[The Conductors of ENTOMOLOGICAL NEWS solicit and will thankfully receive items 

 of news likely to interest its readers from any source. The author's name will be given

To Contributors. All contributions will be considered and passed upon at out 

 earliest convenience, and, as far as may be, will be published according to date of recep- 

 tion. ENTOMOLOGICAL NEWS has reached a circulation, both in numbers and circumfer- 

 ence, as to make it necessary to put " copy " into the hands of the printer, for each num- 

 ber, three 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., MARCH, 1908. 



At the present time it is possible to have made excellent il- 

 lustrations of insects by the half-tone process or by line en- 

 graving, provided the copy or drawings are good and properly 

 prepared. For many purposes a line cut is just as good as a 

 half-tone and costs very much less. We frequently have sent 

 to us copy for plates that is troublesome or not suitable, be- 

 cause some authors do not know anything about the methods 

 of reproduction of plate copy. Copy for line engraving should 

 consist of lines and dots only and the ink used should be the 

 blackest the artist can procure. If a number of small drawings 

 are made for line engraving, make them so that they can be 

 assembled into a single plate, or draw them all on one card. If 

 blocked separately, it adds enormously to the cost. The half- 

 tone is used for wash drawings and the reproduction of photo- 

 graphs. Always remember that everything shows in a half- 

 tone and that the outlines of many figures are such that the 

 plate cannot be tooled, or routed, or outlined. We get copy 

 consisting of line and dot work and wash drawing and photo- 

 graphs mixed and this necessitates making a half-tone, where- 

 as, if kept separate, both processes could be used separately at 

 less expense. If you make small sketches on separate cards, 

 bear in mind that if assembled, the reduction must be the same 

 for all of them, therefore make them with this in view. It is 

 always a good plan to have the drawings or photographs larger 



than the size of the resulting plate.
