Trichopterygide, owing to the difficulty, to any one but a specia- 
list in the group, of dealing with these highly interesting but 
almost microscopic beetles. 
The large extent of river-bank and low-lying water-meadow 
in our District is of course highly favourable to such beetles 
as delight in a humid habitat, and they are accordingly very 
well represented on the list. The extensive tracts of wood- 
land are also very productive, though some at least of these 
are so strictly preserved nowadays as to be by no means easy 
of access for collecting ; and it is especially desirable to confirm 
the numerous records of interesting species of insects of all 
orders from Bagley Wood, made when this once happy hunting- 
ground was freely open to past generations of Oxford Entomo- 
logists. The oolitic limestone country at Wytham, Shotover, 
and Elsfield yields many local species, and our “ Reserve” at 
Cothill, with the marshy fields adjacent, is a highly productive 
little spot. But on the whole, the ‘‘sandy side” of Oxford, 
at Boar's Hill and especially near Tubney, has received the 
most attention, and has produced the greatest number of rare 
and interesting forms. <A very remarkable feature of the latter 
locality is the number of species whose usual habitat is on coast 
sandhills, and which are only exceptionally met with inland ; 
of these, Harpalus anxius, Amara fulva, Homalota cesula, 
Ocypus ater, Xantholinus tricolor, Orthocerus muticus, Syncalypta 
hirsuta, Crypticus quisgutlius, Ctentopus sulphureus, Apton 
schonherri, and Cleonus sulcirostris, may be specially mentioned 
in this connexion. ‘The record by the Rev. F. W. Hope of 
“ Carabus” (Pogonus) chalceus, Marsh., is open to question, 
as this species is confined to muddy salt-marshes on the coast ; 
but Mr. Shipp has recorded Dyschirius eneus, a species fre- 
quenting the same habitat and constantly found with it, from 
“ Hinksey” (Ent. Mo. Mag. 1893, p. 89). 
In the compilation of the following List I have used our 
most recent “ Catalogue of British Coleoptera,” by Prof. T. 
Hudson Beare and Mr. H. St. J. K. Donisthorpe (London: O, E. 
Janson, March, 1904), the arrangement of which is practically 
the same as that of the most modern and most useful work 
on our native beetles, “The Coleoptera of the British Islands,” 
by the Rev. Carion W. W. Fowler (London: Lovell Reeve and 
Co.). Where the observers are not specially mentioned, I have 
used the following abbreviations of their names :-— 
IG. = Mr. Joseph Collins. 
A. H. H. = Mr. A. H. Hamm. 
W. H. = Mr. William Holland. 
TW, = Revi Be We-Hope. 
J..W.S. = Mr. J. We Shipp.
