37. Papilio metaphaon. 



Papilio metaphaon, Butl. Trans. Ent. Soc. 1874, p. 434 \ 



Papilio phaon, Godm. & Salv. Trans. Ent. Soc. 1880, p. 126 8 . 



P. phaonti persimilis, sed anticis lineis subcostalibus ad angulum apicalem viridi-sulphureis ; posticis fascia 

 discali multo majore, grisescentiore et fere totam cellulam occupante. 



Hab. Mexico X (coll. Kaden l ). — Colombia 2 . 



We have some doubts as to whether this Papilio should be admitted into our list ; 

 the title to do so rests upon the label of the type, which was formerly in Dr. Kaden's 

 collection, and marked " Mexico." It agrees almost exactly with the specimen named 

 P. phaon by us in our list of Mr. Simon's collection from Northern Colombia ; we thus 

 think it very probable that this close ally of P. phaon will be found to inhabit Northern 

 Colombia and probably Venezuela, and not Mexico at all. It is only doubtfully speci- 

 fically distinct from P. phaon, but differs in the points mentioned above. 



Mr. Butler, in his description, refers to P. ulopos as its nearest ally. This alliance 

 is more remote. 



38. Papilio ulopos. 



Papilio ulopos, Gray, Cat. Lep. Ins. B. M. p. 69 x ; List Lep. Ins. B. M. p. 80 (1856) 2 . 



P. phaonti quoque similis, sed anticis maculis submarginalibus vix ullis, tribus ant quatuor ad medium mar- 

 ginis externi tantum notatis ; fascia posticarum cellulse finem plerumque occupante. 



Hab. Mexico j (Hartweg 2 ) ; Beitish Honduras, R. Hondo (Blancaneaux), Corosal 

 (Boe) ; Guatemala, Cubilguitz (Champion), Choctum, Polochic valley (F. D. G. & 0. S.), 

 Panzos, Cahabon (Champion) ; Hondueas (mus. Staudinger). 



P. ulopos was based upon a specimen said to have been sent by Hartweg from Mexico 2 ; 

 but we have no confirmation of this statement, all our specimens being either from 

 British Honduras or the lowlands of Vera Paz. Hartweg travelled both in Mexico and 

 Guatemala, and his specimen may have come from the latter country. In Guatemala 

 P. ulopos occupies nearly the same area as P. phaon, and though the two are obviously 

 allied, the former may readily be distinguished from the latter by the submarginal spots 

 of the primaries being confined to the middle of the margin ; those near the anal angle 

 (which are large in the latter) are completely obliterated.

The inner margin of the secondaries is more or less folded in this group, but the fold 

 in P. epidaus is very small and restricted to the proximal portion of the margin, and, 

 moreover, does not appear to enclose a tuft of long hairs, which in the other sections is
