A most conscientious and valuable contribution to the literature of 
economic Entomology. After some introductory observations, (1) a 
Catalogue is given of former publications on the subject, with full 
bibliographical references, and distinction of papers containing mention 
of the larval anatomy and metamorphosis ; followed by (2) a full scien- 
tific Catalogue of the genera and described species (arranged alphabeti- 
cally), also with bibliographical references, and accompanied by syno- 
nymical and other notes, especially a«i to the habits of the larvse, where 
known. Of these, 463 are recognized, including 5 described but not 
named. (3) These species, 143 in number, of which the economy and 
larva are known, but not the perfect insects, are in like manner discussed ; 
and the work concludes with (4) a botanical alphabetical index of the 
plants attacked.
