NOTES ON THE GENUS EUCHLOE, Hubneb, A GENUS 

 OF THE PEERING. 



By A. G. Butler, Ph.D., F.L.S., F.Z.S., &c. 



For many years a number of Palsearctic species stood in 

 collections under Boisduval's generic name Anthocharis ; but 

 eventually it was discovered that this genus was, to all intents 

 and purposes, a synonym of Euchloe, Hiibner, which consequently 

 superseded it. 



Meanwhile, for a single species with strongly falcated pri- 

 maries Herrich-Schaffer proposed the name of Midea, and to this 

 group I subsequently added two species — M. scolymus from 

 Japan and M. limonea from Mexico. (I did not, however, 

 recognize Midea as a genus.) 



When Schatz reviewed the genera of butterflies in Staudinger's 

 ' Exotische Schmetterlinge,' he raised Midea to the rank of a 

 genus, and divided Euchloe (which he called Anthocharis) into 

 two genera, calling the orange-tips Anthocharis and the whites 

 Phyllocharis (entirely overlooking the fact that the latter name 

 had been used in 1824 for a genus of Coleoptera). Schatz 

 figured, and somewhat distorted, the neuration of one species 

 in each group, with the object of showing principally that in 

 Euchloe (= Anthocharis, Schatz) the second subcostal branch, 

 vein 10, is emitted before the end of the cell, and in Phyllocharis 

 after the end : Midea, for which he figured M. scolymus, is re- 

 presented as agreeing with Euchloe with vein 10 before the end 

 of the cell, — a character varying considerably on opposite wings 

 of the same individual, although I believe vein 10 in Euchloe 

 scolymus is never emitted after the end of the cell. 



In June of the present year, Dr. Beutenmiiller published a 

 ' Revision of the species of Euchloe inhabiting America, North of 



ENTOM. — JAN. 1899. B
