Fabricius's name was based upon one of Jones's drawings which represented a female 

 Papilio of this form from an unknown locality 1 . With this figure Gray identified 

 specimens from Mexico and Honduras in the British Museum 2 , remarking at the same 

 time that the white spot on the primaries was larger in the figure than in the specimens 

 before him. 



Dr. Felder agreed in this identification 4 ; but Boisduval 8 considered that the 

 description was equally applicable to six or seven species, and in his Lepidoptera of 

 Guatemala named the Mexican species Papilio lycimenes. We adhere to Gray's 

 application of Fabricius's name, the discrepancy in the width of the band of the 

 primaries being of no importance, as is shown in our series of specimens. 



The males of this species vary greatly as to the markings of the primaries. The olive- 

 green spot differs much in size and shape : in some specimens it enters the cell, in others 

 it only reaches the median nervure ; occasionally it passes the submedian in the direction 

 of the inner margin, but more frequently it does not even touch it. So too with the 

 whitish spot, which is sometimes single and nearly round, and is then usually situated 

 in the angle between the median nervure and its second branch, sometimes it passes 

 into the cell, and even beyond it, in the direction of the costa. So also with the red 

 band of the secondaries, which sometimes consists of only three contiguous portions, at 

 others it extends towards the apical angle as isolated spots. Females are also variable 

 both as to the width of the oblique band of the primaries and the number of segments 

 into which it is divided by the nervures. The red band of the secondaries also varies 

 in width. From this it will be seen that P. iphidamas is a very variable species ; 

 moreover the variations do not appear to be in any way localized. In Colombia and
