NOTES 117 



Scottish Naturalist to know that a brown-headed Smew was shot 

 on Loch-an-dorb, near Dava, by Mr Mackintosh, gamekeeper to 

 Capt. Ewen I. Brodie of Lethen, proprietor of Duncarn Shootings, 

 Nairnshire, on the 7th February last. I saw the bird in this town 

 after being stuffed, and think, from its being of a larger size than 

 the immature male I have in my collection, it was an adult female. — 

 Richard H. W. Leach, Inverness. 



Early Appearance of the Common Tern on the 

 Clyde. — I read with interest Mr George Stout's note on this 

 subject in the April number of the Scottish Naturalist. I may 

 add that on 1st February my wife, my niece, and myself saw two 

 or three Terns on the wing in Kildalloig Bay, between Davaar 

 Island and Davaar Point, where a considerable stretch of sand is 

 exposed at low water. Again on the 4th we saw a small flock of ten 

 or eleven. I have no doubt of their being Terns, as we were well 

 acquainted with them at Pentland Skerries. — J. R. Laurence, 

 Davaar Lighthouse. 



Additional records of Scottish Stratiomyidae, etc. — In 



a paper by the Rev. James Waterston and the present writer {Ann. 

 Scot. Nat. Hist., 1909, p. 91) forty species of Diptera belonging to 

 the families Stratiomyidre and Asilidre were recorded from various 

 localities in Scotland. I have now some additional records to make 

 from the Blairgowrie district of Perthshire. Two species of special 

 interest have to be mentioned: (1) Stratiomys furcata, Fab., ^, 

 2nd June 191 1. This is the only occasion on which I have seen 

 a Stratiomys alive, and I have no note of any Scottish record for 

 this species beyond the old one (1837) cited by Mr Grimshaw 

 under the name of S. riparia, Mg. {Ann. Scot. Nat. Hist., 1903, 

 p. 160). According to Verrall {British Flies, vol. v.), S. riparia, 

 Mg., is now considered a variety of furcata. (2) Bombylius canescens, 

 Mik. I have a good series taken in June and July during the last 

 three years. This interesting fly is fond of hovering over sandy 

 places on the hottest days of summer. 



Blairgowrie is an additional locality for the following species : — 

 Sargus flavipes, Mg., 9> 2 3rd August 1910; Chloromyia formosa, 

 Scop., <$, 1 6th June 1911; Microchrysa flavicornis, Mg., $, nth 

 June 191 1 ; Beris geniculata, Curt., $ , 16th June 191 1 ; Hcematopota 

 crassicornis, Whlbg., 2 £ <£, 21st July 1909; Tabanus sudeticus, 

 Zlr., $, nth July 1910; Thereva nobilitata, Fab., 6* ?> 1 6th June 

 1910; Dysmachus trigonus, Mg., £ $, not rare, June 1910-n, 

 taken with a large ? Spilogaster as prey ; Dioctria rufipes, De 

 several taken 2nd and 4th June 1911.
