Kirby and Spencc (Intro.- i. 192) state that this species is 

 injurious to rose trees, but on what evidence I do not know. 

 The perfect insects are sometimes beaten out of rose bushes, 

 but I do not see what injury they can do to them. Probably 

 Hylotoma ?vsce, Fab., the larvae of which feed on roses, is 

 meant. 



DIPTERA AT BRAEMAR, ABERDEEN, AND ABERLADY, 

 INCLUDING SIX SPECIES NOT HITHERTO RECORDED AS 



BRITISH. 

 By G. H. VERRALL, Sec. Ext. Soc. 



HAVING an opportunity of obtaining a short holiday last July, I left 

 London on the night of Thursday, the 17th, in company with Mr. 

 J. H. A. Jenner, of Lewes, with the intention of having a few days' collect- 

 ing in Scotland. After a rather tedious journey, nearly all of which was in 

 beautiful weather, we arrived at Aberdeen about two o'clock on Friday 

 afternoon, to find that there it was raining, and had rained so much that 

 we expected to catch but little that afternoon. However, after finding out 

 Mr. W. A. Vice, who had kindly offered us his hospitalities during our 

 stay at Aberdeen, and having washed and fed, we found the weather so 

 much improved, that we, and Mr. Traill, ventured to Scotston Moor, and 

 I, at least, was amply repaid, as I captured one species of the Dolichopodid^ 

 new to Britain, which seems to be Sympycnus nigritibialis of Zetterstedt 

 (Dipt. Scan xii. 4638), described by him in 1855 as Dolichopiis nigritibialis, 

 from a single male caught by Holmgrem in 1852 in CEland. It has never 

 since been recorded, and has not even been ranged under its proper genus, 

 though Zetterstedt called especial attention to its close alliance with his 

 D. brevicornis ( — Sympycnus czneicoxa Mg). I expect it occurred in some 

 abundance, though I only caught three pairs, as I did not distinguish it at 

 the time from the common 6*. annulipes. New to me also were Syntormon 

 tarsatus (abundant), Tachytrechus notatus (one male), and Hilara matrona 

 (abundant) ; while of other species I noticed Dolichopiis atripes, signatus 

 and nubilus, Syntormon pumilus, Campsicnemus scambus and curvipes, 

 Gymnoplemns citprens, Ardoptera irroi ata, near the extreme corner towards 

 Aberdeen, a Hilara, which I cannot name (though also caught at Rannoch 

 in 1870), hovering over the stream near the same corner ; it is a greyish 

 species, rather large, and the female has the hind tibiae flattened and bent ; 

 Clinocera stagnalis, Elgiva albiseta, Limnia lineata, Tetanocera elata ? and 

 in great abundance on a wall a Spilogaster (? consimilis P'all). The only 

 Syrphida: I saw were Chrysogastet metallina (abundant), and Ascia floralis 

 (rare). 



The evening was spent looking over Mr. Vice's collection, in which were
