"Newman observes of this species: — 'The moth appears 

 on the wing in July, and has been brought in great numbers 

 from Iceland. It flies during the day, and may sometimes 

 be seen flying in crowds about the flowers scattered sparingly 

 over the surface of the ground.' It is, however, equally the 

 fact that it is on the wing by the middle of June, as, for 

 example, I captured it at Akureyri on the 19th of June this 

 year ; and as young friends there collecting on my behalf had 

 a few then in store for me, it is reasonable to suppose that it 

 had first been seen at all events a week previously. We shall 

 probably not be far wrong in asserting that the period when 

 it occurs in the best condition and in the greatest numbers is 

 from about the middle of June to the middle of July. Noctua 

 confiua is met with, but much more sparingly in June, but 

 becomes particularly abundant and is quite the commonest 

 Noctua just at the time that Crymodes begins to be scarce. 

 Both species agree in this particular, — in the very variable 

 tint and markings of the fore wings. Both kinds greatly 

 affect the wild thyme, on which they are often found asleep; 

 Crymodes, however, is the more active of the two, and 

 is frequently to be seen flying about, as Mr. Newman describes, 

 or hovering round the flowers. 



It was at Aknreyri, at the southern extremity of the Eyja- 

 fjordr (28 miles from the north coast of Iceland and the 

 Arctic Ocean) that I found this moth in the greatest 

 numbers. My observations on the present occasion will 

 accordingly have reference chiefly to its different types, as 

 occurring there on Viola tricolor, Galixim saxatile, Thymus 

 serpyllum, Sileiie acaulis, Dryas octopetala, &c. Out of upwards 

 of 350 specimens collected by myself, and by the young
