P. asclepio quoque affinis ; subtus lunulis internis nigris introrsum late saturate ferrugineis, extrorsum quoque 



late caeruleis ; lunulis submarginalibus omnino saturatioribus. 

 2 mari similis, supra posticis lunulis submarginalibus nullis.

At first sight P. syedra closely resembles P. asclepius, the band crossing the cell 

 retaining a nearly uniform width to the costa, instead of becoming narrow as in 

 P. electryon. The black lunules across the secondaries beneath have on the inside 

 wide dark maroon edges, and the bluish scales beyond them are more numerous and 

 more diffused than in either of the allied species. The female has no submarginal 

 yellow lunules, and thus differs from that sex of P. asclepius at first sight. 



Its range is probably restricted to the mountainous portions of Costa Rica and 

 Chiriqui. Mr. Champion's specimens were taken at an elevation of about 3000 feet 

 above the level of the sea. 



M. P. daunus group.

There is no definite fold near the inner margin of the secondaries in this group, and 

 the edge is not so decidedly hairy as in the preceding groups. The inner margin, too, 

 is concave. The foliate appendage to the front tibia is attached nearer the proximal 

 than the distal end of that joint. In P. daunus the harpes are subtriangular, the lower 

 edge is produced into a long sharp spine, and the outer edge is irregularly serrate 

 (see Tab. LXXII. fig. 9). In P. pilumnus the spine is not so long, but the serration 

 is deeper near the angle from which the spine proceeds (see Tab. LXXII. fig. 10). 

 P. americus exactly resembles P. maehaon in the shape of its harpes ; they are of a 

 linear form, the distal half of the upper edge being distinctly serrate (see Tab. LXXII. 

 fig. 8). The external parts of the female are more highly chitinized and of more 

 singular form than in any other group of American Papilio we have examined. 



This group alone of those found within our region is of decidedly northern affinities, 

 and it also has, in P. maehaon and its allies, connections in the Old World.
