12 AN ADDRESS TO 



was an u unknown tongue " to the inhabitant of another), 

 and the result has been, that if the collector finds that his 

 insect is fig. 242 of Wood, and consequently Haclena och- 

 racea, he has then to find by what name Hadena ochracea 

 of Wood is now known ; for which purpose he must refer to 

 the index of Stephens's Museum Catalogue of British Lepi- 

 doptera. It was to supply this difficulty, a great and in- 

 creasing one, that a new edition of Wood's Index Entomo- 

 logicus has lately been brought out at a considerable reduc- 

 tion of price, and with the nomenclature carefully revised ; 

 but the figures are not as well coloured as the original edi- 

 tion, and those who can meet with the original at book stalls 

 will do well to secure the prize. 



Humphrey's and Westwood's British Butterflies and 

 British Moths is a work which, from being showy and cheap, 

 is tolerably well dispersed amongst Entomologists, but the 

 figures are far inferior to those in Wood, and it will rarely 

 enable a collector to name any but his most conspicuous 

 species. It is true some species are figured in it, not known 

 as British at the time of the publication of Wood, but these 

 have been included in a supplement to Wood's Index Ento- 

 mologicus, published last year, and which for the small price 

 of 12s. 6d. contains 180 figures. 



Lately there has appeared a revised and much improved 

 edition of Humphrey's and Westwood's British Butterflies, 

 the plates to which are entirely new, and only those species 

 are in it admitted as British which are adopted as such by 

 Stephens in his Museum Catalogue of British Lepidoptera. 

 The title of this last and best work on our butterflies is 

 " The Butterflies of Great Britain ; with their Transforma- 

 tions, delineated and described by J. O. Westwood." 



But even the fortunate possessor of several works on 

 Entomology will still find himself at a loss to name many 

 of his specimens; yet there are several Entomologists, who,
