Papilio ornythion, Boisd. Sp. Gen. i. p. 354 \ 



Alis fuliginoso-nigris, fascia communi mediana ab apice anticarum ad marginem posticarum internum transeunte 

 ochracea, in anticis maculis subrotnndis composita, tertia ab apice maculam triangularem includente,

 maculas submarginales quoque ocbracea ; posticis fascia transversa lata nigricante cellulse finem transeunte, 

 lunulis septem rubidis includente, extrorsum nigro marginatis, lunulis albicantibus exterioribus quoque

Hab. Mexico, Yucatan 1 . 



We have never seen a specimen of this species, but through the kindness of 

 Mons. Charles Oberthiir we have before us an excellent photograph procured for us 

 by him, and taken from Boisduval's type still existing in the Museum at Bordeaux. 

 From this it appears that P. ornythion belongs to this section of the genus, and is not 

 really allied to P. thoas, with which Boisduval associated it, although the male has a 

 great similarity to that species; an obvious difference, however, is noticeable in the 

 primaries, which show a row of spots running parallel to and near the outer margin, 

 instead of diverging in the direction of the common ochreous band. As compared with 

 P. pallas, P. ornythion has a very narrow common band, which is broken up into 

 roundish spots on the primaries, and beneath there is an indistinct band of spots 

 between the submarginal row and the common band. As in P. thoas the third 

 ochreous spot from the apex has a dark spot in the middle; this is not found in 

 P. pallas and its allies. 



The female will doubtless prove to be similar to that of P. pallas. 



It is curious that so little is known of this insect ; this may, however, be due to its 

 having been overlooked from its great similarity to P. thoas. At the same time it may 

 prove not to belong to Yucatan at all, but to Cuba, in which case the female may be 

 P. pirithous itself. M. Roger had butterflies in his collection from both localities. 



Our figure has been prepared from the photograph of the type already mentioned. 



58. Papilio, sp.l 



We have two fragmentary male specimens of a Papilio allied to P. pallas — one from 

 the line of the Panama Railway, the other taken at sea a few miles from Punta Mala in 

 May 1873 ; neither of them is sufficiently perfect to enable us to give a full description. 

 They do not, however, quite correspond to any of the forms now before us ; they are 

 larger than our examples of P. theophron, and have the series of lunules within the 

 black transverse band of the secondaries beneath very indistinct, the fulvous row, which 

 is the innermost, being very large, the rest are in consequence narrow. The outer
