Geographical Distribution of European JRhopalocera. 485 



Genus Thais. 

 This small genus is confined to South Europe, with the excep- 

 tion of T. Cerisyi, which most commonly occurs in Asia Minor. 



Genus DoRiTis. 

 D. Apollina, the only species, appears to be confined to the 

 south-east of Europe and to Asia Minor. 



Genus Parnassius. 

 The metropolis of this mountain genus appears to be Siberia. 

 P. Apollo ranges from Spain to Central Asia. P. Delius extends 

 throughout Northern Asia to California, where the Siberian spe- 

 cies, P. Nomion and P. Clarius, also occur. 



Genus Aporia. 

 A. Cralcegi ranges eastwards to Amoorland. 



Genus PiERis. 



Pieris is, like Papilio, a great tropical genus, and consequently 

 but sparingly represented in Europe. P. Brassicce, Rupee and 

 Napl are met with throughout Europe, Asia and North Africa ; 

 and the range of P. Daplidice is hardly less extensive. P. Cat- 

 Hdice, a mountain insect, ranges from the Pyrenees to Kamt- 

 schatka. 



Genus Anthocharis. 



A. Bella occurs in France and California. It is rather singular 

 that Menetries does not notice it as occurring in any part of 

 Asia. A. Tagis ranges from France to Kamtschatka. This spe- 

 cies, like many others, presents a Corsican sub-species. A. Car- 

 damines occurs from Ireland to Amoorland. 



Genus Zegris. 



Z. Eupheme, the commonest species, ranges from Spain to the 

 Kirghis Steppes. 



Genus Leucophasia. 

 This genus demands special notice, as it is a moot point whether 

 the five described species are really good species, or merely varieties. 

 Premising that the typical L. Stnap'is occurs commonly from Eng- 

 land to Amoorland, I shall give as concisely as possible the cha-
