PAPILIO. 225 



Alis fusco-nigricantibus ; fascia lata communi a margine interne- posticarum ad anticarum apicem extendente, 

 hujus cellulse partem occupante oehracea in anticis, praecipue ad apicem, venas nigras divisa ; posticis 

 lunuli8 septem submarginalibus, ea ad angulum apicalem pallide oehracea, ea ad angulum analem rubra, 

 reliquis obscure ochraceis ; maculis alteris obscuris discalibus ocbraceis, ea ad marginem internum glauca : 

 subtus ocbraceis, anticis apice et margine externo fuscis, hoc lunulis sex includente, cellula fusco longitudi- 

 naliter striata ; posticis lunulis septem discalibus nigris lunulis glaucis includentibus introrsum plus minusve 

 rubido marginatis, margine externo et cauda nigris, ciliis inter venas ochraceis, lunula anali rubida. 

 $ alis viridi-nigricantibus ; anticis fere immaculatis squamis quibusdam et lunulis ad angulum analem evanescen- 

 tibus ochraceis ; posticis fascia discali, cellulae finera vix occupante, ad marginem internum decrescente 

 glauco-virescente, serie duplici lunularum submarginalium paulo saturatioribus, lunula anali rubida: 

 subtus fuscescentibus ; anticis squamis ultra cellulam et lunulis submarginalibus obscure ochraceis ; 

 posticis ultra cellulam nigricantibus, lunulis submarginalibus ochraceis (ea ad angulum analem excepta 

 rubida), lunulis alteris interioribus squamis sparsis compositis glaucescentibus, serie tertia lunularum 

 discali rubida, ciliis inter venas angustissime albis.

It has of late been considered that there is only one species of Papilio of this form 

 ranging over the greater portion of Tropical America. Judging from the males alone 

 this would appear to be the case, but when the females are also examined it is found 

 that several races exist which are localized, and are, as a rule, not difficult to recognize. 

 The males and these females received several names from the older authors, all of 

 which, however, apply to South-American forms, and not one of them to that of our 

 country, which has a female distinct from any of the rest, and hence the necessity for 

 an additional name. Unfortunately our series from Guiana is not sufficiently good to 

 enable us to decide which of the older names is applicable to that form, but it must be 

 either P. androgens or P. polycaon or P. piranthus. 



The South-Brazilian form must certainly pass under the name of P. laodocus of 

 Fabricius, but the Colombian and Amazonian forms are probably unnamed. 



In Mexico and Central America only one form prevails ; the females from the 

 Mexican State of Durango and from Panama differ but very slightly from one another. 

 So far as we know there is no trace of any dimorphism in these females, but in the 

 Amazons valley and Guiana it would appear from Cramer's figures that two forms at 

 least are found. This, too, is Mr. Bates's view. Both in Mexico and Guatemala 

 P. ejpidaurus occurs on both sides of the mountain-range. The females appear to be 

 everywhere very scarce, or at least difficult to find.
