MORE RECORDS OF YORKSHIRE COLEOPTERA. 
GEO. B. WALSH, B.Sc. 
( Scarborough ). 
Our knowledge of the Coleoptera has advanced so much 
of recent years that it becomes necessary drastically to revise 
many of the Yorkshire records. In many cases, especially 
where it has been shown that a reputed species consists in 
reality of two species or of a congerie of species, it will 
certainly be wisest to scrap all existing fecords and start 
anew ; as examples we may quote the species associated 
with Haliplus ruficollis, Nebria brevicollis , Atheta melanocera, 
the genus Gabrius, and the like. It probably sounds severe, 
but, in the same way, all old records of unusual species should 
be held suspect until such time as they have been confirmed 
by recent workers ; in many cases this will undoubtedly be 
done, as, for example, with many of Bissill’s old records ; 
on the other hand, other records — for example, some of 
Lawson’s Scarborough records of wood-feeding beetles, which 
were almost certainly based on specimens introduced with 
foreign timber — will inevitably finally be deleted. It would 
seem wise, also, to put on permanent record the occurrence 
of common insects in localities rarely visited, so that in the 
finish we may have a more or less complete knowledge of our 
fauna available for ecological or zoogeographical study. 
Finally, all specimens of which there is the least doubt should 
be submitted to some authority on that particular group for 
confirmation or otherwise. 
It is in the spirit of these remarks that the following notes 
are made. All specimens of importance have been con- 
firmed by Dr. Malcolm Cameron or Mr. J. H. Keys, 
according to the group, and Dr. W. J. Fordham has 
assisted with the Yorkshire distribution. The order and 
nomenclature are in accordance with Beare’s List of 1930. 
The past two years, 1931 and 1932, have been particularly 
inimical to insect life. Though the rainfall for the years is 
probably not far removed from the normal, yet most of it 
has fallen in the summer months, and heavy floods in May, 
June and September, have occurred just at the time when 
they are likely to do the most harm. Large quantities of 
flood refuse were collected at Yedingham on two occasions, 
as the following records show, but general collecting has 
proved of little avail. Nevertheless, a few unusual insects 
have turned up and these are recorded below. 
Nebria brevicollis Fabr. (s. str.) Under stones at Hunmanby, and on 
the cliffs at Bridlington. 
N. iberica Oliv. Under fallen trees in Beedale.
