characters given above ; these are more positive in Chiriqui examples than in those from 

 the rest of the State of Panama, where a trace of the whitish spots on the primaries is 

 sometimes present. The size and shape of the olive-green patch of the primaries 

 varies considerably, but never enters the cell ; so too the scarlet spot of the secondaries 

 varies in size, but never approaches the outer margin so closely as in P. mylotes. 



D. P. POLTDAMAS group. 

 Papilio, Sect. viii. Subsect. A, B, C, Feld. Sp. Lep. pp. 9, 51. 



The fold along the inner margin of the secondaries in this group is narrow, the outer 

 portion of the inner surface is covered with short isolated scales, followed by semierect 

 more closely-set scales, and these again by a glabrous elongated patch running along 

 the bottom of the fold. A transverse section of the fold of P. philenor is shown on 

 Tab. LXV. fig. 18. 



The foliate appendage of the fore tibia is nearly in the middle of the joint. 



The harpes of P. polydamas, P. lycidas, and P. philenor are very similar ; they are 

 short, not reaching to the middle of the valve ; at the distal end they expand into two 

 well-developed horns (see Tab. LXV. figg. 14, 17, 18 a). The harpe of P. lycidas is the 

 most distinct of the three, and has a small third horn on the upper edge. 



The general colour of the wings is green, more or less glossy, and in the section 

 containing P. philenor the median nervure of the secondaries generally bears a small 

 spatule. 



Of the members of this group P. polydamas has a very wide range, chiefly in Tropical 

 America. P. philenor belongs rather to North America, and is not found beyond the 

 limits of Mexico. The other species are of more restricted range, and either belong to 

 the more northern portions of South America or are peculiar to our region.
