ON SOME NEW AND RARE SCOTTISH 



DIPTERA. 



BY A. E. J. CARTER. 



As our knowledge of Scottish Diptera is but of a scanty 

 nature I make no apology for publishing the following notes 

 on species I have recently identified. Some of those here 

 noticed may be found afterwards to be common and 

 generally distributed, but this can only be determined by 

 further work ; meanwhile, and as a help towards that end, 

 the publication of such records as we possess seems desirable. 

 The specimens taken by my friend, the Rev. James 

 Waterston, B.D., B.Sc., as afterwards mentioned, as well as 

 the whole of his large and valuable collection of Scottish 

 Diptera, have been given to me by him ; and when the 

 material which he has brought together from many different 

 localities is worked out, the result will be, without doubt, a 

 very great accession to our knowledge of the Dipterous 

 Fauna of Scotland. 



1. MYCETOBIA PALLIPES, Mg. A 3 taken by Mr. Waterston on 



Blackford Hill, Edinburgh, 6th August 1906. I have no note 

 of any British records. The species, I think, must be rare, as 

 I have never taken it myself nor seen it in other collections. 



2. ORPHNEPHILA TESTACEA, Ruthe. A species of the very greatest 



interest to students of Diptera, requiring not only a genus but 

 a family to itself. Mr. Waterston captured a $ at Whiting 

 Bay, Arran, in September 1906. I have only one other 

 Scottish locality Bonhill, where it has been taken by Mr. 

 Malloch ("E.M.M.," 1907, p. 87). 



3. RHAMPHOMYIA CULICINA, Fin. (new to Britain). I have had 



this species in my collection for some years as doubtful cuh'dna, 

 and am now able to record it, as my specimens agree in every 

 respect with the careful description given by Dr. Lundbeck in 

 the recently published Part III. of his valuable "Diptera 

 'Danica." The ? is very like the ? of variabilis, Fin., but is 

 easily separated by the thorax having two stripes (Lundbeck 

 says "slightly visible," but quite distinct in my specimen), and 

 by the presence of a row of acrostichal bristles which are want- 

 ing in variabilis. The <$ is quite distinct, being larger than 

 variabilis (4^-5 i- mm.). The thorax and abdomen are velvet 

 black above, the latter yellow below and at the sides. Wings
