6 alis fuliginoso-nigris certa luce cseruleo lavatis, pra3sertim dimidio posticarum distali ; postieis maculis serie 

 duplici margine externo plus minusve parallelibus, una submarginali luuulatis, altera discali fere rotundis, 

 coccineis : subtus fuliginosis, maculis posticarum ut supra, sed minoribus et omnibus plus minusve nigro

Papilio photinus is an isolated species with no near allies ; though belonging strictly 

 to this group, the sexes so closely resemble one another that the female as well as the 

 male partakes of the blue gloss which pervades the wings in certain incidents of light. 

 It is by no means uncommon in Mexico and Guatemala from the neighbourhood of 

 Mazatlan southwards. Its range in altitude is considerable, extending from the sea-: 

 level to a height of at least 5000 feet. Southward of Guatemala it is apparently more 

 scarce ; Dr. Staudinger possesses specimens from Honduras, and we have but a single 

 specimen from Costa Rica. 



10. Papilio dares.

$ alis brunneo-nigris, ciliis inter venas albis ; anticis macula parva discali supra venam medianam alba ; postieis

Hab. Nicaragua (mus. Hew. in Mus. Brit. 1 2 ). 



We only know this species from the single female specimen in the Hewitson collection. 

 Its position in the genus is somewhat doubtful, but from the slight blue opalescence on 

 the secondaries we think it comes near to P. photinus, differing, however, in many 

 respects, notably in the presence of a small white discal spot on the primaries, the 

 slighter dentation of the secondaries, the greater distance of the outer discal row of 

 red spots from the margin, &c.
