statements made in their own communications. 
Works on subjects not related to entomology will not 
be reviewed in PSYCHE.

EDITORIAL. 
The undersigned, who has been hindered by 
absence from the country and by pursuit of 
other occupations from taking active part in the 
editorial management of this paper, wishes to 
record his sincerest thanks to those editors, assis- 
tant editors and other friends of PsycHr who 
have, during his absence, attended to the various 
duties connected with its publication. 
Among those to whom especial thanks are due 
is the late Edwin C. Prentiss of Brighton, Mass., 
whose death it was a painful duty to announce 
in our numero for October 1880, who, in addition 
to the composition of Psycme, making it ready 
for the press and mailing it, added often, as gra- 
tuitous labor in the interest of the paper, work 
belonging strictly to its editorial department. 
Faithful, persevering and accurate, he removed 
much of the care of Psycue from the under- 
signed, who mourns his early death, caused by 
disease contracted while in the defense of our 
country in the south, rather as that of a perso- 
nal friend than as that of an employé. 
The accuracy of Psycue, upon which we are 
often complimented, is ina great measure due 
to the careful supervision of Mr. B. P. Mann, 
who has had not only the editorship of the bib- 
liographical record, but has had most of the 
burden of the general editorship of the whole 
paper. Inassuming the management of Psycue, 
the undersigned wishes to acknowledge Mr. 
Mann’s services especially, without which it 
would have been impossible to continue the 
PSYCHE. 
paper, and to announce that hereafter the respon- 
sibility for the general management rests upon 
himself. 
During the past three years many books, pam- 
phlets and periodicals have been received as 
gifts or in exchange, and the editors will now 
strive to have these, as far as they pertain to 
entomological subjects, properly noticed in our 
bibliographical record, and, in such cases as may 
seem best, reviewed. 
The numeros of Psycue for eaeh of the years 
1880 and 1881 contained—to make a comparison 
readily perceptible to persons not familiar with 
printers’ nomenclature—exclusive of title-pages 
and advertisements, matter equivalent to more 
than 227 pages of reading matter of volume one 
or two. To this will be added, at the end of 
volume three, an index much larger than that — 
of volume one. It is unnecessary to add that 
Psycue never has paid its cost. For volume 
three it would be necessary to have a few more 
than double the present number of subscribers 
to make it pay its cost, exclusive of exchanges 
received. As the present publisher, who under- 
took the publication of Psycue in order to give 
the Cambridge Entomological Club—the foun- 
der of the magazine—time to accumulate a 
publication fund, will be obliged soon, under the 
pressure of other duties and responsibilities, to 
return the publication to the hands of its parent 
society, it is not, perhaps, improper here to 
solicit contributions to the publication fund of 
the society.
