natural history students are those who will find it of the most real 
use. e are sincerely thankful to the publishers for the present 
attractive edition of this lately unattainable work; though we 
cannot approve of their economy in suppressing a part of the 
plates, and cannot but regret that they did not induce the author 
to give us a book written in the spirit of 1871, instead of repub- 
lishing the ideas of 1850.— R. H. W. 
REVISION OF SOME OF THE AMERICAN BUTTERFLIES.* —In ad- 
vance of the publication of the volume on the Butterflies of New 
England, upon which Mr. Scudder has been for some time en- 
gaged, and which is not far from completion, the public is pre- 
sented with this digest of the results reached by the author ina 
revised classification and nomenclature of the butterflies of the 
New England and Middle States. 
The four years of almost continuous labor which the author has 
devoted to the preparation of the volume above referred to, —the 
abundant material which the kindness of friends has placed at his 
disposal, the favorable opportunity enjoyed by him during å 
two years’ sojourn in Europe for the study of large numbers of 
European forms in connexion with our own, and a persistent 
` determination to investigate personally, so far as possible, a 
of the four stages of every species reviewed by him, — lead us cf 
indulge the hope that the scheme submitted in the above pap 
may be received by both American and European lepidopterists %5 
more satisfactory than any which has preceded it. It is presen me 
at the present time, to afford opportunity for examination 
criticism, and for the correction in the forthcoming volume of ra 
errors which may be discovered. 
Although it has long been evident that many chan 3 
essarily be made in the classification and nomenclature of o 
diurnals, yet those introduced in this paper are so mane A 
some of so radical a nature, that the entomological public Ue ay 
startled at their presentation, and prompted to look for some 
of escape from their unpalatable acceptance. gii
