INTRODUCTION. Xxix 



The classifications of Boisduval and Duponchel ran on 

 similar lines, except that they paid more attention to larval 

 characters ; largely increased the number of families and sub- 

 families ; and transferred the Platyptericidce to the Bombyces. 



After the middle of the nineteenth century, however, the 

 Linnean system, which had practically survived almost unaltered, 

 began to be undermined. The arrangement of moths adopted 

 by Herrich-Schiiffer in his " Aussereuropiiische Schmettcr- 

 linge" (1850-58), is as follows, as far as they were included in 

 his book : — ■
