YORKSHIRE NATURALISTS' UNION. 
"'Miscellaneous Volume, part 2. Towards this we have 
in hand MSS. of an appendix to the Flora of Dewsbury ; the 
list of Fung-i taken at Maltby ; the Geological Bibliographies 
for 1 902- 1 905, and a list of the members, and also the reprints 
of the Excursion Programmes for 1905, which are already 
printed off, and this report. 
SECTIONS. 
The President and Secretary of the Union are ex-ofiicio Members 
of all the Sections and Committees. 
Vertebrate Section. — Mr. R. Fortune writes :— There is 
nothing very special to report. The meetings have not been well 
attended, and we hope that during the 1906 season, all the members 
of this section will do their best to attend the excursions. 
''Birds of Yorkshire." — Mr. Nelson has now^ completed his 
labors in connection with this work, and satisfactory arrangements 
having been made for publishing the book, the work is being 
proceeded with. 
The following were elected for 1906 : — 
President — T. H. Nelson, Redcar. 
Secretaries— H. B. Booth, Bradford ; R. Fortune, Harrogate ; 
A. White, Leeds. 
Representative on Executive — R. Fortune. 
Representative on Committee of Suggestions— A. White. 
Entomological Section, 1905.— Mr. William Hewett 
and Mr. Arthur Whittaker report that the season on the whole 
may be considered as having been a satisfactory one from an 
Entomological standpoint. Two new species, Acidalia emutaria 
and Euchromia mygindana^ ha\ e been added to the county list. 
Good w^ork has been done in many districts, and very many 
interesting and local species have been obtained, whilst it is 
evident that "Melanism" is still on the increase, the latest 
species to show this phase of development being Agrotis agathina 
from near Penistone, obtained by Mr. Morley of Skelmanthorpe. 
The causes of the relative abundance or scarcity of different 
species from year to year, and the gradual extension or diminu- 
tion of their areas of distribution are alike interesting subjects 
for the consideration of, and if possible, solution by all enthusi- 
astic and intelligent Entomologists. Details of the various 
captures, &c., will appear in the " Naturalist " shortly.
