c?. The middle discal spots and the cell-patch of the forewing on the whole 

 larger and the submargiual spots smaller than in the Colombian form ; hindwing 

 obtusel}- dentate. The cell-patch is very variable, being sometimes almost srpiare 

 and sometimes nearly obsolete; the discal spots also vary mnch in size. Tlie npper 

 submarginal dots of the forewing are nsnally smaller than the posterior ones, the 

 first one being occasionally absent ; the spots around apex of cell mentioned iu 

 Ho2)fter's description are seldom all present. 



?. The two forms are each individually very variable, some specimens standing 

 intermediate between the two forms : 



ci}. ? -f. arclnjtas similar to the male, sjiots of forewing on the whole smaller, 

 if sharply defined, or large and ill-defined. 



i'. ?-f. pantliias nov., markings of upperside more or less greenish or bluish 

 (type of name from Chiriqui). 



Genitalia: 3. Harpe with three apical prongs, there being besides the iisiial 

 two prongs one on the surface proximally of the ventral one of the usual pair ; this 

 additional prong is a prolonged tooth, there being mostly several other but smaller 



teeth between the prongs. ? . Vaginal flap acuminate, dentate, long ; lateral 



processes with several prominent teeth.

(J. Size of cell-patch and of discal spots on npperside of forewing very variable, 

 the cell-patch sometimes absent, usually more oblique than in the preceding 



subspecies ; upper submarginal spots larger than the posterior ones. Width 



of band of hindwing likewise variable, the spots composing it sometimes separated 

 from one another ; tail longer than in 1'. c. arclnjtas. 



On underside the iwsterior submarginal spots of forewing usually close to 

 the discal ones, often joined to them. 



Felder's name clearchus is based on specimens without cell-patch on upperside 

 of forewing, with small discal sjiots, and with the band of tlie hindwing, above, cut
