322 [ Jul >'' 



The third butterfly observed, which Dr. Jordan names Chionobas 

 Jutta, adding that it " settled on a slab of rock as usual," was, I have 

 no doubt, Satyrus Semele, which, in August, flies commonly on the 

 rocks at Bergen, whereas Chionobas Jutta has never been found there. 

 Jutta, moreover, does not fly on rocks or stony ground, but exclusively 

 on moors, amongst fir trees, on the stems of which it chiefly settles. 

 When Dr. Jordan further speaks of having taken Chionobas Jutta at 

 Jerkin, Dovrefjeld, and compares its habit with that of the alpine 

 Chionobas Aello, he has again, without doubt, confounded Chionobas 

 Noma, which is the species of Dovrefjeld, with Jutta. This last 

 named species has, up to the present time, not been found there, 

 though many Entomologists, both Norwegian and from foreign 

 countries, have, at different times, collected very assiduously in that 

 interesting locality. 



The fourth butterfly mentioned by Dr. Jordan, which he not only 

 observed, but actually caught, he calls " Pararge Uiera, a small dark 

 and beautiful specimen." Yet I have no hesitation in saying that 

 again he has wrongly determined the species, as Pararge Uiera is 

 never on the wing at that date (August 20th) ; it is an early species, 

 only to be found in May and June, or, perhaps, a few worn and 

 weather-beaten specimens in July. I have no doubt that what Dr. 

 Jordan did take was a $ Pararge Mara, which species flies just at that 

 time on the cliff-sides at Bergen and elsewhere in our country, and of 

 which the males are generally both small and dark-coloured, so that 

 they may be easily confounded with Uiera by an observer who has not 

 had much experience of the two species. 



The fifth butterfly mentioned, Lyccena Icarus, is common through- 

 out Norway, and is, no doubt, rightly named. 



The Geometrce and Micro- Lepidoptera mentioned are common 

 species, and have nearly all been already observed in the same locality. 

 As for Platyptilus Fischeri, mentioned also by Dr. Jordan at p. 42 of 

 the same volume, " common as far north as Throndhjem in Norway," 

 I may state that this species is common much further north, and even 

 occurs in Finmark at 70° latitude. 



Mr. Baker's notes on the Cranibi collected by Dr. Jordan are of 

 more interest, a3 the determinations of the specimens do not arouse 

 my suspicions as to their correctness. 



The only point which strikes me is that Crambus cerussellus (one ? ) 

 is said to have been taken at Throndhjem, as this species had not been 

 observed further north than Christiania. As for Crambus truncatellus
