FIRST SUPPLEMENT 
TO THE 
PRELIMINARY LIST OF THE COLEOPTERA 
OF THE OXFORD DISTRICT, 
Published in the Report of the Ashmolean Natural 
History Society of Oxfordshire for 1906. 
By JAMES J. WALKER, Hon M.A,, R.N., F.L.S. 
THE past year of grace 1907, although it left so much 
to be desired from a meteorological point of view, has proved 
to be by no means one of the worst for Insects in general, 
and for Coleoptera in particular. This is evident from the fact 
that in the following Supplement I am able to add the very 
satisfactory number of 183 species to the list of this Order 
of Insects occurring within a radius of about seven miles from 
the City of Oxford, which was published in our Report for last 
year. It is true that a considerable number of these additions 
are species of wide distribution and common occurrence in the 
British Isles, which might reasonably be expected to occur in our 
District, but of which we had no definite record when the first 
list was compiled; but among the remainder are very many 
forms of great interest, and of more or less local distribution, and 
several which rank at present among the greatest of our rarities. 
Besides these additions to our List, new localities have been 
found for a large number of our less common beetles, and many 
rare and local species have been taken, some of which are re- 
corded in the volume of the ‘‘ Entomologist’s Monthly Maga- 
zine” for last year. My colleagues in the Hope Department of 
the Oxford University Museum, Messrs. Holland, Hamm, and 
Collins, have contributed a large number of the additional species, 
which, as before, are indicated by their respective initials. Mr. 
Collins especially has devoted a great deal of time and attention 
to the Staphylinide, and especially to the interesting little group 
of species, mostly belonging to that family, which are associated 
with the Wood Ant, ormica rufa. The result of his industry
