TO CONTRIBUTORS. All 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. 



PHILADELPHIA, PA., FEBRUARY, 1911. 



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. MICHELSON, 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. 

 TTis 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.
