g PREFACE. 



The descriptions of species and varieties in this edition 

 that were not in former editions are to be found at the 

 close of the volume, each numbered so that its place in 

 the general arrangement can be readily found. In the 

 body of the book where these would occur they are re- 

 ferred to by a " See Addenda." As, for instance, on 

 page 119, Callidryas Statira is thus referred to, and on 

 page 389 this species will be found with a number 17|, 

 thus indicating that it should stand between Nos. 17 

 and 18.
