Vol. XXV ] ENTOMOLOGICAL NEWS. 325 



A Jubilee. 



We extend to our fellow journal, The Entomologist's Monthly 

 Magazine, our heartiest congratulations upon the fiftieth anniversary 

 of its existence, June I, 1914, and wish it continued success. 



The Magazine was founded by E. C. Rye, H. T. Stainton, R. Mc- 

 Lachlan, Dr. H. G. Knaggs and T. Blackburn. As one after another 

 of these withdrew or deceased, their places were filled by others. 

 McLachlan was the last survivor of the original board of editors and 

 maintained his connection with the journal until his death on May 

 23, 1904- 



The June, 1914, number contains an interesting sketch of the 

 Magazine's history, with eight portraits of its founders and early 

 editors. 



Colias eurytheme Boisd. and its varieties (Lepid.). 



The fixation of a type and the accurate illustration of types will 

 make a considerable difference in our nomenclature and the standing 

 of many species and varieties. Eurytheme has been placed as a variety 

 of chrysotheme Esper and probably correctly so. Dr. Verity in his 

 "Rhopalocera Palaearctica" has figured Boisduval's types (now in the 

 Oberthiir collection) of eurytheme Bd. and amphidusa Bd. Keewaydin 

 Edw. is a synonym of eurytheme, and ariadne Edw. is a synonym of 

 amphidusa. Strecker, in his Catalogue of American Macrolepidop- 

 tera, page 83, describes ab. $ flava, destitute of every trace of orange. 

 Dr. Verity (p. 273, pi. 49, fig. 41) describes '$ ab. flavesccns. If 

 eurytheme is considered a variety of chrysotheme this would make 

 fiavescens a synonym of flava. 



Californiana Menetries is doubtless a synonym of eurytheme or 

 amphidusa. Eriphyle Edw. is a yellow form of which hagcni Edw. is 

 a synonym. Intermedia Ckll. and autumnalis Ckll. come in somewhere 

 between the other names. How many names we shall have is largely 

 a matter of opinion. The relationship of so-called species of Colias 

 is not well understood. Even philodice and eurytheme may be forms 

 of one species. In the mountains of North Carolina, they can only 

 be told apart by the color, being either yellow or orange respectively.

Suggestions for the Bibliographical Dictionary of Entomologists. 



Apropos of the editorial in the May NEWS: For Deppe localities 

 see Ann. Mag. Nat. Hist., September, 1910, p. 284. At the New York 

 Botanical Garden they have a system of large envelopes open at the 

 top, in which they put all sorts of data relating to botanists. Each 

 botanist has his envelope. Would not this be a good plan for ento- 

 mologists? In this way much good material will accumulate for the 

 future historian or biographer. The Philadelphia Academy would
