are mentioned as having occurred in the vicinity of that town. 

 The former of these two lists, it is almost unnecessary to ob- 

 serve, dates at a period when descriptive Entomology was in its 

 infancy, but the remarks of the reverend author, some of which 

 I shall quote, show that he was a close and generally accurate 

 observer of nature. Of the latter it is sufficient to state that 

 Entomology formed a very subordinate portion of the labours of 

 the learned author. Passing over the scattered notices of 

 northern habitats communicated by others and myself to Mr. 

 Stephens and Mr. Curtis, and incorporated in their celebrated 

 works on British Entomology, or supplied to other general pub- 

 lications on the science, the next list forms a striking contrast to 

 the former meagre catalogue of our local Lepidoptera — I aUude to 

 that contained in Mr. Selby's well known "Fauna of Twizell,*' 

 as given in the 3rd vol. of the "Annals of Natural History," for 

 the year 1839, wherein he enumerates upAvards of 370 species 

 of this order, as being found there, and to which a few subse- 

 quent captures are added by him in the Proceedings of the Ber- 

 wickshire Naturalists' Club. These will all be mentioned in 

 their proper places as I proceed, and I would only remark, that 

 embowered in his fine woods, in a favourable locality, with a true 

 love for nature, and ample leisure to pursue the study, together 

 with the adoption of a mode of capture just then coming into use 

 and peculiarly fitted for such a place as Twizell, it is not sur- 

 prising that his list is so extensive. The only other local cata- 

 logue remaining to be noticed is the " List of some of the 

 Insects found in the County," appended to the Rev. George 

 Ornsby's " Sketches of Durham," published in 1846, and 

 including 144 species of Lepidoptera, which will be duly referred 

 to. Not having had any opportunity of personally examining 

 the specimens from which the two last- mentioned lists have been 

 framed, I cannot vouch for the correctness of the nomenclature, 

 especially amongst the smaller or more obscure species, but as 

 both Wallis and Mr. Hogg have given their authorities, I am 

 enabled, in some measure, to identify the insects they have 

 indicated. 



The completion of the Catalogue appears to me to be the
