Habitat. — Macas, Ecuador. One male in coll. B. Preston Clark, re- 

 1 from Dr. O. Staudinger and A. Bang-Haas. 



Closely resembling P. satellitia licaon Cr., but a darker-colored 

 insect, in both its ground tone and its markings. 



The fore wing above lacks entirely the white or pink color along veins 

 Ml and M2, so characteristic of P. s. licaon. The ground tone of the wing is 

 iwnrHlfl color, and the markings are bister. The dark rhomboidal area 

 midway <>f t he inner margin in licaon, is in this species narrow and nearly 

 rectangular. The general appearance of the wing is highly variegated. The 

 hind wing above shows no material difference from licaon, except an entire 

 absence of any pink tinge at the anal angle. 



It is on the under side of this insect that the strongest differences from 

 P. s. licaon come out. The fore wing below has the basal half brown. The 

 two light post median transverse lines of licaon are in this species heavy, 

 with the posterior one deeply lunulate between the veins and the basal 

 one fading away at SM2. The area between these two lines, which in 

 licaon is nearly the same color as the rest of the wing, contains in this species 

 three irregular dark lines, so close together as to give the appearance of a 

 broad postmedian band 8 mm. in width and extending from the costal 

 margin nearly to the inner margin. The distal marginal band of licaon 

 widens to 113, where it attains a width of 9 mm. ; it then narrows abruptly 

 00 R3, and continues still narrowed, and lunulate between the veins, to the 

 hinder angle, where it is 5 mm. wide. The marginal band in this species 

 widens from the wing apex to R2, where it is 10mm. in width, and it retains 

 very nearly this width to the hinder angle, where it is still 8 mm. broad. 

 It is only slightly lunulate between the veins. 



The hind wing below is brown in the basal half. The two postmedian 

 transverse lines are heavy, as on the fore wing, containing between them 

 the three irregular dark lines, the whole forming the same sort of dark band 

 as on the fore wing, 9 mm. wide on the inner margin, and narrowing to 

 6 mm. anally. The basal line fades out anally, and the posterior line is 

 strongly lunulate. The veins are dark between this broad band and the 

 di>tal margin.
