 PLANT GALLS OF THE HUDDERSFIELD DISTRICT. 



WM. FALCONER, 



Slaithwaite, Huddet^fitld. 



The following is a list of all the plant galls which have been 

 found to occur, up to the present, in the Huddersfield drainage 

 area — the basins of the Colne, Holme and Fenay Beck. Most 

 of them have been collected since May 1917, but many were 

 already known from the same localities to Mr. S. L. Mosley. 

 Additional records were also obtained verbally from him 

 or extracted from his little work ' British Galls," reprinted 

 from The Naturalists' Journal in 1903, all distinguished by his 

 initials. The journeys to Armitage Bridge and Ellen Springs 

 were undertaken in company with him and Mr. B. Langrick, 

 and those to lower Butternab Wood, Sun Dean and Lepton 

 with him and two ladies. 68 kinds of galls are recorded, but 

 their full distribution in the district still requires working out. 



HYMENOPTERA. 



Pontania proxima Lepel. Long leaved willows, Ellen Springs, Slaith- 

 waite, Linthwaite ; abundant and probably in other localities. 



Biorhiza pallida Oliv. Holme Moss plantation, S.L.M. ; Butternab 

 Wood, on a tree near the kennels ; Whitley Woods. 



B. aptera Bosc. Oak roots, Lepton Great Wood. 



Andricus pilosus Adlr., form fecundator. Holme Moss plantation, 

 S.L.M. ; Ellen Springs, Butternab Wood, several places about Slaithwaite, 

 Drop Clough (Marsden), abundant. In Butternab Wood, several galls 

 were still ' cone-like,' and the internal woody gall of one cut through 

 still contained the larva in February ; also in Drop Clough on March 2nd, 

 but the inner gall was empty ; MoUicar Woods, Lepton Great Wood, 

 Whitley Woods. 



A. inflator Htg. Drop Clough, Lepton Great Wood. 



A. autumnalis Htg. MoUicar Woods. 



A. trilineatus Htg., form radicis Fabr. Butternab Wood and Lepton 

 Great Wood, S.L.M. 



Neuroierns baccarum Linn. Hagg Wood, Honley, S.L.M. ; Bottoms 

 Wood, Slaithwaite, known for 13 years. 



N. baccarum Linn, form lenticularis Oliv. Bottoms Wood, Slaithwaite, 

 known for 18 years. 



Dryaphanta tischenbergi Schl. form folii Linn. Holme Moss plantation, 

 S.L.M. ; Ellen Springs, Butternab Wood, Ainley Place, Holmfirth. Mr. 

 I. Oldroyd of Scholes, an ardent fisherman, collects these galls, and fishes 

 with the flies which breed out of them, finding them more ' killing ' than 

 any other he has used for the purpose. 



Trigonaspis megaptera Panz. Huddersfield, S.L.M. 



Cynips knllari Htg. MoUicar Woods, S.L.M., great tits were busily 

 engaged in digging the galls open to devour the contained larvae, fully 

 three-quarters being so treated ; Bottoms Wood, Slaithwaite, known for 18 

 years. 



Andricus solitarius Fonsc. Lepton and Shrogg Lane, Kirkheaton, 

 S.L.M. ; lower Butternab Wood, Drop Clough, Cockatoo Wood, Honley. 



Andricus ostreus Gir. Butternab Wood, two examples. 



Andricus lucidus Htg. Whitley Woods, Huddersfield, S.L.M. 



Dryophanta, disticha Htg. Lower Butternab Wood, fairly numerous. 

 Connold states 'nowhere common.'
