SOME NEW YORKSHIRE BEETLES. 



T. STAINFORTH, 

 Hull. 



During the past two years I have paid particular attention to 

 the Coleoptera of the East Riding shore of the Humber. Much 

 of the material collected yet awaits examination, but the follow- 

 ing notes on the occurrence of some species new to the Yorkshire 

 list which appears in the Victoria County History, may not be 

 without interest. 



Harpalus rotuxdicollis Fair. 



A single male specimen of this species was found on August 

 2gth last year, under drift at the foot of the embankment on 

 the Humber shore near Hull, between Marfieet Creek and 

 Lord's Clough. Careful examination and comparison with 

 specimens from the south of England proved it to be this species, 

 and my identification has been confirmed by Mr. E. G. Bayford, 

 of Barnsley, and Dr. W. Wallace, of Grimsby. As far as the 

 lists at my disposal show, this is the most northerly record for 

 the species, and Fowler states that he has never ' found it in 

 the north, and that it does not appear in the Yorkshire, Durham 

 and Northumberland, Scotch or Irish lists.' 



Blechri^s maurus Sturm. 



This species occurs commonly in the same locality as the 

 preceding, but it makes its habitat under the lumps of chalk 

 on the top of the embankment. They seem to affect the lumps 

 which are embedded in the clay, and on turning such a piece 

 over half-a-dozen specimens have been seen together. They 

 are so active, however, as to be difficult to catch, and if they 

 escape among the crevices between the lumps of rock, capture is 

 well nigh impossible. The species occurs less commonly in a 

 similar situation on Saltend, and I found a single specimen 

 between the grass and the stone capping of a clough on the side 

 of Hedon Haven. The dates of capture were July 28th, x\ugust 

 2oth, and October 5th, 1908. 



CCELAMBUS parallelogrammus Ahr. 



On September 20th, igo8, this little water beetle swarmed 

 in the brackish pools on the land side of the embankment 

 on the Humber shore, near the new Joint Dock at Marfieet near 

 Hull. The pools had become very low, and were swarming 

 with beetles, chiefiy consisting of this species, Agahus con- 

 spevsus, Dytiscus marginalis (some of which were dead or d3dng), 

 and Philhydrus maritimus.
