In treating of the members of this genus we have throughout admitted that the 

 females are liable to a considerable amount of variation both as regards the general 

 colour of the upper surface of the wings and the intensity of the markings thereon. 

 According to this view P. rurina, as regards its females, shows great diversity. One 

 extreme form has the upper surface of the wings of a uniform dirty white with a large 

 black spot at the end of the cell of the primaries, and a very narrow dark apical margin ; 

 in the other extreme the wings are pale yellow, and the secondaries have a broad outer 

 border of deep rufous. Between these two extremes we have many intermediate 

 gradations. The pallid females are P. virgo (Butler) 5 , the rufous-bordered females 

 are the typical P. rurina (Felder) 1 , and an intermediate specimen formed the type of 

 Mr. Butler's P. intermedia. All these forms we propose to unite under the name of 

 P. rurina ; but at the same time we note that in the males the orange colour of the 

 basal portion of the primaries and the outer portion of the secondaries is not so intense 

 in northern as it is in typical and Venezuelan examples, though specimens from various 

 parts of our country show some diversity in this respect, and we do not therefore attach 

 much importance to it. 



Regarding the status of the South-Brazilian and Argentine form of this Phoebis, 

 to which the name P. neocypris of Hubn. seems properly applicable (=P. cipris, Fabr., 

 nee Cram., = P. bracteolata et P. irrigata, Butler), we are in some doubt as to its 

 relationship with P. rurina, or whether we have more than one species represented 

 under this name ; but we think that the females in this southern form have their own 

 set of varieties, and that one with dark rufous border to the hind wings is not included
