12 THE ENTOMOLOGIST. 



beyond, within two or three feet of the farther edge of the scrub. The 

 small locality in which I found my specimens is figured on Plate xii. ; 

 they flew over the slopes which are in the front of the plate, at a height 

 of from 50 ft. to 300 ft. above the level of the Fjord. The dark 

 patches here are composed entirely of Dryas octopetala. 



I do not know a good figure of this species, and have therefore 

 given a photograph of it on Plate xiv., figs. 5 and 6, together with its 

 nearest arctic ally B. freija, figs. 1, 2, and 3, to which it has a close 

 superficial resemblance ; the two can, however, be at once distin- 

 guished by the T marks in the outer margins of the inferiors in 

 B. polar is. 



B. frigga. — This species was common but worn at Laxelv from 

 July 11th onwards. So much so, in fact, that I could have netted 

 two dozen or more examples on July 12th had I been so disposed, but 

 unfortunately the majority were too battered for cabinet specimens, 

 and I had to content myself with about a dozen altogether. The Por- 

 sanger examples have the pale central fascia on the under side of the 

 inferiors much more suffused with reddish brown than my Central 

 Sweden specimens ; this form is noted by the original describer of the 

 species, Thunberg, whose type- specimens came from Lapland. 



CEneis noma. — I found this species just emerging at Bossekop 

 during the last day or two of my stay, and saw three or four speci- 

 mens. At Kolvik it was common on the rocky lower slopes of the 

 dolomite, and a few worn examples were seen at Laxelv. 



Authors, including Kane and Lang, have described the type of 

 this species as having two ocelli on each of the front and one on each 

 of the hind wings. The original description and figure by Thunberg 

 in ' Insecta Suecica,' however, gives three ocelli on each of the front 

 and one on each of the hind wings, and of course this form must 

 thus be taken as the type in nomenclature. 



My Porsanger series of fifteen males and twenty-one females in- 

 cludes seven females, but not any males, of this form. Of the three- 

 ocelli form which Kane and Lang have treated as the type, I have 

 six males and three females ; for this form I propose the name of 

 tripupillata n. ab. Of the forms I obtained last year at Abisko (see 

 ' Entomologist,' vol. xlv. p. 68), the series includes four males and 

 four females of ab. bipupillata, Sheldon; one male of ab. unipupillata, 

 Sheldon ; three males of ab. obsoleta, Sheldon ; and two females of 

 ab. pallida Sheldon ; in addition to these I have two ab. ochracea, 

 Aurivillius ; and one male and three females which have an excess of 

 ocelli over what obtains in Thunberg's type. I believe in certain 

 Scandinavian localities forms with a variable number of ocelli in 

 excess of those of the type are not uncommon, and the most con- 

 venient way of dealing with these seems to be to call them all ab. 

 excessa, n. ab. 



Erebia medusa, var. polaris. — One would naturally expect to find 

 this to be one of the most widely distributed of Arctic Diurni, but 

 except at Laxelv I did not see it ; there it was common and in good 

 condition at the time of my visit. 



E. disa. — This fine species was one of the special objects of my 

 search. At Bossekop Staudinger apparently found it not infrequent, 

 and one forms the opinion on reading his account of the Lepidoptera
