RECENT LITERATURE. 



A Revision of Some Species of Euchloe. 



A Preliminary Account of the Leindopterous Fauna of Guelt-es-Stel, 

 Central Algeria. By "Walter Rothschild, Ph.D., F.R.S. 



In the ' Novitates Zoologicae ' (vol. xxi. pp. 299-357), October, 

 1914, there is an extremely interesting paper summing up the results 

 of Lord Rothschild's investigation of the Central Algerian Lepido- 

 ptera. To collectors of palaBarctic insects, however, it has a wider 

 interest than faunistic, for incidentally the author clears up a number 

 of obscure points in the nomenclature of the genus Euchloe, and for 

 the first time arranges and classifies the spring and summer emer- 

 gences of the many forms hitherto included under the typical 

 Euchloe {Anthocharis) helia, Cram. Lord Rothschild now proves 

 that Cramer assigned without authority the name bclia to the green 

 and white Anthocharid of the South of Europe, because the Papilio 

 helia of Linnaeus is really the Algerian E. enpheno, L., also a common 

 Proven9al insect in its European form E. eiiphenoides. The name 

 belta falls therefore, and ausonia, Hiibn. (1803) = simplonia, Freyer 

 (1827) — " the alpine single-brooded subspecies " — becomes the name- 

 type. 



Lord Rothschild, adopting the trinomial form of nomenclature of 

 the ' List of British Birds,' and dropping the "var." altogether, then 

 proceeds to arrange the species into two groups : the first, the single- 

 brooded ; the second, the double-brooded ; the whole comprising 

 twelve geographical races, and the respective spring and summer 

 emergences, some of them named for the first time. 



This classification I reproduce, so far as it relates to European 

 forms, as I think it will be of special value to many of us who have 

 taken the butterfly, or received it from collectors in its several 

 European areas of distribution. I observe Lord Rothschild main- 

 tains the generic Euchloe throughout both for the "orange-tips" and 

 the green and white Anthocharids of other systematists : — 

 Group i. 



(1) Euchloe ausonia, Hiibn. Alps, and E. Pyrenees. 



(2) Euchloe ausonia oherthilri, Verity. Western Pyrenees.
