 YORKSHIRE COLEOPTERA IN 1920. 



W. J. FORDHAM, M.R.C.S., L.R.C.P., D.P.H., F.E.S. 



From the general tone of the reports on the season, it was 

 expected that the Annual Report of the Coleoptera Committee 

 for 1920 would be a very meagre one. 



However, when the final survey comes to be taken, it is 

 found that we can add eleven species, some of them very rare 

 insects, to the county list, and the following enumeration 

 of over a hundred interesting species contains many records 

 which amplify the known distribution of other beetles in the 

 county. Rather more notes than usual have appeared on 

 the order in the pages of The Naturalist and other journals, 

 and these should be consulted. Much help has been rendered 

 by various naturalists who are not Coleopterists. The 

 asterisk and dagger are used as in previous reports, and the 

 initials given are by now well known to readers of The 

 Naturalist. 



Since the Annual Meeting of the Entomological Section of 

 the Yorkshire Naturalists' Union in Leeds, the Committee 

 deplores the loss of two valuable members — H. H. Corbett 

 and J. W. Carter, as will be seen from the obituary notices in 

 The Nattiralist. 



Notiophilus substriatus Wat. Harrogate, 5/20, A. E. Winter. 



Bembidium saxaiile Gyll. Northern form. Brignall Banks, Barnard 

 Castle, M. L. T. 



B. andrecB F. v. femoraium Stm. Yore Banks, Aysgarth, G. B. Ryle 

 (*65). 



B. mannerheimi Sahl. Reeth, M. L. T. (Y. N. U., 5/20), *b^. 



B. atroviolaceiim Duf. {stomoides Dj.). Tees banks, near Yarm, 8/20, 

 M. L. T. 



Amara consiilaris Duft. Allerthorpe Common, W. J. F. 



Pterostichus csihiops Pz. Aysgarth, G. B. Ryle, *65. 



Agonum gracile Gyll. Harrogate, A. E. Winter. 



A. thoreyi Dj . Ryhill Reservoir, 5/19, W. S. F. 



Ccelambus impressopunctatus Schal. Thome, H. V. Corbett, *63. 

 ^Dytiscus circumflexus F. Saltend Common, near Hull, fairly commonly, 

 8/20, T. S., G. B. W. (see Nat., 1920, p. 407). This species had 

 not been recorded as far north previously. It is a South European 

 species, and occurs chiefly in the London district and the Fens. 



Helophorus arvernicus Muls. Brignall Banks, Banks of Greta, Barnard 

 Castle, Sept., M. L. T. 



Aleochara sparsa Heer (succicola Th.). Bubwith. in dead hen, 6/17, 

 W. J. F., *6i. 



Stichoglossa prolixa Gr. Saltburn, under bark, 1894, M. L. T., *62. 

 This insect was recorded as corticina Er. in Proc. Cleveland Field 

 Club, 1898, but has since been determined by Mr. E. A. Newbery as 

 t'he first named species (see M. L. T., Proc. Clev. N. F . Club, 1914-ig, 

 pp. 175-1S2). Mr. Thompson, in his list of additions, etc., brings 

 the Cleveland total to 1070 species. He notes that Philonthus 

 pennatis Shp. is the insect recorded from Cleveland as frossulus Nor. 

 The latter is not a common species, and most of our Yorkshire records
