PREFACE. V 



sion and commission, and I shall be grateful to those who will 

 kindly point them out to me for ulterior correction. 



At the outset of my labours I had proposed that there should 

 have been a greater portion of them devoted to the descriptions 

 of the Larvse and Pupae, and with this object I sought all the 

 information I could, that bore on these points, both orally and by 

 correspondence ; and, although I found many facts were known, 

 they were scattered over the country, and in most instances unre- 

 corded, and so dependent upon memory and hearsay, that I con- 

 sidered them too crude and unauthentic to be made use of scien- 

 tifically. I preferred, therefore, to be entirely silent whenever I 

 was in doubt. The few Larvse and Pupa? which are described 

 have either been in my own possession, or the descriptions are 

 taken from recent reliable drawings. It was in consequence of 

 the vague and unsatisfactory state of our knowledge in these 

 respects, that I planned my Diary (see the 'Entomologist's 

 Weekly Intelligencer/ No. 117, p. 101), which I have found of 

 great service, and am happy to say is being adopted by others ; 

 so that, by the close of the present year, I hope to hear that 

 much recorded information on the subject has been gained, and 

 I shall be most thankful to any Entomologist who will send me 

 any communications relative to the Larvse or Pupse of the 

 Tortricina, or more particularly the Larvse or Pupse themselves. 

 This announcement I make, more especially to my Northern 

 Brethren of the Net ; and I will endeavour to make a suitable 

 return. 



One class of my readers, I expect, will feel disappointment at 

 the omission of synonymy; and a few words upon this point are 

 necessary, as I believe it is generally considered that a work 

 upon Natural History, with scientific pretensions, should not be 

 without it. As regards the Nomenclature, I have followed the 

 law of priority, by attaching to each insect the specific name 

 assigned to it by the original describer, so far as he can be 

 ascertained ; and the names I have used will, for the most part, 

 be found to correspond with the Museum Catalogue ; and I refer 

 those parties to it who may be inclined for an interesting 

 turmoil in the intricacies of synonymy, where they will find in-
