ON THE TORTRICES OF CROYDON AND DISTRICT. 31 



the species maculea, fraternella, viscariella, tricolorella, costella, 

 and a continental sj)ecies hyoscyamella. This seems to me 

 another illustration of what Mr. C. A. Briggs says (Entom. xviii. 

 130), " Crammed in apparently to interpose a scientific frontier 

 between two species so often mixed." " So little known" would 

 do better in this case than " so often mixed." 



I see, as localities for knaggsiella, Dr. Wocke says — 

 " Germany ; ? Anglia." What does the " ? " mean ? Does it 

 mean that Anglia is a doubtful locality ? If so, whence were 

 the original specimens derived from which the species was 

 named ? for the same author says, " knaggsiella, St. Ann. 1866, 

 107." Were the original specimens British, as they bear 

 Mr. Stainton's name ? 



This is a puzzling group, but the different species (?) are 

 nearl}' all British ; and if notes were compared from the different 

 parts of our coast a correct result might, I think, easily be 

 obtained. 



Any information that can be given me, either by letter or in 

 the pages of the ' Entomologist ' (the latter preferred, as it might 

 help some Micro-lepidopterist), on this group, will be gratefully 

 received. Surely there must be some British entomologists who 

 can give their younger brethren some information on these, to 

 us, knotty points ; or are the older entomologists as much in the 

 dark as we are ? If so, perhaps the above is a problem worth 

 working out.

ON THE TORTRICES OF CROYDON AND DISTRICT. 



By W. G. Sheldon. 



During the past season I devoted some time to working up 

 this group ; and as Croydon is one of the most accessible 

 localities from London, a few notes from my diary may not be 

 unacceptable to some of your readers who are commencing to 

 study this interesting division. Omitting many species of 

 universal occurrence, I may mention the following : — 



Tortrix forsterana, a specimen being netted in my garden, I instituted a 

 search amongst ivy in the neighbourhood, and found the empty pupa-cases 

 tolerably common, but was too late for tenanted ones.
