2 PORRITT : LIST OF YORKSHIRE LEPIDOPTERA. 



Generally the name of the town is given as sufficiently indicating 

 the locality of the species, but in such well-known and favourite 

 collecting grounds as Askham Bog, Edlington Wood, Bishop's 

 Wood, Thorne Waste, etc., these are given in preference for 

 such species as are known to occur there, though frequently they 

 will also be found all round the adjoining city and towns of York, 

 Doncaster, Selby, and Goole, respectively. I consider the four 

 localities just alluded to about the best in our county for general 

 collecting, we know at present. Of Askham Bog, Mr. W. Brest 

 says he " never met with a place more prolific in insect life." 

 And Mr. William Warren, of Cambridge, who collected at Don- 

 caster from 1866 to 1876, says he knows "no place so rich in 

 species, for so small a compass, as a small wood, one-and-a-half 

 miles out of the town of Doncaster." Probably in the future, 

 however, other at present comparatively unexplored spots will 

 prove to be equally productive. The most unproductive parts 

 are undoubtedly the cold, clayey districts of the South West 

 Riding, and the paucity of lepidopterous life in them is certainly 

 very discouraging to an enthusiastic student. 



Mr. N. F. Dobree's " Beverley " must often be understood 

 to include the district of Holderness generally ; while Mr. A. 

 Doncaster's " Sheffield " takes in a considerable radius round that 

 town, in order to include several favourite localities of the old 

 Sheffield collectors, some miles distant. 



For the sake of brevity I have generally given the initials of 

 the person who vouches for the locality of a species, the lepidop- 

 terists thus represented being as follows : —
