NOTES ON COLEOPTERA OF THE 
FAMILY STAPHYLINIDAE IN N.E. YORKSHIRE. 
M. LAWSON THOMPSON, 
Saltburn-by-the-Sea. 
SINcE the publication of that portion of the List of the Coleoptera 
of Yorkshire relating to the Staphylinide, I have been able to 
add a number of species to those there mentioned, and new 
localities for some of the insects for which the records were 
found to be deficient. 
These beetles are here given an account of in the form of 
short notes respecting their occurrence in the county, as far as 
my experience yet goes. I have marked with an asterisk the 
49 species which do not find a place in the published list at all; 
whilst with regard to the remainder, the new locality or localities 
will serve in each case to supplement the single record already 
existing. 
My only reason for the insertion in these notes of so many 
common insects is that the county list is still in process of 
formation, and not only of publication. Many of the Staphy- 
linide are difficult to determine satisfactorily, and it is with 
gratitude that I acknowledge having received much valuable 
assistance from Messrs. W. G. Blatch and E. A. Newbery in 
this respect. 
*Aleochara succicola Thoms. Common on the coast at Salt- 
burn, in dead birds. Mr. Champion has pointed out 
(‘Entomologists’ Monthly Magazine,’ May 1897) that the 
insects standing as the common mes¢a Grav. in British 
collections must be referred to this species, the true masta 
Grav. being a much rarer insect. 
*Aleochara grisea Kr. Among sea-weed and shingle on the 
coast ; Saltburn, common; shore of the Tees, near Redcar. 
*Aleochara obscurella Er. Common on the coast at Saltburn. 
Aleochara algarum Fauv. Saltburn, on the coast. 
Oxypoda sae Grav. In decaying sea-weed on the coast at 
Saltbur 
Oxypoda prsuee Grav. Saltburn, in autumn; Arncliffe 
ood, Glaisdale. 
*Oxypoda longiuscula Er. Saltburn. 
Ocalea castanea Er. Saltburn, at roots of grass on the sea- 
banks. — 
May 1898.
