From pilicornis and inermis this species may be distinguished at once by its 

 narrow form, the much shorter and less conspicuous clothing of the head and thorax, 

 and the steel-blue, not black, abdomen. Long., 7—8 mm. 



Criccieth, Barmouth, and Towyn, N. Wales. Curtis's specimen 

 came from Ambleside, Westmoreland, and there is a ? in the National 

 Collection, mixed with inermis, from Perthshire. 



I have to thank Mr. Nevinson for the female from which I have 

 drawn up the above diagnosis. The S was taken by my nephew, Mr. 

 F. Saunders, at Barmouth in June, 1884 ; this specimen has been 

 for some years in the collection of the Eev. P. D. Morice, to whom I 

 gave it in mistake for a cT cserulescens, it having been mixed in my 

 collection with that species.

NOTES ON CERTAIN DIPTERA OBSERVED IN SCOTLAND DURING 



THE YEARS 1898-99. 



BY COL. J. W. YEEBURY, late R.A., F.Z.S., &c. 



I respond to the wish that I should give some account of my 



captures during the years 1898-99. The former records of most of 



the species mentioned are to be found in " The Scottish Naturalist," 



and "The Annals of Scottish Natural History," and while calling 



attention to these, I have supplemented them by giving my own 



experiences. 



Laphiiia flava, L. 



The first record of the occurrence of this insect within the limits of 

 the United Kingdom was made by Dr. Vice (The Scottish Naturalist, 

 Vol.2 [1873-74]), viz., that of a ? specimen taken in Strathdon, Aber- 

 deenshire, in August, 1872 or 1873, and the only subsequent record is 

 the following by the Rev. E. N. Bloomfield (Ent. Mo. Mag., 2, vol. ix, 

 138 [June, 1898]), who reports the capture of a pair at Banchory, 

 Aberdeenshire, in September, 1889. At a meeting of the Ent. Soc. 

 Lond. held October 5th, 1898, 1 exhibited a pair taken at Aviemore in 

 July, 1898, and this year (1899) I took another ? in the same locality 

 on July 10th ; besides the above, a single specimen is to be found in 

 the Edinburgh Museum, taken by Mr. L. Hinxman in the Eothie- 

 murchus Forest, in the year 1895. 



The above list (seven specimens) exhausts all the captures I can 

 trace, and it will be noted that all are from localities on the flanks of 

 the Cairngorms. As regards habits I have learnt but little, still it 

 may be worth while to put on record such points as I have noted 

 regarding the three specimens taken by myself : —
