PREFACE. 



Though several books have appeared on the Macrolepidoptera of Europe, 

 a new work with good ilkistrations and of reasonable price ma}' still be useful. It is to 

 fill this want that the Authors have decided upon placing the present volume before 

 their readers. 



Space has not pemiitted them to include all the European species, but most 

 of those inhabiting Central Europe have been dealt with, and nearly all those of 

 the British Isles will be found described or figured. All the British species have 

 English names assigned to them, a feature which has been neglected in many books 

 of recent date. 



The average expanse of the wings, in inches, will be found after the names 

 in the Index of Latin Names, so that, if the reader wishes to know the size of a 

 species, he can at once ascertain it by referring to that Index. Necessary intomiation 

 respecting structure, collecting, etc., will be found in the Introduction. 



THE AUTHORS.
