LEPIDOPTERA OF JEMTLAND AND LAPLAND. 65 



of Gillingham, Kent, writing to me in reference to favicolor, 

 remarks: — "In their habitat it is quite common to take favi- 

 color and pallens in cop. I have three such pairs taken this 

 year [1911] ; also a few insects which I am unable to place 

 either with favicolor or pallens." Perhaps other entomologists 

 may have also met with such cross-pairings when in search of 

 favicolor ; if so, it is very desirable that the observation should 

 be recorded. 



LEPIDOPTEEA OF THE SWEDISH PROVINCES OF 

 JEMTLAND AND LAPLAND. 



By W. G. Sheldon, F.E.S. 



(Concluded from p. 27.) 



Callophrys riibi. — Worn specimens were frequent at Mattmar. 



Chrysophanus amphidamas var. obscura. — Abundant at Mattmar ; 

 some of the examples even at the time of my visit, June 4th, were 

 worn, but there was a good percentage of newly emerged ones ; the 

 butterfly was most abundant amongst sallow thickets on the edge of 

 the swamps, flitting about the bushes with a very Thecla-Yike flight, 

 and settling on them from time to time. I found ova not infre- 

 quently on the under side of the leaves of Polygonum viviparum. 



C. phlaas var. hypophlceas. — I found a single perfect example of 

 this fine form at rest on a bent of grass, at Narvik, on July 19th. 



Plebius argyrognomon var. agidion. — First seen at Abisko on June 

 29th, after which date it became common on the banks of the 

 tributary of the Abiskojokk, where Mr. Kowland-Brown found it in 

 1906, and which is in the park, but I did not see it elsewhere. 



Polyommatus optilete var. cyparissus. — The first example was 

 captured on June 29th : it was not common, but I did not work for 

 it, and only brought a few specimens home. 



P. icarus. — One female of the cceridea form was taken on July 

 16th : probably the species was only just emerging at the time of my 

 departure from Abisko. „ 



Aglais urticce. — Larvae were very abundant at Are, a few of which 

 I took to x\bisko ; they pupated there, and emerged on my way 

 home ; the whole are very full-coloured specimens, with the central 

 spots large, and one is distinctly var. (ab. '?) polaris. As Abisko was 

 until a few years ago absolutely without cultivation, I scarcely 

 expected to see this species there : however, a few days after my 

 arrival I came across two battered imagos, and thereupon made a 

 search for nettles, a few patches of which I succeeded in finding, in 

 the proximity of some ruined buildings ; one patch in a sunny corner 

 was covered with several hundreds of larvae, a number of which I 

 brought home. These produced some fine var. polaris, which 

 emerged from August 8th to August 18th. 



Brenthis aphirape var. ossianus. — This species was common at 

 Mattmar, and less so at Abisko. It is essentially a swamp species, and 

 I did not see a single specimen on other ground ; one of my examples
