PREFACE. IX 



restrict the letterpress of this volume to the materials 

 left by Mr. Buckler and Mr. Hellins, without further 

 seeking for any extraneous aid. 



As in the previous volumes, the letters W. B. or J. H. 

 after each description indicate whether written by 

 William Buckler or by John Hellins, and the figures 

 immediately following give the date when the descrip- 

 tion was written for publication, the reference that 

 follows being to the volume and page of the ' Ento- 

 mologist's Monthly Magazine,' or to Mr. Buckler's 

 Note Books. 



"We are again indebted to Mr. G. 0. Bignell for a 

 list of the parasites bred from the larvae of which the 

 present volume treats.
