Distribution of Lepidojptera. 421 



Arrangement and Nomenclature. 



Mr. Doubleday's Sjmonyinic List^ pviblished in 1859, 

 lias been followed, with these excejjtions : — 



1. The orthogTaphical emendations suggested in the 

 " Accentuated List/' published by the Entomological 

 Societies of Oxford and Cambridge, have been adopted. 



2. The additional species contained in the supplements 

 to Doubleday's list (1865, 1866) have been inserted, 

 and a few names altered in conformity with those sup] )le- 

 ments ; in the former case the sponsor's name has been 

 appended, and in the latter, the name used in the original 

 list put in brackets underneath the name now employed. 



3. In the genus Lithosia the species are arranged as 

 in the translation of M. Gucnee's paper on that genus, in 

 the '' The Zoologist" for I860; and the new species in 

 the g-enus Eupithecia have been most kindly inserted for 

 me in their proper places by Mr. Doubleday. 



Sotirces of Information. 



The sources from which my information has been drawn 

 are the various periodicals. Transactions of Societies, 

 and other publications (comprising nearly 200 volumes) , 

 and manuscript lists from many of the best Entomologists 

 of the day. I cannot sufficiently express my sense of 

 obligation to those gentlemen, who, often at the cost of 

 much time and labour, have given me every assistance 

 in their power, and without whose help the following 

 Tables could never have been drawn up, even in their 

 present imperfect state. 



Especially it is wished to acknowledge the kind advice 

 and information afforded by the following gentlemen : — 

 Revs. H. Harpur-Crewe, Gr. Gordon, J. Greene, E. Horton; 

 Dr. Knaggs ; Messrs. C. G. Barrett, E. Birchall (from 

 whom most of my information respecting the Lc-jjidoptcra 

 of Ireland is derived), T. Blackmore, T. Chapman, G. B. 

 Corbin, G. R. Crotch, J. C. Dale, H. Doubleday, A. 

 Edumnds, C. Feun, E. M. Geldart, G. Gascoyne, W. F. 

 Kirby, G. F. Mathew, A. G. More, R. S. Scholfield, 

 Howard Vaughan, J. Jeuner Weir, and H. C. Watson. 



The records of captures contained in the various maga- 

 zines are often very erroneous, and in the endeavour to
