TWO ADDITIONS TO THE BEITISH LIST OF DIPTERA. 

 BY A. E. J. CARTER. 



1. Amalopis schineri, Kol. 



As far back as September, 1904, while collecting Biptera at Cal- 

 lander, Perthshire, I took a <$ of this species. It has stood in my 

 collection since as doubtful littoralis, and while going critically over 

 the genus recently, I noticed that it could not be that insect. Like 

 littoralis (Mg.), schineri is a yellow species, but is not quite so large, 

 and the wings are clear, not yellow-tinted ; the veins are dark, only 

 the costa, Sc, and E.1 being yellow. The whole of the head and 

 antenna? are light yellow. There is no trace of a dorsal stripe on the 

 abdomen, which is all light yellow, becoming darker at the apex. The 

 hypopygium, too, is quite different, the forceps bearing at the apex 

 numerous small black spines. 



Dr. Grriinberg (Siisswasserfauna Deutschlands, 1910) says that 

 schineri is probably identical with geniculata (Mg.). Now the late 

 Mr. Verrall, in his " List of Brit. Tipulidse, &c." (published in this 

 Magazine, 1886-88), gives geniculata as a "Reputed British species," 

 with a reference to Stephens' Syst. Cat., ii, 245, and says that " the 

 specimen in the British Museum is a small, true, Amalopis.'''' Mr. F. W. 

 Edwards has very kindly looked up the old Collections of British 

 Diptera, but is unable to trace Stephens' specimen, so that its identi- 

 fication still remains uncertain. The two species, from the descrip- 

 tions, are certainly very closely allied, and I am sorry I have no speci- 

 men of geniculata to enable. me to compare the hypopygia. 



I have a $ specimen taken at Aberfoyle on September 11th, 1905, 

 which agrees in all respects with the <$ from Callander, but there is 

 no discal cell in either wing. Herr Lunclstrom, in his " Dipt. Fin- 

 lands " (1907) records a <$ and $ of schineri, and says that the discal 

 cell is present in the ? , but not in the £ ! In my specimens, too, the 

 radial cross- vein is absent in both wings of the $ , and present in the 

 right wing only of the <$ . 



2. Argyra auricollis, Mg. 



In the April number of this Magazine for,1905 (p. 83), the late 

 Mr. Verrall, writing of the genus Argyra, said, " three or four more 

 species ought to occur in Britain." Only one species has been added 

 since, viz., grata, Lw. {cf. Ent. Mo. Mag., 1912, p. 57). I am glad 

 now to be able to add another. My specimens — four £ $ , and
