In order to facilitate a return to the former practise of publishing Psyche 
on the first day of the month of publication, the June and August numbers have 
been combined in this double number, appearing August i. Henceforth it will 
be the aim of the Publication Committee to adhere to the old rule. 
Correspondents are asked to take notice that henceforth all material for 
publication in a given number must be in the hands of the Editors on or before 
the first day of the month preceding the month of publication. 
Entomologem Addressbuch. — By W. Junk, Rathenower Strasse 22, Berlin. 
N. \V., Germany. 
Considering the field covered by this work, viz: — the names and addresses 
of the leading entomologists throughout the world, it is certainly very creditable 
to the author, and the most complete Directory along these lines which has been 
published. Not only are the names arranged under countries, but also alphabet- 
ically, which adds to its value and convenience. There are over 400 pages, 114 
of which are devoted to a catalogue of numerous new and second-hand books, for 
sale by the author. H. H. N. 
The address of Mrs. A. T. Slosson will hereafter be 83 Irving Place, New 
York City, instead of 38 East 23 Street, as formerly.
