L. optilete, Knock. — Fairly abundant about its food-plant, Vaccinium 

 uliginosum, both at Saeterstoen and Bolkesjo. 



L. icarus, Kott. — Only one or two ; a more metallic blue tban the 

 English or continental type. Kailway bank at Saeterstoen.

Argynnis aglaia, L. — One or two noted at Bolkesjo. 



A. euphrosyne, L. — Very abundant everywhere, but not so finely 

 marked as Swiss specimens. 



A. selene, Schiff. — Equally common in both places. The railway 

 bank swarmed with them. 



A. aphirape var. ossianus, Hbst. — Abundant both at Saeterstoen and 

 Bolkesjo. Much smaller than the type, specimens of which I have 

 from Germany witbout tbe silver blotches on the under side. 



A.freija, Thnb. — One only, at Disenaaen, worn. 



A.frigga, Thnb. — Seven or eight, in poor condition, in a clearing 

 of the forest a mile or so above Bolkesjo. 



Erebia lappona, E. — Only one, in good condition, on the Blefjeld, 

 about 3500 ft. up. 



E. embla, Thnb. — Abundant at Disenaaen and Saeterstoen, but 

 mostly in bad condition, especially the males. This insect did not 

 occur at Bolkesjo, and appears to frequent low-lying marshes only. 



(Eneisjutta, Hb. — Rather more abundant than the foregoing, and 

 flying about with it, but although, up to the last, we continued to 

 take now and then a freshly emerged example — especially above 

 Bolkesjo, nearly 3000 ft. up — the great majority were sadly worn. 



Pararge hiera, Fab. — Common at both places, very small at Saeter- 

 stoen, and at both much darker than the Swiss type. 



P. egeria var. egerides, Stgr. — At Saeterstoen only. Rare. 



Epinephele hyperanthus, L. — A few only, and of a rather remarkable 

 form, most of the specimens showing a tendency to approach the 

 aberration arete of Ochsenheimer — almost black on the upper side, 

 with the eye-markings of the type entirely effaced ; on the under side 

 a slaty grey, with the pupils of the fore wing only faintly visible. This 

 species was taken at both Saeterstoen and Bolkesjo. 

 Camonympha pamphilus, L. — Very common. 



C. typhon, Rott. — Fairly common both at Saeterstoen and Bolkesjo. 

 Syrichthus centaurece, Rbr. — Moderately common on the big bog at 

 Saeterstoen, but not in the best condition. 

 S. malvce, L. — Common.
