3a THE SCOTTISH NATURALIST 



most interesting of the many records are perhaps those of Helix 

 nemoralis from St Cyrus, which further defines the northern Hmit 

 of the species in Britain, and of Mi/ax sowerbyi from Argyll, the 

 most northerly record along the western side of Scotland. 



Parasitic Beetles in Scottish Homoptera. Mr F. Muir 

 records that amongst Delphacidse collected by him in Scotland by 

 sweeping over a small patch of grass, about thirty per cent, bore 

 Stylops parasites {E7it. Mo. Mag., vol. 54, 1918, p. 137). 



Ant-dwelling Moth {Myrmecozella) at Rannoch. In a 

 short account of that curious guest of the ants Myrmecozella 

 ochraceella Rev. J. W. Metcalfe describes the large numbers of 

 Ant-dwelling Moths in all stages of freshness found in a particular 

 ants' nest near Rannoch. The ant turned out to be a distinct 

 variety Formica nifa var. alpina ; and the abundance of the moth 

 in this nest, contrasted with its scarcity in true rufa nests in the 

 district, leads the author to speculate that the rare variety may be 

 preferred as a host by the Ant-dwelling Moth {E?itom., October 

 1918, p. 222). 



BOOK NOTICE. 



An Ornithologist's Field Note Book. By Hugh S. Gladstone. 

 London: Bickers i!^ Son, Ltd., 1918. Price 2d. 



Under the above title Captain Gladstone has prepared and published 

 a very neat little list (4I x 3 ins.) of the British birds which are either 

 breeding species in or regular visitors to our islands. Its main object 

 is to furnish, in a convenient form, a note book in which to enter for 

 future use, or for pleasure, the various birds observed on a visit to a new 

 locality or during a country walk. The list is printed in single column 

 and on one side of the paper only, in order to afford space for the 

 addition of any of the rare species, or for further information relating to 

 the others. It has also an educational value to beginners, since the 

 faunal status of each species is indicated. The nomenclature is that of 

 the British Ornithologists' Union's List. The list fulfils its object, and 

 supplies what has long been a want.
