PAPILIO. 195 



described from a male specimen. It is generally admitted that these names refer to 

 sexes of the same species. According to Felder 3 the butterfly figured by Gray as 

 P. erithalion really represents a female of P. zeuxis of Lucas, also a Colombian species. 

 Messrs. Butler and Druce include this species in their list of Costa-Rican butterflies 2 , 

 but we are unable to find in Van Patten's series any specimens really belonging to it. 

 The most northern point to which we can trace it with certainty is Calobre in the State 

 of Panama. On the line of the Panama railway it appears to be far from uncommon.

Hal. Costa Rica ( Van Patten l ). 



We have three examples of this species, which seems to be quite distinct from all 

 others, having no olive-green patch on the primaries, and only a very small whitish 

 spot in the centre of those wings. We are not acquainted with the female, and of the 

 male the three specimens before us, one of which we figure, are all that we have seen. 

 Its nearest ally is P. cauca of Staudinger from Northern Colombia, but in that species 

 the primaries are spotless.

P. polyzelus is a characteristic species of Mexico, Guatemala, and Honduras, to which 

 countries its range is limited ; here, however, it appears to be abundant from the sea- 

 level up to an elevation of 3000 to 4000 feet. It was described by Felder from 

 specimens obtained by Salle in Southern Mexico 1 . Its most northern limit, so far as 

 we have traced it, is the Sierra Madre de Tepic, where Mr. Richardson recently 

 obtained specimens in crossing the Sierra to Bolafios.
