 which widens costad, its inner edge crossing cell at or just beyond base of R'" ; this 

 band emphasized on umlerside by a row of wliite patches, one of which occni)ies

c??. Forewing below withont a bufKsh white patch across the cell, the discal 

 patch just entering cell in most males, being absent from other males and from the 

 female (only one seen) ; the male bearing usually a huffish white discal patch also 

 on upperside, the patch being here much smaller than below and much shaded with 



black. The last red spot of the submarginal row of the hindwing stands distally 



of the large spot which is at its discal side. Hindwing much shorter posteriorly 

 than in F. anchisiades, tail more or less distinct, narrow. 



Genitalia : S. Harpe non-dentate, its dorsal edge more strongly rounded near 

 the apical process than the ventral edge 



Early stages not known. 



Hab. Chiriqui to Bolivia. 



The geographical forms are not quite constant. 



As previous authors did not strictly distinguish P. isidorus from P. rhoJoMctus, 

 we have discarded all references which appear doubtful. 



a. P. isidorus c/tiroins subsp. nov. 



S. Forewing, npperside, with bufiish white spots R-— M-\ the first one minute, 

 the third not quite reaching M=, a small si)ot in cell ; on underside, these jJatches 

 all large, the cell-sjwt being the smallest, the triangular spot R-— R' coming next 



in size,^ while patch R^— M' is the largest, being about twice as long as broad. 



Hindwing, above, with the two red spots R^— R^ merged together; discal spots 

 R^— M- of underside well marked, not separate from the submarginal ones. 



Hab. Chiriqui.

b. P. isidorus briscs subs]), nov. 



S. Forewing, underside, with greyish white spots R^— M= or R'-— M=, upper 



spot small ; no s])ot in cell. Hindwing, above, with two red spots R'— M', 



the pro.ximal (= discal) portion of spot R-— M' about as large as the distal 

 (= submarginal) portion ; on underside the discal portions of spots R^— M- standing 

 separate from the submarginal ones, small, vestigial.
