on the inferiors, and I find that almost all the European examples in 

 the National Collection are of this form, which one must therefore 

 conclude should be the typical European form in this respect. 

 Lefebvre's specimens, which he states came from Iceland — where we 

 now know C. hecla does not occur — were no doubt from Arctic 

 America, judging by the figures. The variation of the hind wings in 

 my specimens takes two forms, one is the extra distinctness of the 

 blotches, and this is emphasized in those specimens which have an 

 extra dark marginal band, or dark ground colour to the wings. This 

 form I have figured on Plate xiii., figs. 5 and 7, and propose for 

 it the name clistincta, n. ab. In the other form the lower four 

 blotches are suffused with the ochreous ground colour of the wings, 

 and they thus become much less distinct; for this form (see Plate xiii., 

 fig. 6) I propose the name oclirea-suffusa, n. ab. 



A few of my females have the base of the superiors with dark 

 suffusion ; there are specimens of this form in the National Collection, 

 a suitable name for which appears to be obscura, n. ab. (see 

 Plate xiii., fig. 8). There is a good deal of variation in both sexes 

 in the shape and size of the discoidal spot in the centre of 

 the superiors ; in the males in some cases it is a narrow line, 

 in others it is as broad as it is long. Lefebvre describes and 

 figures this spot in the female " with an orange centre " ; my 

 specimens generally agree with this, but in about ten per cent, 

 the orange centre is wanting, which thus might be called nicjro- 

 imnctata, n. ab. 



Buinicia jjhlceas, var. hyjJOijhlcBas. — This fine form I had expected 

 to meet with freely, but only saw two males, both of which were 

 captured at Laxelv ; one of them is ab. cceruleopunctata. 



Polyommatus optilete. — Abundant at Laxelv. Amongst Vaccinium. 



Arjlais urticce. — The only larvae I saw were a colony at Borselv, 

 which I managed to bring home as pupae ; these emerged in the 

 middle of August as fine dark examples, not, however, so strongly 

 banded as some I obtained at Abisko last year ; they were, of course, 

 all tending towards var. ^iolaris. 



Brenthis ijales, var. lapponica. — Fairly common at Laxelv and 

 Kistrand, but not so abundant as I expected to find it. 



B. freija. — Not infrequent at Bossekop, and in good condition. 

 In the Porsanger Fjord it was not common ; I saw one or two worn 

 examples at Borselv on July 7th, and perhaps half a dozen others 

 a week later at Laxelv.

BY THE WAY. 



We have read with such attention as it deserves the proposal 

 of the Entomological Society — as Verrall said, being the oldest 

 Society of the kind it lacks all need for the minimising 

 appange " of London" — to the infant International Congress of 

 Entomology, respecting priority of nomenclature ; and we have
