gutterjUes of Switzerland and 



the 3llp3 of Central Europe, 



BY G. WHEELER, M.A. 



Although this work is designed originally to meet the needs of collectors, it is 

 hoped that it will prove not without value to students also. Various points of 

 interest are incidentally discussed, and under the heading of the various species 

 treated, 217 in number, is given in addition to Synonyms, the difference 

 between the <? and ? ; the characters by which the Species (and generally the 

 Genus) may be distinguished from its neighbours ; the average size ; the food 

 plant of the larva, when known ; localities with dates and authorities ; the 

 approximate altitudes between which it may be found ; and the different 

 directions of Variation, with Varietal names, including many previouslyunpublished. 

 To the matter of Variation the greatest attention has been paid, and in this and 

 other points, eppecially dates and localities, much assistance has been received 

 from many of the foremost lepidopterists who reside or have travelled in 

 diflerent parts of the region. A considerable part of the information contained 

 has either not been previously published, or has only been available by 

 searching journals English. French or German. 



A list of the Localities mentioned has betu added, with some indication of 

 their geographical position, which it is hoped may prove a great saving of time 

 to non-resident collectors. • 



The book has been most carefully reduced to the smallest dimensions 

 for convenience of carriage, by the avoidance of repetition, and the use of 

 abbreviations whenever possible without obbcuring the sense. 



The published price of the book will be 5/- nett., but it will be issued at 

 4/3 post free to ail who order it before publication.
