YORKSHIRE NATURALISTS' UXlON. It 



YORKSHIRE MICRO-LEPIDOPTERA m 1877. 



By WILLIAM PREST, York, 

 President of the Efitoniological Section. 



In recording the work done by the Micro-Lepidopterists of 

 Yorkshire during the past year, I am sorry the task has not fallen 

 into abler hands than my own. Having only a very limited 

 knowledge of the various groups of micro-lepidoptera, and only 

 the observations of myself and two or three members of the York 

 and District Field Naturalists' Society to assist me, the result 

 must be very unsatisfactory. I shall commence with the 

 Crambites, simply because I have paid more attention to that 

 group than to the Tineina proper. It being, in reports of this 

 nature, quite unnecessary to name the commonest species 

 observed, I shall only mention those that are local, moderately 

 common, or new to the county. 



Crambus Warringtonellus. I took this local species 

 quite commonly on Thorne Waste during the Union's excursion 

 there in August, and it is, I beheve, quite new to Yorkshire; 

 it has no doubt been overlooked or passed by as some common 

 species. They were in fine condition, but I should say at least 

 three weeks late. 



C. selasellus. I took two or three in Askham Bog, where 

 in fair years it is moderately common. 



C. inquinatellus. Odd specimens occurred all through 

 July and August at Sandburn and Stockton-on-the-Forest. 



Ephestla elutella. One of the most interesting features of 

 the Wetherby excursion, was the exhibition (by Mr. G. C. Dennis of 

 York) of a large sheet of web spun by the larvse of this species. 

 In August 1876 a large room in a chicory warehouse at York was 

 filled to about a foot from the ceiling, and when opened in February 

 1877, the ceiling and walls were found to be entirely covered with 

 a fine web, and the top layers of chicory were spun together in 

 galleries, and inhabited by thousands of small dirty-white larvce;
