The Plates I. to VIII. have bfcii prepared Ivom the original drawings luaile 

 by Mr. Matthews with his well-known accuracy, the tij^iues having been most 

 carefully and successfully transferred to zinc by Mr. .1. Collin, of Newmarket, 

 and I have to thank him for the trouble he has taken to make them accurate 

 copies. Mr. Matthews has unfortunately left no note of the names of the 

 species figured, and I have been unable to trace in his collection which are 

 the actual s|)eciraens from which he made his drawings. Plate A of the 

 metamorphosis has been copied from the figures accompanying M. Perris's 

 memoirs, as acknowledged. 



I have also to thank Mr. George Lewis, Mr. Champion, Mr. C. 0. Waterhouse, 

 Herr Reitter, and Signor Fiori (who acquired the Reitter collection), for assistance 

 given me: iind, ubovi all, Jlr. 0. E Janson. who has rendered most valuable 

 helj) in reading the proofs, in obtaining and verifying references to the literature, 

 and generally in getting the book through the press.
