PREFACE. 



The subject of the .'3rd volume of the Catalogue of Leindopiera 

 PJialcence is the last of the three subfamilies of the Arctiadce — the 

 Arctiance, in which 946 species are described and classified ; the 

 Volume also contains the small family Agaristidce, with 225 species, 

 a somewhat specialized development from the Noctuidce, the antennge 

 being modified in relation to their day-flying habits. 



Since the death of Dr. Staudinger his collection has not been 

 available for study, and it has not been possible to examine a few 

 of the Pala3arctic and Neotropical types of Ai'dianw which he had 

 kindly promised to send to London, as he had so liberally done on 

 former occasions ; nearly the whole of them had, however, already 

 been examined and, as will be seen by the list on pp. 513, 514, but 

 few remain the classification of which is uncertain. 



I have again to thank all those who had assisted Sir George 

 Hampson in the preparation of the former volumes, for their help 

 with this one ; also M. Ch. Oberthiir of Rennes, Herr G. Weymer 

 of Elberfeld, and Dr. Carlos Berg of Buenos Ayres, for the loan of 

 types described by them.
