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 our 

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

 tion. Ento.mological 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., June, 1900. 



The collecting season is now well inaugurated and a few 

 words on the proper methods of work may not be amiss. In- 

 stead of collecting for the pleasure of seeing your captures 

 neatly arranged in rows in the cabinet, take up some problem 

 in entomology and .study it to a conclusion. There are many of 

 our common species about which we know nothing of their 

 earlier stages, and those persons living in the country could do 

 excellent scientific work by studying and describing them. If 

 each person would take up a season's work of this kind the 

 aggregate at the end of the Summer months would be surprising. 

 The study of sea.sonal variation is also most interesting, and to 

 do this intelligently all .specimens should have accurate data on 

 the pins. Another field of work is the study of geographical 

 variation ; therefore collect large .series and exchange with 

 your friends and correspondents. Even common .species may 

 be forced to tell interesting stories in this respect. For in- 

 stance, is not the Colias philodice of the East the same as the 

 sulphur butterfly of the West, which goes under another name ? 

 Let each entomologi.st this vSummer take up a season's work 

 and publish the result in the News. 



Correction,— In the News for May, 1900, page 455, under E. Calverti, 

 third long primer line, read " bright blue /cmalcs,^^ instead of " males.'^ 

 Page 458, under S. madidum add "a single teneral male."
