their late editions, are incontestable proofs of the 
high degrees of estimation they entertained of it.” 
The work, which embodied many of the rarities of 
this collection,* derived its principal value from the

the reader in observing the figures ; but the locali- 
ties are indicated with some care, and the trivial 
names of Linnarus to a certain extent applied, being 
the first attempt of the kind made in this country. 
The original deficiencies of the text, however, are 
now amply made up, and a high degree of value 
imparted to the work, even iu the present state of 
the science, in a beautiful edition published three 
years ago under the editorial superintendence of 
Mr. Westwood, who has added much additional 
matter, and given, wherever practicable, an account 
of the different states of the species, in which the 
original work was wholly defective, not a single 
lepidopterous larva being either figured or described. 
This work, therefore, has on two separate occasions 
been of important service to the history of the noc-
