X PREFACE. 



1869 ; ' Entomologist's Monthly Magazine/ vol. vi, 

 p. 232." 



Those descriptions which had not been previously 

 published bear only the references to Mr. Buckler's 

 Note-Books, of which he left four volumes. 



To supply the gaps in the present volume, owing to 

 the omission of Mr. Buckler to prepare descriptions of 

 many of the larvae which he had figured, recourse has 

 been had to the kind services of his former coadjutor, 

 the Rev. John Hellins, who, while the printing of the 

 earlier portion of the volume was in progress, was most 

 assiduous in collecting from many of his friends a 

 mass of material which appears in the Appendix (see 

 pp. 145—198). 



In spite, however, of all that Mr. Hellins and his 

 numerous correspondents could do, descriptions of a 

 few larvae (Aporia Cratcegi, Melitcea Cinxia, Thecla 

 pruni and T. W- Album) are still wanting, though we 

 give figures of them. 



I am well aware that with Mr. Hellins his work in the 

 Appendix has been a labour of love, but none the less 

 do I feel how very, very much we are indebted to him for 

 his valuable aid. 



Till after Mr. Buckler's death I was not at all 

 aware that he had ever contemplated the publication 

 of his numerous drawings (altogether he must have 

 executed more than six thousand drawings of larvae 

 and pupae), but it seems from some written instructions 

 that he certainly had had such a desire, and the wish, 

 both of Mr. Hellins and myself, has been to render this 

 posthumous work a worthy memento of one whom we 

 loved and esteemed in his lifetime. It is in contempla- 

 tion to issue, as soon as possible, a second volume
