ligea var. adyte. — A few examples were seen up the valley of 

 the Abiskojokk, from July 10th onwards; the ocelli in these examples 

 are very small, and the red bands in which they are placed narrow. 

 A specimen netted at Narvik, on July 19th, has the ocelli very large 

 on both fore and hind wings, and the red bands broad ; it is quite the 

 brightest banded example I possess from any locality. Both this 

 and the Abisko specimens are small, expanding only 44 mm. 



E. embla. — This species is said by Scandinavian entomologists to 

 be only found commonly every alternate year, occurring freely in the 

 even years, I was therefore not sanguine of meeting with many 

 specimens. In this apprehension events proved that I was right, for 

 I saw at Mattmar two examples only, one of which, a male in fair 

 condition, I captured. E. emblof is, I believe, in an average season, 

 to be found during the last few days of May. 



CEneis jutta. — I was unfortunate in only seeing one example of 

 this species, which rose heavily out of the grass at my feet in the 

 Mattmar Bog on June 5th ; it was a female of large size, expanding 

 62 mm., freshly emerged, but slightly crippled. I searched carefully 

 and widely for further specimens, but without success, and can only 

 suppose that the species was not fully out, though it should have 

 been according to the records of previous observers.
