NOTE LEPIDOPTERA. 



variety of Dyschirtus polities occurs rarely, and a good Bledius, 

 which appears to be crassicollis, but concerning the identity of which 

 there appears to be some doubt, may be taken in any quantity, if its 

 casts on the clay cliffs are discovered. It must be either erraticus or 

 crassicollis (these being the only two in the group of Bledius to which 

 it belongs), if it is not a new species to Britain ; it certainly is not 

 the former, and in some points differs from Dr. Power's specimens of 

 the latter, but I believe that they are really identical. Dyschirius 

 thoracicus, accompanied by Bledius arenarius and Stenus melauopus, 

 occurs in great numbers, and Stenus guttula is also very plentiful. 

 I have taken one specimen of Amara consularis in a sandy place 

 near the town. Several Bembidia (saxatile, tibiale, affine, &c.) are not 

 uncommon, and in damp places some little way up the cliffs I have 

 found Georyssus pygmceus, looking like little animated balls of mud. 

 I have no doubt that many others might be found, but as I was 

 searching for two or three species particularly, I only observed those 

 that came in my way. 



The grassy sides of the cliffs near Filey are exceedingly produc- 

 tive. I never found beetles more plentifully by swe'eping than on 

 one occasion on a strip of grass on the top of the cliff, at the edge of 

 a cornfield not far from the town ; the best beetle I took near Filey 

 was Cassida hemisphcerica (the only other specimen I have ever seen 

 alive was one that I found last summer at Tenby) ; but some very 

 good Hemiptera, notably the very rare Derceocoris seticornis, well 

 repaid me for my trouble. — 



LEPIDOPTERA. 



Oncocera ahenella and Oatoptria expallidana in York- 

 shire. — The claim of Oncocera ahenella to be regarded as a Yorkshire insect 

 rests on the recorded occurrence of the species at Huddersfield. In the 'Yorkshire 

 List of Lepidoptera,' p. ill, I expressed the opinion that the specimen had 

 somehow got there accidentally, but I am now compelled to believe otherwise. 

 And, indeed, on the first appearance of the Yorkshire List, Mr. Peter Inchbald, 

 F.L.S. (who formerly resided at Huddersfield), wrote me I might rest perfectly- 

 satisfied as to the capture and the correct determination of the species at the time. 

 I have now further and very strong confirmation that such was the case, as will be 

 felt from what follows : — Recently I purchased the cabinet and collection of 

 lepidoptera formed by the late Mr. George Liversedge, who was for so many 

 years treasurer to the Huddersfield Naturalists' Society. Mr. Liversedge professed 

 no knowledge of the smaller species of lepidoptera, and had not in any way attempted 

 to arrange or even name them. But for some years, as I well knew at the time, he 

 collected a good many micro-lepidoptera ; which he set and put away in some of 

 the unarranged drawers of the cabinet. Scattered among these, in different 

 drawers, I found five specimens of Oncocera ahenella, all evidently set in the 

 same manner, and by the same person, as the many surrounding well-known 

 Huddersfield micros. As Mr. Liversedge collected a great deal in the vicinity, 

 and probably on the same ground the original specimen or specimens were 

 supposed to have been taken, there can, I think, now be no reasonable doubt that he 

 actually took them there. Among the micros, too, I picked -out a single specimen 

 of Catoptria expallidana, the only previous record for Yorkshire being the one 

 taken by myself in my own garden, but near which Sonchus arve?isis grew freely 

 (See 'Yorkshire List,' p. 129). — Geo. T. Porritt, Huddersfield, Jan. 2 7th, 1886.
