0, LEPIDOPTERA (Butterflies and Moths). 



The district from the Ravensbourne to the Darenth, here sur- 

 veyed, has been the hunting-ground of our leading lepidopterists 

 for over two centuries Ray, Banks, Stephens, Curtis, Stainton, 

 Darwin, Douglas. Weir, MacLachlan, Scott, and many others 

 lived and worked here, and had it not been for the somewhat 

 limited time in which the list has had to be . compiled, 

 a remarkable one could have been presented. The "old 

 days," however, of the district are past ; the extension 

 of ' 'London " into the old suburban districts, the further extension 

 of suburban London, the filling up and destruction of "Greenwich 

 Marshes," and, not least, the increase of the ubiquitous sparrow, have 

 all tended to reduce the haunts of many of our local species, and, 

 in many places, to exterminate some of the more local and rare 

 ones altogether. When once one gets outside London, the district is 

 still a very rich one in the matter of species, even if some are no 

 longer as abundant as formerly. The exclusion of West Wickham 

 and Darenth has necessitated many omissions of species that 

 possibly exist within our limits, but have not been captured there, 

 collectors going to these famous central localities, where a "bag" 

 is almost a matter of certainty. It will be noted here and there 

 that these localities are mentioned when the records have been taken 

 from local lists including these places within their boundaries. 

 There have been many helpers in the production of this list, and 

 the following lepidopterists, most of whom have sent records, appear 

 by their initials :
