Colias Edusa neat' Darlivffton. — On the 11th of June, I had the pleasure 

 of seeing Colias Ediisa on the wing for the first time in my life. It was a male 

 specimen, which rose almost from under my feet, as I was walking along the 

 bank of the river Tees near the town. It circled round me twice, quite close, and 

 gave me a good view of both upper and under sides, and then, no doubt thinking 

 tliat it had done all that could be expected of it, it pelted off as hard as it could. 



Several have since been taken here, and many more seen. On June 17th, I re- 

 ceived a nice male alive, taken by my brother near Barnard Castle, with the informa- 

 tion that about thirty had been seen, and that it was quite plentiful. The next 

 news I heard of it was at Wolsingham, a high moorland district, about twenty miles 

 to the north of this ; there I saw Mr. A. Pickard, who beat everything I had pre- 

 viously heard by the startling information, that about 100 had been seen in that 

 neighbourhood, and a good many of them taken ; some in the valleys, and some all 

 over the moorland, even on the highest hills, which are very bleak in that part of the 

 country ! 



Where can they all have come from ? Some of them are very fine and fresh 

 looking, but I think they are all hibernated specimens. 



Some years there have been two or three taken near here in August, in very 

 favourable seasons, but such an invasion as this in our part of the world was never 

 heard of before. — Jony Sang, Darlington : June 2'->lh, 1877.
