VI INTKODtrCTION. 



work, and the names he used, also the reference to his book as 

 far as it was set up in pages. I would fain have waited for the 

 remainder, but Mr. Howse was so anxious to have the part 

 issued to the members that the last pages were printed off 

 without the number of the page in Mr. Barrett's work. These 

 are given at the end of the introduction. Having thus over- 

 taken the issue of Mr. Barrett's book, there was nothing for it 

 but to follow Stainton for the remainder of the catalogue. 

 Thus while I deplore the confusion into which the arrangement 

 of the Lepidoptera has drifted, I have blundered into confusion 

 myself, as several species included by Stainton in the groups 

 yet to follow have already been given in this catalogue. I will 

 remedy this as far as possible in the next volume by naming 

 the species in the places they appear in the '' Manual," and 

 referring to the account given of them in the present volume. 

 They are the Deltoides, the genus Nola, the Chloephoridae, and 

 Sarrothripa revayana. 



Besides Stainton's and Barrett's works, references are given 

 to Newman's "British Butterflies and Moths" — not a very 

 scifntific book, but useful to beginners on account of the 

 illustrations by which a large number of the species can be 

 recognised. After the first sheet of the catalogue was printed 

 off, a " Handbook of British Lepidoptera" by Edward Meyrick 

 was published. Keferences are given to that work except in 

 the aforesaid 16 pages. 



For figures of the larvae I have referred to the valuable work 

 of the late Wm. Buckler of Emsworth, published by the Eay 

 Society, and also to the "Food-plants of the Larvae," by the 

 late Owen Wilson. These are expensive books, not in every 

 private library, but they should be found in the reference 

 department of the Public Libraries of most large towns. There 

 are no other reliable works with coloured figures of the larvse 

 of British Lepidoptera. 



Besides the instalment of Wailes' catalogue already fully 

 referred to, the Transactions of the Society contain other 

 partial lists from the pens of the late J. Wassermann and the 

 late W. Maling. These I have incorporated in the catalogue.
