PREFACE. IX 



Unfortunately, of many comparatively common 

 species, which had long ago been carefully figured both 

 in the larva and pupa state by William Buckler, no 

 descriptive notes had been published by him, nor were 

 any found amongst his papers ; it was necessary, 

 therefore, to try and supply to some extent these 

 omissions. 



From the year 1858 down to his death in January, 

 1884, William Buckler had been in constant correspond- 

 ence with the Eev. John Hellins, M. A., of Exeter ; they 

 studied the larvae separately, but compared their notes, 

 and before any of Buckler's descriptions appeared in 

 print the manuscript was sent to Mr. Hellins for care- 

 ful and conscientious revision. The two thus worked 

 together more than is ordinarily the case ; of many 

 larvee Hellins wrote the descriptions and sent them 

 to Buckler for his critical scrutiny, and they were then 

 published under the name of John Hellins. 



Hence in the body of this volume the authorship of 

 the descriptions which had been already published 

 pertains sometimes to Buckler and sometimes to 

 Hellins. 



The letters W. B. or J. H. after each description 

 indicate the name of the writer; the figures imme- 

 diately following give the date when the description 

 was written for publication, and the reference that 

 follows is to the volume and page of the 6 Entomologist's 

 Monthly Magazine ;' thus at page 8, we see " W. B., 28, 

 2, 82; E.M.M. XVIII, 244;" which stands for "Wil- 

 liam Buckler, 28th February, 1882 ; ' Entomologist's 

 Monthly Magazine,' vol. xviii, page 244 ;" and at page 

 19 we see "J. H., 14, 12, 69; E.M.M. VI, 232;" 

 which stands for " John Hellins, 14th December,
