PREFACE. Vn 



Coleophora bicolorella, 



Laverna raschkiella, 



Laverna phrag^mitella, 



Elachista pallidum, 



Lithocolletis cavella, 



Lithocolletis sorbi, 



Lithocolletis cerasicolella, 



Lithocolletis torminella, 



Bucculatrix frang-ulella. 



Nepticula serella, 



Pterophorus punctidactykis, 



Pterophorus paludum. 

 Of these fifty-three the great majority, as might be expected, 

 belong to the Micro-lepidoptera ; only eleven belong to the 

 "macros," and of them, seven at least, S. pinastri^ E. autumn- 

 ai'ia, B. fuliginaria, F. pinetaria^ X. sollikoferi, L. exigiui^ 

 and E. fuscula, cannot be regarded as anything more than 

 "casuals." Of the "micros," the discovery of several not 

 only added them to the Yorkshire, but to the British List ; 

 one of them, indeed, G. tetragonella^ was new to science, and 

 another, N. serella, was practically so. 



Against the new additions, there were ten species in- 

 cluded in the original list, which on further investigation 

 and experience, I am now convinced ought never to have 

 been included, as follows : — 



Acidalia interjectaria, 



Nonagria cannae, 



Cledeobia angustalis, 



Stenia punctalis, 



Phycis ornatella, 

 Ebulea verbascalis, 



Orthotasnia antiquana, 

 Retinia resinana, 



Conchylis gigantana, 

 Pterophorus phaeodactylus.
