DIPTERA NEW TO THE SCOTTISH LIST 263 



17. Homalomyia umbrosa. Stein. — Blairgowrie, (^ , 3rd June 191 1. 



A distinct species, not known to Malloch when he drew 

 up his paper on the genus published in Scot. Naf., 1912. 



18. Sciomyza diibia, Fin. — Polton, ^, 6th August 1906; Mussel- 



burgh, 2 $ $ , 26th June 1907. These agree with the 

 description in Hendel's "Revision"' (1902). The species 

 was added to the British List by Meade {E?ii. Mo. Mag., 

 1899, p. 102), but it had previously been recorded by 

 Verrall {Enfom., 1891, p. 236). 



19. Tetanura pallidiventris, Fin. — Polton, 2 ? ?, 9th September 



1906; Blairgowrie, (^ , 23rd June 1908,9, 6th June 19 11. 



20. Psila pallida. Fin. — Aberlady, $, 7th June 1904. An entirely 



pale yellow species, which is certainly the one described 

 by Schiner under this name. 



21. Sapromyza decipiens, Lw. — Callander, (^ , 9th September 1904. 



Becker (1895) gives this as a synonym of sordida, Hal, 



but they are distinct. I have seen specimens of the latter 

 from England. 



22. Sapromyza difformis, Lw. — Blairgowrie, ?, 12th June 1913. 



I have also a 9 from Bonhill (Malloch). This is rather like 

 the common rorida, Fin., but has only one sterno-pleural 

 bristle, and the acrostichal bristles are distinctly bi-serial. 



23. Piophila nigrkornis, Mg. — Blairgowrie, cj , 25th May 1908. 



Cryphalus abietis Ratzb. in Peeblesshire. — On 24th 

 August I found considerable numbers of C. abietis on young silver 

 firs on Early vale Estate near Eddleston. Some account of its 

 occurrence may be of interest. The wood in which I found it is of 

 considerable extent and consists of spruce and Scots pine with here 

 and there isolated groups of silver fir which have apparently been 

 introduced as underwood. The majority of these firs were in 

 a sickly condition and on these Cryphalus was found. Scarcely 

 a stem was free of it. It attacks the tree at each whorl of branches 

 where tiny heaps of "bore meal" indicate its presence. Cryphalus 

 abietis is probably widely distributed in Scotland, its apparent rarity 

 being due to the comparative scarcity of its host plant which has 

 recently been entirely given up as a forest tree. The majority of 

 our silver firs are now old trees whose branches are well above 

 ground and out of reach for the average collector. — James VV.
