THE BRITISH NATURALIST. 



[May 



I should be particularly glad of records of this species from Northern 

 Counties. Observers should be careful not to confound this with the 

 growth known as "fingers-and-toes," nor with the attack of the fungus, 

 Pewnospom bmssicce. * 



Hymenoptera, 66 sp. Chiefly belonging to the Cynipidce, and mostly 

 attached to oak, on which there are about 40 species in Britain. 

 Figures and descriptions of all the European species will be found 

 in the "Entomologist," 1874 to 1875. The other gall-making 

 Hymenoptera are Sawflies attached to willow, for which see 

 Cameron's " Phytophagous Hymenoptera " (Ray Soc.) ; and 

 several species attached to rose, the best known being the mossy 

 gall, bedeguar. 



Diptera, 91 sp. Chiefly of the genera Cecidomyia and Trypata. A list 

 of the British Cecidomyidse, by Mr. Fitch, will be found " Ento- 

 mologist," XIII, 146, and of Trypata 11 Entomologist," X., 31 ; 

 XII., 257 and 259 ; XV., 138 ; also various papers by Inchbald. 



Lepidoptera, 3 sp. Asychna avatella, Lavema decorella, and Retinia 

 resinana. 



Homoptera, 8 sp. Belonging to Aphidina. Fully described in Buck- 

 tons " British Aphides " (Ray Soc). 



Arachnidlae, 13 sp. Produced by the leaf mites (Phytoptus), 

 enumerated, along with several European species in Murray's 

 " Aptera " (S. Kensington Handbook).

Leioptilus osteodactyhis, Zell. — This brightly tinted species feeds on 

 the same plants and is found in almost the same localities as tephm- 

 dactyla. It is also very local in Britain although abundant where it 

 occurs.

Imago — The fore-wings of this species are divided into two lobes 

 and they are of a clear pale yellow or sulphur colour, with a slightly 

 darker costa. Just beyond the disc is a short black longitudinal 

 patch. The hind-wings are divided into three plumules and are of a 

 greyer tint than the fore- wings. Stainton's diagnosis is as follows : — 

 " Fore-wings very pale sulphur, with a brown dot before the fissure,
