EDITORIAL NOTICE. 
In closing the third volume of PsycHE 
with this double numero and the indexes 
which accompany it, the editors certainly owe 
an apology to the subscribers who have 
waited over two years for the completion of 
the volume. The making of the Systematic 
index could not be carried to any consider- 
able extent before the index to volume two 
was published. as the decimal classification 
of subjects in that volume was to be used as 
a basis for the classification in the present 
index. Causes similar to those which de- 
layed the issue of the index to volume two 
also prevailed to some extent in the present 
case, but it is expected that the index to vol- 
ume four will be prepared soon after the com- 
pletion of the volume. 
As was foreseen when volume three was 
begun, the form of recording then adopted 
for PsycHe has enabled the editors to fur- 
nish record of more articles in this volume 
than were recorded in volumes one and two 
combined, viz., 1854 paragraphs, whereas 
volume one contained 715 and volume two 
731 paragraphs. As in the earlier volumes, 
the index pages, though very elaborate and 
costly, are nearly all given in excess of the 
PSTCHE. 
regular number of pages due to subscribers. 
The indexes are furnished only to subscribers 
to the whole volume, or for an extra charge 
of one dollar to subscribers for less than a 
volume. 
After the issue of this numero the price of 
volume three of Psycue, either in ordinary 
form or printed on one side of the sheet, will 
be five dollars, the sanie price as is charged 
for volume four, or two copies, one in each 
form, for six dollars; and after the small 
supply of broken sets of the volume is 
exhausted, only the complete volumes will 
be obtainable from the publisher. °

PROCEEDINGS OF SOCIETIES. 
CAMBRIDGE ENTOMOLOGICAL CLUB. 
(Continued from p. 4o2.) 
12 May 1882—85th meeting. Col. T. W. 
Higginson, of Cambridge, Mass., and Mr. 
Leland O. Howard, of Washington, D. C. 
were elected active members of the Club. 
Dr. H. A. Hagen exhibited slides of the 
female genitalia in Clothilla (a psocid), and 
Prodoxus dectfiens (a tineid), showing the 
peculiar organs on the vesicula seminalis, 
whose probable function is to open the sper- 
matophores. Dr. Hagen showed plates illus- 
trating theseorgans. In Cloth/lla this organ 
is a horny plate with teeth to open sperma- 
tophores and holes at the base of the teeth 
to !et in spermatozoa. He mentioned the 
fact that, in Prodoxus, the whole length of the 
vesicula seminalis was nearly one-half that 
of the insect and nearly filled the abdomen. 
Dr. H. A. Hagen mentioned the familiar 
red-spotted appearance of the testes and sper- 
matophores in Danias archippus. 
Mr. S. H. Scudder stated that he had 
received, that day, from Mr. J. S. Kingsley, 
of Worcester, Mass., living specimens of a 
species of Scolofendrella differing from that 
mentioned by the speaker at the last meeting
