14 THE ENTOMOLOGIST. 



the sun shortly before noon on July 23rd at Kistrand, turned out to 

 be this species. Anyone acquainted only with Scotch specimens 

 would not recognize this one as P. hyperborea, but it agrees well with 

 examples from Lapland in the National Collection. 



Plusia hochemcarthi. — Common at Laxelv. I did not see it else- 

 where.' 



Anarta melaleuca. — This beautiful little species was abundant 

 everywhere on moors in the Porsanger district, resting on rocks, and 

 flying wildly off as one approached. 



A. zetterstedtii. — Abundant on the dolomite screes at Kolvik, flying 

 briskly in the sun, and settling on the bare rock. In dull weather 

 not a specimen could be seen, or even kicked up. The food-plant is 

 no doubt Dryas octopetala, which is the only plant except grass 

 growing in its haunts. 



A. richardsoni. — Not uncommon in the same locality as the last 

 species, and, like it, flying freely in the sun. 



Gnophos sordaria. — A light grey form of this was abundant at 

 Kolvik ; the white dolomite rocks were answerable for the colour. 



Psodos coracina. — Abundant everywhere in the Porsanger Fjord. 

 The specimens varied from black to almost white, the colour depend- 

 ing upon the nature of the strata the examples frequented. 



Larentia casiata. — Common everywhere. 



Melanippe hastata, var. hastulata. — Not uncommon at Bossekop. 



M. montanata. — Common at Laxelv. 



M. fluctuata. — Generally abundant. 



Coremia munitata. — Perhaps the most abundant Geometer I saw 

 north of the Arctic Circle, occurring everywhere abundantly ; a 

 small form. 



Cidaria polata. — A few examples in most localities. 



C. frigidaria. — Common at Kolvik. 



In the course of my two expeditions to Scandinavia I came 

 across, in more or less abundance, all the Diurni occurring 

 there which are not found in Central Europe, with the exception 

 of two, Melitcea iduna and Brenthis chariclea. As these species 

 are both very local and imperfectly known to lepidopterists, it 

 may not be out of place to say a few words about them. 



Melitcea iduna is apparently to be got with certainty at 

 Kvickjock, in Swedish Lapland, and has been reported from 

 Abisko, but this latter report requires confirmation. In Arctic 

 Norway it has been taken by various entomologists in the 

 Sydvaranger Fjord, and W. M. Schoyen took one example (a 

 female) at Laxelv, in the Porsanger Fjord, on July 18th, 1879. It 

 is described in Seitz as being found in Lapland and Central and 

 North-east Siberia, where it flies in early July in abundance in 

 barren alpine meadows, at altitudes of from 6-8000 ft., in com- 

 pany with M. cinxia and Brenthis aurinia. 



Brenthis chariclea is one of the rarest, if not the rarest, 

 of European Diurni. The only records I can find are that 

 Staudinger took twelve examples at Alten, July 17th to 26th, 

 1860, where it was afterwards found by Sandberg. In 1878
