cedilis have been seen. There are very few rare beetles in the 
list, but many of our species are local. In the preface to his 
work on the Coleoptera of the British Isles, the Rev. W. W. 
Fowler remarks that there are very few common beetles, that 
is, common in the sense of being generally distributed ; al- 
though on the other hand there are very few rare ones. The 
truth of this is readily seen by an examination of our local 
beetle list and by comparing it with the lists for other 
districts. Each species has a certain habitat, and, if that 
habitat does not occur in a district, it is extremely unlikely 
that the beetle will be found there. 
We would draw special attention to the somewhat un- 
expected occurrence of Helophorus dorsalis in a pond near 
Acanthocinus edilis.

Springhead during the past few weeks. This uncommon 
species has not previously been recorded for the district, and 
is probably a relic of the former fen fauna. 
It may not be out of place to remark that a collection of 
East Riding Coleoptera is being formed in the Hull Municipal 
Museum. The late C. Russell’s collection has been bequeathed 
to the museum and this will form the nucleus of an East Riding 
collection which will be got together by Mr. W. H. Wilfred 
and the compilers of this list. Mr. Russell’s collection is 
very valuable, since it contains many species which have, as 
yet, only been taken once within the district. Any specimens 
or records will be gladly received by the curator, Mr. Shep- 
pard, at the museum, or by any of our coleopterists. 
An East Riding List is now being prepared for the next
