NOTES 29 



Skipper or Saury in the Outer Hebrides. In September 

 last, while riding across the ford which separates the island of 

 Vallay from the main island of North Uist, I saw a fish stranded 

 in some shallow water. I took it at first for a large Sand-eel, but 

 it proved to be a specimen of Scombresox saurus, the Skipper or 

 Saury. It was 13 inches in length, and had a bill 1.25 inches 

 long. I have never seen this fish here before. George Beveridge, 

 Vallay, North Uist. 



[This fish appears, as far as we have been able to ascertain, to be 

 new to the fauna of the Outer Hebrides. It has no place in the 

 late Dr Harvie-Brown's list of the " Fishes of the West of Scotland" 

 published in the Fauna of the Outer Hebrides. During rough 

 weather numbers are sometimes cast ashore in the Firth of Forth, 

 and this was the case in the late autumn of 1919, but it appears 

 to come little under notice at other times. Eds.] 



Diptera ne"w to the Scottish List. The following Diptera, 

 so far as I know, have not yet been recorded from Scotland : 



Medeferus jaculus, Mg. Occurs in my garden here on walls and 

 tree-trunks. First noticed in July 19 18 in some numbers and both 

 sexes. It is recorded by Verrall from Penzance to Porthcawl 

 (Glamorgan). 



Eumerus sfrigatus, Fin. In my garden, 28th May 19 19, a fine 



$, but no more seen. Verrall's most northerly record is from 



Norfolk. The larva has been found in, and the flies bred from, the 



common onion. This is the first species of the genus to be recorded 



from Scotland. 



Hyetodesia vagaus, Fin. A ^ of this fine species was taken at 

 Blairgowrie (Perthshire) on 23rd July 19 10. It is not much known 

 as a British species, and appears to be recorded from Warwickshire 

 only. 



Borborus nofabilis, Coll. This is an interesting capture, as since 

 the species was described by Mr J. E. Collin in E?it. Alon. Mag., 

 1902, p. 55, from a single $ taken in Suffolk, I have seen no further 

 record. A cj taken in my garden on 30th June 1918 agrees with 

 the description, but the size is just 4 mm. instead of 4^ mm. 



Helomyza affi?iis, Mg. Three ? $ taken at Blairgowrie, 5th 

 June 1908, 25th May 1911, and ist June 1913 respectively, agree 

 with the description in Loew's Europaischen Helomyzidae (1859), 

 and with specimens from England I have seen named by Mr 

 Collin. A. E. J. Carter, Monifieth.
