 degree. 



As in the previous volume 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 ' Entomo- 

 logists' Monthly Magazine ' or to Mr. Buckler's Note 

 Books. 



To Mr. G. C. Bignell we are again indebted for a list 

 of the parasites bred from the larvas, of which the 

 present volume treats.
