114 THE ENTOMOLOGIST, 



occurred not commonly on the river bank, but only at the edge of 

 the pine woods, P. var. la2:)ponica displacing it on the open bank. 



On my last day I essayed to secure Erehia disa, though I 

 knew I was far too late for it, exploring the ground between 

 Ebidal and the Skadavaara mountain, but unfortunately the sun 

 went in and I failed to turn it up. 



Returning to Bossekop that afternoon by kariol, I called as 

 promised upon my friends who had been so kind on the morning 

 of my arrival, the steamer leaving for Hammerfest about mid- 

 night. 



At Hammerfest I had to wait again one day for the steamer 

 to Harbin, en route to Narvik, so I occupied myself in looking for 

 larvae of Aglais urticce var. iwlaris. The difficulty was to find the 

 food-plant. Some of which at last I noticed in a back garden 

 yielded only small larvfie ; but after another search some more 

 clumps were discovered on the left bank of the river, leading from 

 the Storvand, which flows into the harbour towards the north 

 end of the town. On these the larvae were half grown, and I took 

 about fifty, of which I lost a considerable number through the 

 food-plant becoming mouldy while I was on the boat. I managed, 

 however, not without difficulty, in rearing a few. 



After an uneventful journey on board the " Midnatsol," on 

 the night of the yth July I slept at the Grand Hotel, Narvik, and 

 the next morning netted Erehia ligea commonly. C. var. stieheri 

 was also taken here, as well as G. optilete and Colias var. lap- 

 ponica. 



In -the afternoon I took train again to Abiskojokk where I put 

 up for two days, wishing to see if any other species had made 

 their appearance during my absence. All the species seen on 

 my first visit had disappeared completely. Visiting Bjorkliden 

 next morning I found G. optilete, Pieris napivR,r. hryonice, Erehia 

 ligea tending more to var. horealis, Brenthis p)ahs var. arsilache 

 and var. lapponica, Augiades comma var. catena ; and I also found 

 here some full-fed larvae of Aglais urtica var. polaris. The second 

 day was spent on the slopes on the way up to Lap-porten, 

 where I again got B. pales var. arsilache, C. palceno var. lap- 

 ponica and G. optilete, the last of which was here obtained in 

 perfect condition. There was a high wind as usual and little 

 sun, and this finished collecting as far as this journey was con- 

 cerned, and I returned home rid Boden, Briiche and Hallsberg, 

 taking the boat at Christiania for Newcastle, where I was held 

 up nearly two days by the local railway strike. 



The following is a full list of species observed and taken, 

 which altogether number thirty-six. 



Pieris hrassicce, L. — Seen at Mattmar. 



P. napi, L. — Several at Mattmar. Var. napcece ?. — Disenaaen. 

 YsiY.frigida, Scudd. — Males taken at Abisko and Narvik are with- 

 out spots or apical blotch, and would seem to be near, if not this
