empliasis that in our opinion the true position of the five species in question will 

 be far l)etter nnderstoocl if kept together, than if distributed over at least four 

 genera. To serve the understanding of the true relationship, to show the true 

 connection between the species, is the ideal object of classification of animated 

 nature, as ojiposed to mere baptism of the different forms and groups of forms. 



Key to the species : 



a. Breast and legs black .... .554. F.Jiacofasciata. 

 Breast and legs not blai'k . . . . . b. 



b. Distal margin of forewing deejjly sinuate 



below apex, trilobate at R', M' and SM- 5.5-'. P. proserpiiia. 

 Distal margin of forewing very faintly or 



not all concave below ape.^ c. 



c. Underside of abdomen, basal area of hind- 



wiug below, and marginal band of 

 hindwing above, cinnamon-rufous. . 550. P. gaurae. 

 Marginal band of hindwing black, under- 

 side of abdomen and base of hindwing 

 below olive-green or greyish green . . . (/.
