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 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. 



SPECIAL NOTICE TO AUTHORS 



Owing to increased cost of labor and materials, only one or two plates will 

 be published in each issue of the NEWS, except where authors furnish the 

 necessary blocks or pay in advance the cost of making blocks at the rate (for 

 1917) of $2.00 per line-engraving, 6 by 4 inches, or $4.00 per half-tone, 6i by 4 

 inches. When the cost of the illustrations falls below these rates, the differ- 

 ence will be refunded to the author. Blocks furnished or paid for by authors 

 will, of course, be returned to authors after publication. 



The printer of the NEWS will furnish reprints of articles over arid above the twenty-five 

 given free at the following rates : Each printed page or fraction thereof, twenty-five copies, 

 15 cents; each half tone plate, twenty-five copies, 20 cents; each plate of line cuts, twenty- 

 five copies, 15 cents; greater numbers of copies will be at the corresponding multiples of 

 these rates.
