FORTY-SIXTH ANNUAL REPORT, FOR I907. 
27 
The Hymenoptera and the Diptera have been hsted in the 
Victoria History of Yorkshire," in which 578 species of the 
former group and 368 of the latter group are enumerated, forming 
the starting-point for future investigation. 
Unfortunately the Hemiptera were not included, and to 
supply this deficiency, Mr. W. Denison Roebuck has collected 
the records and prepared a list for future publication in the 
Transactions. Taking the group in the very broad acceptation 
of the later modern text-books of zoology, the list includes records 
of 54 Hemiptera-Heteroptera, 27 Cicadina, 7 Psyllina, 6 Aphidina, 
9 Coccidina, 12 Anoplura, and 133 Mallophaga, which have been 
either certainly or presumably found in Yorkshire, making a 
complete total of 257 species. 
The Committee trust to receive the co-operation of all into 
whose hands specimens of these orders may come, and was 
appointed as follows : — 
Chairman — G. T. Porritt, Huddersfield. 
Convener — W. Denison Roebuck, Leeds. 
Referees — Percy H. Grimshaw, for Diptera; Edward Saunders, 
Claude Morley, Rev. F. D. Morice, M.A., for Hymen- 
optera. 
Other Members — ^Edwin G. Bayford, Barnsley ; Rev. W. C. Hey, 
West Ay ton ; M. Lawson Thompson, Saltburn ; J. 
W. Carter, Bradford ; H. H. Corbett, Doncaster ; 
T. Stainforth, Hull ; and H. C. Drake, Hull. 
Soppitt Memorial Library. — This library has been freely 
consulted during the year, and thirty-four books have been issued 
to members. The following have been added to the collection, 
Ecology of Woodland Plants in the Neighbourhood of Hudders- 
field," by T. W. Woodhead, and " Butomus umbellatus," by 
Vv^oodhead and Kirchner. 
The Committee consists of Messrs. C. Crossland, G. T. 
Porritt, and W. West (Trustees), with Dr. T. W. Woodhead 
as Librarian. 
British Association.— The British Association this year 
was held at Leicester, and the Hon. Sec, Mr. Sheppard, repre- 
sented the Union at the conference of delegates from scientific 
sooieties which was there held. Amongst the matters discussed 
by the delegates were : the Question of Local Geography, Botanical 
Survey, etc. ; the Preservation of Ancient Monuments ; the Study 
of Fungi, etc. In most of the work suggested, however, it was 
found that the Yorkshire Naturalists' Union was already taking a 
prominent part ; and with regard to the study of fungi, our society 
was congratulated on being the first to have produced a county 
fungus flora. 
Mr. Sheppard has been appointed delegate for the Union for 
the 1908 meeting at Dublin.
