(J ? . Sexes similar, the female being lari;i'r and paler tliau the male. Forewing 

 resembling that of P. tlioas. Hindwing, below, with a row of rufous red spots 

 around cell ; apex of cell bearing a rufous red spot bordered distally by a black 

 crescent, which is often double, the interspace between the two black lines and 

 the tip of cell being buffisb-yellow ; tail without yellow spot in centre ; marginal 

 spot behind tail large. 



Neuration : SC^ of forewing strongly curved at base, stalk of SC'* shorter than 

 the two cross-veins D- and D^ together, D^ very oblique, sometimes almost in the 

 same direction as D^, lower angle of cell very obtuse. 



Genitalia: cJ. Tenth tergite long, narrowing apicad, apex rounded; sternite 

 laterally incrassate in middle, the incrassation divided transversely into an anterior 

 and a posterior toothlike ridge. Clasper rounded ; harpe broad, rounded distally, 



bearing several long thornlike teeth at the edge. ?. Edge of vaginal orifice 



anteriorly in middle raised into a tubercle which is carinate on the anterior and 

 convex on the posterior side ; behind the orifice a rounded tnbercle which is densely 

 covered with minute hairs ; behind this tubercle two folds extending forward into 

 the orifice ; in front of the orifice on each side a broad shell-like ridge, with 

 irregular edge, and laterally of this another smaller ridge ; on the posterior surface 

 of the large ridge stands laterally of the orifice a long, slender, pointed, thorn- 

 like process. Anal segment on inner surface with ibnr bristles on each side (tliis 

 number constant ?). 



Early stages described by Walker, I.e. 



Ilab. Columbia and Northern Venezuela southward to Bolivia. 



There is no reliable evidence that the species occurs in Chili.
