PREFACE. 
IV. — Concerning the tigures, I can only say that every effort has been 
made to secure accuracy in representing the various species. The process 
of chromo-lithography was chosen as being most likely to attain this end ; 
and Mr. Knight, the artist, whose name appears on each plate, has drawn 
the figures under my direction, in most cases from Nature, only two or three 
having been copied from authentic figures. The majority of the European 
butterflies have not before been figured in any English work ; and one or 
two are, I believe, represented here altogether for the first time. Only two 
species — one, Lyccena Panope, a very rare Russian species, and the second 
a newly-discovered member of the family Hesperidse — are unavoidably 
omitted. 
V. — The figures of larvae and pupae are mostly taken from Hfibner, some 
few from Millim’e, it being impossible to obtain living specimens from 
which to draw them. These plates are merely intended to include typical 
examples of the different genera ; and in most cases those species are given 
which do not occur in Britain, and with which British collectors are least 
likely to be already familiar. 
VI. — In conclusion, I have great pleasure in alluding to the kind 
consideration and courtesy I have everywhere received from all those who 
have in any way assisted me in the production of this volume. To the 
following, especially, I wish to record my thanks : — The President and 
Council of the Entomological Society of London, for the unusual facilities 
given ine in the unrestricted use of the Society’s library ; the official staff 
of the Zoological Department of the British Museum in charge of the 
entomological collections, especially Messrs. A. G. Butler, F.L.S., and 
W. F. Kirby, for their kind assistance and interest ; Messrs. F. Ducane 
Godman, F.R.S., and 0. Salvin, F.R.S., for their kindness in so readily 
allowing me to make use of their magnificent collection, and for the 
loan of specimens whenever I required them for figures or descriptions. 
Lastly, I thank all those gentlemen who have helped me with their valuable 
advice or suggestions, and I know that they will believe me when I say 
that I have done my best to follow them whenever practicable. Though 
I may not have always been successful in carrying out the wishes of 
correspondents, and though there are in this book many things which I, 
the author, would gladly see l)etter accomplished, yet I know that those 
who read it will be the first to recognise the difficulty of the undertaking ; 
and so, I may venture to hope, will look more at the useful side of the book 
than at its failings.
