ENTOMOLOGICAL NEWS. 



[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 

 in each case, for the information of cataloguers and bibliographers.] 



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., February, 1905. 



If in the evolution of species there had been no breaks or gaps 

 it would be impossible to differentiate species, and even now 

 complete series would make it very difficult to draw lines and 

 separations. Our tools, so to speak, for the identification of 

 species may be divided into figures, word descriptions and 

 types. Some very distinguished entomologists believed in the 

 former two tools only, as they did not care to go beyond the 

 failure or the possibilities of the tools. A carpenter may say 

 feet and inches are fine but millimeters are of doubtful value 

 and micromillimeters perfectly idiotic. We can sympathize 

 with that carpenter as micromillimeters are of no value to him. 

 Figures and more particularly words may appear equally 

 idiotic to some entomologi.sts because they are inadequate to 

 describe or differentiate some of the minute differences in in- 

 sects. In other words, in .some instances the study has gone 

 beyond the standards of measurement. When we are stranded 

 in this way recourse must be had to types, and that is why 

 types are becoming more and more worshipped every day. 

 Would it not be infinitely better to wait until the tools or 

 standards of measurement become delicate enough to measure 

 all differences and not let the mihi itch run away with our 

 sound judgment ? 



To make the thing clearer and perhaps to illustrate and ex- 

 aggerate a tendency we cite the following : The celebrated 

 maramologist, Dr. Coyote, discovers a peculiar beetle among
