84 ANNALS OF SCOTTISH NATURAL HISTORY 



brown, halteres light brown. Pilosity of thorax and abdomen 

 weaker. The species is very rare in Denmark, only one 6 

 having been taken ; and it must be rare here, as I have taken 

 it only in single examples, although in widely separated 

 localities. I found it first at Aberlady <$, 5th September 

 1903 ; then at Aberfoyle 9, 8th September 1905 ; Polton 

 c?, 1 9th September 1907 ; and Clunie, near Blairgowrie cT , 

 aist September 1910. I have also a 6 taken by Mr. Waterston 

 at Arniston, igth August 1905. 



4. EMPIS HYALIPENNIS, Fin. First recorded as British by Mr. 



Malloch who took 4 9 ? in Murroch Glen, near Bonhill, 

 25th August 1906 ("E.M.M.," 1906, p. 257). It has not 

 been recorded since ; I found a 9 at Kirkmichael (Perth- 

 shire) on 1 8th August 1910. 



5. CLINOCERA STAGNALIS, Hal. Apparently unrecorded from 



Scotland; Mr. Waterston captured a o at Prestwick, i5th 

 September 1904. 



6. SYRPHUS LAPPONICUS, Ztt. In a lot of Diptera collected by 



Mr. W. Wylie, Jun., and presented by him to the Perth Museum, 

 which Mr. Rodger sent me recently for examination, I found a 

 c of this rare species, taken at Kinnoul Hill in May 1910. 

 This makes the third recorded British specimen. Previous 

 captures are : a 9 taken at Pitlochry by Mr. Verrall in June 

 1870 ("E.M.M." 1886, p. 230), and a $ taken at Aviemore by 

 Col. Yerbury in July 1899 (" A.S.N.H.," 1900, p. 22). 

 . ONCOMYIA ATRA, F. Mr. Waterston found a $ at Whiting Bay, 

 Arran, in September 1906. The species of this genus are all 

 rare, and the only Scottish reference I can find for the present 

 one, is Duncan's old record : " neighbourhood of Edinburgh " 

 (1838), as given by Mr. Grimshaw in "A.S.N.H.," 1903, p. 218. 



8. POLIETES HIRTICRURA, Meade. Mr. Wylie captured a <$ at 



Kinfauns in August 1910, which makes the first record for 

 Perthshire. This sex has been recorded from Kilmarnock, 

 Balerno, and The Mound (Sutherlandshire). The only 9 

 known was taken by Mr. Waterston in Arran, and described by 

 him in " E.M.M. ," 1906, p. 269. 



9. PEGOMYIA TRANSVERSA, Fin. A 9 taken by Mr. Waterston in 



September 1906 in Arran. It is the finest species of the genus 

 and appears to be rare, as among many examples of British 

 Pegomyia examined I have seen it from only the New Forest 

 (F. C. Adams). I believe this to be the first Scottish record, 

 as my record of P. transversa from Aberfoyle ("E.M.M.," 

 1905, p. 163) refers to P, winthemi, Mg., = latitarsis, Ztt. 



10. PEGOMYIA ESURIENS, Mg. First recorded as British by myself 

 from Comrie ("E.M.M.," 1908, p. 128), and since taken by
