one another that it is desirable to discuss them separately ; but 

 before doing so a little time may be devoted to a brief notice of 

 the more important articles that deal with these insects and their 

 galls in Scotland. They are as follows : Mr. James Hardy writes 



On the Effects produced by some Insects, &c, upon 



Plants, in the Annals and Magazine of Natural History, 1850, 

 VI., pp. 182-188, and in the Transactions of the Botanical Society 

 of Edinburgh, IV., p. 79. Mr. Hardy also published a paper in 

 1854, in the Scottish Gardener ; but I have not been able to get a 

 sight of this volume, so cannot speak with certainty of what the 

 paper contains. However, all Mr. Hardy's papers include gall- 

 midges among the gall-makers commented on. 



Mr. Albert Mueller published an article on British Gall- 

 insects, in the Entomologist's Animal for 1872, in which he 

 enumerated several galls from Scotland, sent to him by me from 

 near Aberdeen. One of these he had already recorded, (Proc. 

 Ent. Soc. Lond., 1871, p. 8), viz. that formed by the midge named 

 by him (provisionally from the gall) 0. Campanuhe, from the 

 bluebell. Prof. J. W. H. Trail, in 1870, began to study the galls 

 of the counties near Aberdeen ; and (in absence of any compre- 

 hensive records of the galls of Scotland) in 187 1 to publish a 

 series of articles entitled Scottish Galls, a series which, with 

 a good many breaks, has run through the volumes of the "Scottish 

 Naturalist " since vol. I. These articles are to be found at the 

 following pages: vol. I. (1871-72), 123-25, 156-59, 195-96, 

 234-35; vol. II. (1873-74), 30-32, 78-80, 172-73, 252-54,301-4; 

 vol. IV. (1877-78), 14-15, 168-70; vol. V. (1879-80), 213-16; 

 vol. VI. (1881-82), 15-20, 255-57; N. Series, vol. 1.(1883-84), 

 206-216, 276-80; vol. II. (1886), pp. 250, 302; vol. III. (1887), 

 pp. 107-110. 



Mr. Francis Binnie published a paper On Dipterous Gall- 

 makers and their Galls in the Transactions of the Glasgow 

 Field Naturalists' Society, 1876, part IV. pp. 154-64; and other 

 papers in the Proceedings of the Nat. History Society of Glasgow, 



1877, IV. part, On the Asphondylise of the Glasgow- 

 District, pp. in-114; Notes on Cecidomyia Trifolii F. 

 Low, and its Gall, p. 114; and Further Notes on 

 the Cecidomyidse, with Descriptions of three New 



Species, pp. 178-185. In all his papers Mr. Binnie records the 

 Gall-midges of the district around Glasgow.
