Fubruary, 1899.] 25 



it occurred in 1896 at the end of July. At Bodo, on July 25tb, it 

 was rather passee, and very much so at Tromso on the 24jth, where it 

 was very abundant ; but at Trondhjem, though so much further south, 

 it was only just emerging on the 27th, only three, but perfectly fresh 

 specimens, being taken, these appeared during a solitary gleam of 

 sunshine lasting only a few minutes. 



This species then certainly emerged earlier in the north, at 

 Tromso, than in the more southerly latitude (by several hundred 

 miles) of Trondjhem. Sexual dimorphism is much less marked in 

 these Norwegian Li^ea than in central European varieties, and in 

 those from Kaafiord is reduced to evanescence. A large proportion 

 of the specimens from this locality are very small, as small or smaller 

 than Euryale, var. ocellaris, but are still Ligea, with no tendency to 

 resemble ocellaris. 



Taken altogether, the most common butterfly at Bossekop, the 

 only one perhaps that could be called common, was Lycwna Optilefe ; 

 this seemed to be still emerging on our arrival about July 10th, and 

 whenever the weather was suitable, was abundant on the moors 

 amongst Vaccinium uliginosum, which I suppose to be its food-plant ; 

 L. Argus was not uncommon in suitable localities, but was not seen, 

 probably not emerged, on our first arrival. A few specimens o£ L. 

 Icarus were also seen. 



Colias Hecla was very local, on flats by the river and a few other 

 places, one being taken at Kaafiord, in the village, at a distance from 

 any place resembling our ideas of its proper habitat as gathered at 

 Bossekop ; unfortunately, the weather was not favourable to our 

 seeing many specimens, and those we met with were worn, usually 

 extremely so. 



Pieris napi, var. hri/onice, was not very rare, but was much worn, 

 the form was a very fine dark one, many of the males even having the 

 veins widely black. 



Several specimens of Vanessa Antiopa and urticce were seen, and 

 the larvfe of the latter were abundant at Kaafiord. 



With the Argynnes we were very unlucky : Selene was common, 

 usually worn, extremely variable from something near the type to 

 small dark specimens, some of which were clearly referable to var. 

 Sela. 



Hiiphrosyne, Frigga, and Apliirape were represented by single 



worn specimens, and Freija by three ghosts. Though we visited what 



I take to have been the locality i-ecorded by Staudiuger for Chariclea
