PAPILIO. 233 



Hab. Costa Eica (Van Patten 1 ), Cache (Rogers) ; Panama, Chiriqui (mus. Staudinger). 



— ECUADOE. 



Though in general appearance this Papilio resembles P. pandion^ its relationship 

 with that species is not very close. The shape of the hind wings, with their deeply 

 dentated margin and their prominent tail, at once separates the two forms; the band 

 on the primaries, too, is narrower and more definite in P. rhodostictus, and crosses the 

 cell some way from the end. The sexes are very much alike, resembling Gray's figure 

 of P. orchamus of Boisduval, which is a species of the P. torquatus group, the male 

 of which is a very different insect. Dr. Staudinger has examples of P. rhodostictus 

 from Chiriqui. We only possess the Costa-Eican types, and a female obtained in the 

 same country by Eogers. There is a male specimen from Ecuador in the Hewitson 

 collection. 



J. P. zagkeus group. 



Papilio, Sect. xlvi v Feld. Sp. Lep. pp. 24, 71. 



The primaries in this section have a smooth costal margin, they are long and rather 

 narrow and rounded at the apex ; the secondaries have an indefinite fold, along the edge 

 of which is a pencil of long black hairs, another patch of yellow hairs spreads over 

 the base of the median nervure and its first branch. The foliate appendage of the 

 front tibia is attached rather nearer the proximal than the distal end of the joint. The 

 harpes of P. zalates are somewhat like those of P. thoas, but the terminal projection is 

 more central (see Tab. LXXI. fig. 3). The sexes are similar. 



Owing to the colour of the wings resembling those of some species of Lycorea, this 

 is a very peculiar group. Its range is limited, extending from the Upper Amazons 

 Valley and Venezuela to Ecuador and Colombia, one species being found in the State 

 of Panama.

This species belongs to the group of Papilio of which P. zagreus is the oldest known 

 form, but its nearest ally is P. aseolius of Felder from Colombia, and so close is it to
