Jndging from a small series of specimens of this apparently rare insect — rare 

 in collections at least — we come to the conclusion that the differences between the 

 types of ilus (Jones's figure), hostilius and guaco are individual, not specific or 

 geographical. 



3 ? . Close to P. bfcinchus, of which it is perhaps a southern form, the patches 

 of the forewiug being, however, in a different position. Forewing with or without 

 bufiish white spot in cell ; two or three patches of the same colour behind cell, 

 patch M- — SM- being the largest; distal margin with small white spots, except at 



apex. Hindwing : a row of red spots from R- or U' to abdominal edge, the spots 



variable in size, separate from cell or close to it, larger in female than in male. 



Underside : forewing black-brown, patch M- — SM- vestigial or distinct, but 

 always smaller than above. Hindwing with four basal spots as in P. belesis and 

 braiichus ; discal spots much paler than above, being more or less whitish pink, at 

 least proximally. 



Early stages not known. 



Hab. Northern Venezuela; Colombia: Sta. Marta and Valdivia ; Panama: 

 Lion Hill and Chiriqui.

133. Papilio branchus Uoubl. (184(3). 



Papilio branchus Doubleday, Ann. May. N. II. xviii. p. 373 (1846) (Honduras). 



J ? . Some spots on occiput and collar red ; frons usually black, often with 

 two red vittae ; a white dot laterally on forecoxa, a jiink or red dot each on meso- 

 and metasternite and at base of first abdominal segment. Va\\A usually with 



white dot or dots. Wings black, opaque, paler below than above. Forewing 



with white patch situated on disc and in cell, separated into two, three, or four 

 spots by the black veins, or this patch absent ; fringe white between veins, but 



these spots often very small, usually absent from apex of wing. Hindwing : a 



broad band of six, seldom seven red spots; spots II- — M- long, situated near cell. 



Underside : white patch of forewing usually a little larger than above, no red 



spot at base. Hindwing : four red spots at base, the posterior one continuous, with 



a line situated on abdominal fold ; red discal spots much paler than above, pinkish 

 white, shading into red distally.
