NORWEGIAN LEPIDOPTERA. 13 



of that place, that it chiefly occurred in the large low-lying and very 

 wet swamp behind the church ; and acting on this glue I passed the 

 best part of four days therein, pretty well up to my knees in water 

 most of the time, with the result that in that period I obtained one 

 specimen, which was accidentally kicked up on June 14th on a wet 

 moor between the Ebydal Eoad and the Alten Eiver. On June 19th 

 it occurred to me that either Staudinger's swamp had changed since 

 his visit, or that his account was wrong ; and taking a wide sweep 

 I investigated the moors between the Ebydal Eoad and the Skadavaara 

 Mountain. Here, on this day, I found E. disa locally quite common, 

 taking nineteen specimens in perfect condition, and on the following 

 day twenty-six more. It frequented a rather wet track overgrown 

 with Vacciniwn, with a certain amount of a fine grass much re- 

 sembling Aira cespitosa. 



It was fortunate that I stumbled across the species at Bossekop, 

 for although Schoyen appears to have found it common everywhere 

 in the Porsanger Fjord, with the exception of two or three examples 

 seen three or four miles up the valley of the Laxelv, I did not see the 

 species in this district. 



My series taken at Bossekop consists of thirty-seven males and 

 nine females. Of these thirty males and six females agree with 

 Thunberg's description of the type in having on each superior four 

 blind ocelli. Four males and three females have an additional ocellus 

 on each superior ; for this form I propose the name of ab. addenda, 

 n. ab. (Plate xiii., fig.' 3) ; whilst three males have the ocelli very 

 much obscured and reduced in size, ab. obscura, n. ab. (Plate xiii., 

 fig. 2.) 



E. lappona. — This is probably the most abundant and widely dis- 

 tributed butterfly to be found in Arctic Norway, occurring commonly 

 in every locality I visited. The form is a very bright one, with much 

 brown on the upper surface. In certain examples of my series the 

 brown, of which there is in typical specimens a patch near the apex 

 of the front wings, extends to the bases. This very striking form I 

 have in both sexes from Porsanger and Alten, and propose for it the 

 name of brunnea, n. ab. Another form of variation is that two of 

 my Porsanger females have splashes of the brown which is found on 

 the under side of the superiors, on the under side of the left inferior. 

 E. lappona was even to be found round Hammerfest. I spent two 

 cloudless days — June 24th and 25th — wandering over the desolate 

 mountains there, during which the only Lepidoptera seen were a few 

 examples of this species. 



Hesperia andromedcz. — I saw a few examples of this species at 

 Kolvik, and captured five. They frequented the same description of 

 ground as Brenthis polaris, but higher up ; in fact, on the top of the 

 dolomite hills, which rose out of the fjord 500 or 600 ft. 



Amongst the Heterocera observed were : — 



Anthrocera exulans. — Two specimens taken at Kistrand on July 

 23rd. These are somewhat worn, and thus one cannot well say 

 what form they represent, but they are rather small examples, with 

 pale red markings. 



Pachnobia hyperborea. — A grey Noctua, captured flying freely in
