NOTES on YORKSHIRE LEPIDOPTERA . 



Proposed Supplement to the ' List of Yorkshire Lepidoptera.'— 



During the past few years the desirability of publishing- a Supplement to 

 the 'List of Yorkshire Lepidoptera' has been suggested to me over and 

 over again, and as lately the appeal has been made oftener and more 

 forcibly, I have decided, if I can secure the necessary co-operation of 

 Yorkshire lepidopterists, to compile such supplement. I am probably in 

 possession of all, or nearly all, of the published information since the issue 

 of the original list in 1883, but a number of our lepidopterists must be in 

 possession of much useful information which has not been published, and it 

 is to them I now appeal. I want particularly full details of the captures of 

 any species, should there be such, which are not included in the county 

 list, and have not been recorded since 1883. Also lists of fresh localities 

 .for all local species, especially from districts which, up to 1883, had been 

 little, or not at all, worked. Lastly, I shall be glad of particulars as to 

 local variation of all species, even including the commonest. 



All information should be forwarded to me as soon as possible. — Geo. T. 

 Porritt, Crosland Hall, near Huddersfield, 4th January 1902. 



Hermaphroditism in Crocallis elinguaria. —I possess two herma- 

 phrodite specimens of the Scalloped Oak Moth {Crocallis elinguaria) bred 

 in 1899, from eggs obtained from Everingham in 1898. One has the left 

 antenna male and the rig'ht female, and the other has the right antenna male 

 and the left female. Both specimens are in beautiful condition. — William 

 Hewett, York, 18th January 1902. 



Eupithecia isogrammata at Doncaster : an Addition to the 

 Yorkshire County List. — Mr. L. S. Brady, of Sheffield, informs me that 

 he found larvae of Eupithecia isugrammata in the greatest profusion in 

 flower buds of Clematis vitalba growing at Wadworth, near Doncaster, in 

 August last. The species has not previously been recorded for Yorkshire, 

 and is a very interesting addition. — Geo. T. Porritt, Crosland Hall, near 

 Huddersfield, 4th January 1902. 



Since the foregoing was written, I have had an opportunity of looking- 

 throug-h the manuscript of Mr. John Sumner's list of the Lepidoptera of 

 Everingham, and find the species is included there. As it is several years 

 since the list was compiled, the credit of adding the insect to the Yorkshire 

 List is due to Mr. Sumner. — Geo. T. Porritt, 21st January 1902, 



Lepidoptera Captured near Middlesbrough in 1901. The following 

 are a few of the more noteworthy Lepidoptera that 1 have come across 

 during the past season in the Middlesbrough district : — 



Acronycta megacephala. A single specimen, 5th June, on Poplar tree 

 trunk in Cambridge Road, Middlesbrough. 



Calamia lutosa. A specimen taken off grass stem in garden, Linthorpe, 

 Middlesbrough, on 14th September. 



Mamestra albicolon. A single worn specimen at sugar in garden, 

 Linthorpe, Middlesbroug-h, on 24th June. Another specimen 'poked' out 

 of sand-banks at Redcar, on 4th July. The latter specimen was a $ , 

 and laid a quantity of ova about the 8th ; these hatched out in due course, 

 but I was unsuccessful in rearing- them, the larvae rotting- off in the early 

 stages in a way peculiar to a good many Noctua larvae. I notice there is 

 only one locality recorded for this insect in Mr. Porritt's Yorkshire list, but 

 I have no doubt it would be taken all along the ^ coast if sugared for at the 

 proper time. 



Pachnobia leucographa. Took three specimens, all 9 s, off Sallows in 

 April, at Saltburn-by-the-Sea. I also took three specimens, all $ s, in the 

 same locality in 1900. 



Tceniocampa populeti. Two worn specimens, taken off Sallows in April, 

 at Kildale. — T. Ashton Lofthouse, The Croft, Linthorpe, Middlesbrough, 

 December 1901.
