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 necessary to put 

 "copy" for each number into the hands of the printer five 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 and without 

 covers, will be given free, when they are wanted ; if more than twenty-five 

 copies are desired, this should be stated on the MS. The receipt of all papers 

 will be acknowledged. Proof vvill be sent to authors for correction only when 

 specially requested. _

 lished in the NEWS during 1919, except where authors furnish the necessary

 application to the Editor. Blocks furnished or paid for by authors will, of 

 course, be returned to authors, after publication, if desired.
