TO CONTRIBUTORS.—AIl contributions will be considered and passed 
upon at our earliest convenience, and, as far as may be, will be published 
according to date of reception. _ENTOMOLOGICAL NEWS has reached 
a circulation, both in numbers and circumference, as to make it neces- 
sary to put ‘“‘copy’’ into the hands of the printer, for each number, four 
weeks before date of issue. This should be remembered in sending special 
or important matter for a certain issue. Twenty-five ‘‘extras,’’ without 
change in form, will be given free, when they are wanted: and this 
should be so stated on the MS., along with the number desired. The 
receipt of all papers will be acknowledged.—Ed.

The versatility of insects is well shown by the inducements 
which they hold out to man to serve as the objects of his most 
varied study. From papers and references in this number of 
the NEws we find them continually increasing his catalogues 
of animal forms, exercising his ingenuity to escape their un- 
welcome personal attentions to his body, serving as the mate- 
rial for experiments on the method and manner of inheritance 
or for the examination of minute details of the structure of 
the living cell, illustrating complicated problems of physics, 
disturbing his ideas of the operations of climatic influences 
upon life. All these branches of human intellectual activity 
are of the larger Entomology wherein each of us who reads 
these lines tries to do his part. 
Dr. A. A. MicHeEtson, of the University of Chicago, delivered the 
seventh lecture upon the J. C. Campbell Foundation of the Sigma Xi 
Society of the Ohio State University on the evening of December 2. 
His subject was “Metallic Colors in Birds and Insects.” The lecture 
was amply illustrated by lantern and reflectoscope and was concluded 
by an explanation of the most probable cause as found by the lecturer 
as a result of his researches——Science, Dec. 23, 1910.
