length of the third, which is longer than the second; white submarginal bars rather 

 larger than above ; cell a little longer than vein R^. 



? not known. 



Scent-organ : no modified scales on SM- of hindwiug, the scales upon this vein 

 being the same size and colour as those in front of and behind the vein, P. xynias 

 differing in this respect remarkably from all its allies. 



Eiirly stages not known. 



Hub. Bolivia and Peru, eastern slopes.

c??. Buffish grey dots on occiput, pronotum, palpus and coxae. Spination of 

 legs rather heavy. Wings, beneath, with two red spots at base of forewing, one in 

 cell and the other before it, and three basal spots on hindwing, the second situated 

 in cell being often vestigial or absent. 



Very variable in both se.xes ; forewing of male with a whitish or buffish band 

 or patch on upperside e.\ tending from inner margin forward, being seldom vestigial, 



Hindwing of male with a discal series of red patches in most specimens, 



sometimes only one or two distinct jjatches present on upperside, situated near 

 abdominal margin ; cell rather narrower in middle than in the allied species. 



In tlie female the forewing has usually one or more white patches on disc and 



often a small patch in cell, but is sometimes all black. A red discal band on 



hindwing, variable in width, often entering cell. 



Scent-organ : basal third of vein SM^ densely covered with small greyish 

 scales. 



Genitalia : c?. Apical lobe of harpe short ; ventral lobe of dorso-ventral ridge 

 slightly curved upwards in a view from the base of the clasper, obliquely rounded ; 

 central process spatulate, dentate, usually rounded at ape.x, but sometimes obliquely 

 truncate. 



Early stages not known. 



Hal). Colombia to Bolivia, and eastwards to the Guianas,Par;C, and the Brazilian 

 province of Goyaz. 



AVith the excei)tion of the form from Goyaz, the subspecies do not appear to be 

 sharjily defined. In the case of species individually so variable as /*. ariarathes it 

 requires a large material from many districts to obtain a correct view of the 

 geographical variation. The material 'of P. ariarathes which we have seen in 

 various collections is not quite sufficient for this purpose. Therefore we are not 

 sure that our division of P. ariarathes into six subspecies is quite true to nature. 

 The species varies in different localities according to the models mimicked, the 

 females from different districts being generally more obviously different than the 

 males.
