60 TRANSACTIONS OF THE 



By Mr. Peter Cameron, jun. — A collection of the social wasps 

 found within ten miles round Glasgow. They are : — Vespa vul- 

 garis, the commonest species in the district, found neai4y every- 

 where ; Vespa rufa, common at Carmyle and Possil ; V. Germanica 

 from Fossil, not so common as the previous species ; V. sylvestris, 

 a tree wasp from Milngavie, rare ; V. Norwegica from Paisley 

 Moss "Wood. The only other British wasps are V. arhorea and 

 V. Crahro. The former has been recorded from Scotland, but not 

 the latter. 



He also exhibited AUotria halterata, Thomson, the smallest 

 species of the Cynipidcb, from Kenmuir Bank ; also the dried body 

 of an Aphis, the interior of which had been devoured by an 

 AUotria, or by some species of an allied genus. 



EXCURSIONS. 



Fintry. — Mr. Richard M' Kay gave an account of this excursion. 

 He said the district between Fintry and Killearn was likely to 

 repay more searching investigation than the present excursion 

 permitted, both as regards its Fauna and Flora. Mr. Peter 

 Cameron, jun, reported finding the following Cynipidm in the 

 neighbourhood of Fintry: — Gynips lignicola, very abundant in all 

 the woods ; Dryophanta divisa, Dryophanta fecundatrix, Dryoteras 

 terminate, Neuroterus numismatis, N. lenticularis, Rhodites rosce, 

 all common ; Andricus noduli, apparently rare. He also found a 

 small Aphilothrix which is apparently new to the British list, as 

 it cannot be satisfactorily identified with any of those already 

 described. 



Fossil Marsh. — Mr. Alex. Watt gave an account of this excur- 

 sion. Many of the more frequent species of the aquatic fauna were 

 collected, including Goleoptera and Hemiptera of several species, also 

 the lai-vse of several species of Goleoptera, Neuropiera, Trichoptera, 

 and Diptera, among which was the very interesting larva of a 

 small gnat, Gorethra plumicornis, often termed the glass cr phantom 

 larva, on account of its extreme transparency, which permits of a 

 clear view of the internal organs and their action. Amongst the 

 Mollusca Lymncea stagnalis was found. This species was intro- 

 duced into the marsh some years ago. Numbers of empty shells 

 of Dreissena polymorpha were noticed amongst the mud and debris 

 thrown out of the adjoining canal.
