EAST RIDING COLEOPTERA IN 1906. 

 By T. Stainkorth. 



THE past year has been somewhat productive of good 

 results. At least six new records can be placed on our 

 lists, and the known localities for many previously 

 recorded species have also been increased. It is all the more 

 pleasing that this work has been done for the most part on 

 the society's official excursions, many of which the recorder 

 has been able to attend. 



From a coleopterist's point of view, the most successful 

 excursion held was at Flamborough, under the auspices 

 of the Yorkshire Naturalists' Union. Inclusive of all the 

 commoner beetles, between 100 to 120 species were here 

 obtained, the more obscure of which have not yet been 

 identified. The most interesting species found were Dys- 

 chirius thoracicus, Rossi. ; Amara fulva, Dej., Aleochara 

 nitida* Grav. ; Cafius xantholoma, Grav. (extremely common 

 in rotting seaweed) ; Epurcea cestiva* L. ; Rhagonycha lim- 

 bata /* and Ceuthorrynchus assi?nilis ;* and in addition to 

 these, a list sent by Mr. M. L. Thompson, supplies Tropi- 

 phorus tomeiifosits. 



On the Figham Common excursion, on June 9th, Mr. 

 H. C. Drake obtained from the Barmston drain a specimen 

 of Brychius elevatus, a species for the occurrence of which 

 we had previously been content with an unconfirmed though 

 trustworthy record. On the excursion to Driffield the 

 following week, the recorder obtained another specimen 

 from the river Hull, together with Platambus maculatus 

 (previously recorded for Sutton drain only) in abundance. 

 The banks of Sutton drain supplied a new record in Bem- 

 bidium flamvmlatum* which occurred on the mud in some 

 numbers. On the Skipwith Common excursion, on Sep- 

 tember 1st, were obtained Bembidhim lunatwn and Tachypus 

 flavipes (on the banks of the Ouse), Notiopliilus palustris, 

 and the larva of the Tiger Beetle, Cicindela campeslris. 

 Numerous borings from which larvae were obtained, proved 

 the occurrence of this beetle, which does not appear to have 

 been previously recorded for this locality, although its pre- 

 sence there has doubtless been known. Mr. W. Ward 

 informs me that his father used to obtain the Tiger Beetle 

 on the sandy tract at Snake Hall near North Cave.
