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 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 will 

 be sent to authors for correction only when specially requested. Ed.
