AN ADDRESS TO

and the result has been, that if the collector finds that his 
insect is fig. 242 of Wood, and consequently Hadena 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 12a*. 6 d. 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.

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,
