20 THE SCOTTISH NATURALIST 



North-west Highlands and Skye. 

 No record. 



Orkney. 

 A winter visitor, 



Shetland. 

 A rare winter visitor. 



As will be seen from the foregoing, the Gadwall is a 

 scarce winter visitor to almost every part of Scotland and 

 breeds irregularly in isolated localities. Its trend of 

 advance seems to be from the east, and an interesting point 

 about it is that nowhere in Europe has it been recorded as 

 breeding in very large numbers, as, for example, does the 

 Mallard. So far, its position in this country as a breeding 

 species seems to be very unstable, and it will be interesting 

 to see whether it settles down and colonises the whole of 

 Scotland. Its inconspicuous plumage and retiring habits, 

 no doubt, lead to its being in many cases overlooked, but 

 there seems to be no doubt that it is now, and may remain 

 for some time to come, one of our rarest breeding Duck, 



Glaucous Gulls in Kinross-shire. It may be of interest 

 to record the fact that two Glaucous Gulls {Lams glaucus) circled 

 over a field adjoining my house on the morning of the 21st of 

 December 1 9 1 9. Both were adults, for they showed no dark markings 

 and their wings were entirely white. C. C. Reid, Kinross. 



Oxygrapha (Leptogramma) niveana in East Lothian. 



I have pleasure in recording the occurrence of this interesting 

 moth in East Lothian, a specimen having been beaten by me 

 from birch at Tyninghame on 3rd October 1919. I have shown it 

 to Mr Durrant at the British Museum, and he confirms my 

 identification. Barrett {Lepid. Brit. Isles) was not aware of any 

 locality for the species south of Perthshire. Alice Balfour, 

 Whittingehame. 



Osphenomyia rufibarbis, Mg., in Atholl. Among some 

 Diptera collected by my friend Mr A. J. Meacher of Marlee, 

 Blairgowrie, during the past summer, and sent to me recently for 

 my collection, I was delighted to find a very fine female of this 

 interesting Bot-fly infesting the Red Deer. It was taken by Mr 

 Meacher close to the summit of Carn Liath (3193 ft.), a spur of 

 Ben-y-Gloe, on the 8th July 1919. The day was excessively hot, 

 and the fly was noticed settled on a stone. I think this is the second 

 record of the species from Perthshire. A, E. J. Carter, Monifieth,
