Remarks on family ‘-Papilto.” 
1. Frequently confounded with P. protesilaus^ to which it bears 
close resemblance. Its distinction is not clearly established. 2. It is 
not fully determined whether this species and P. marcellus are varie¬ 
ties, or distinct. 3. A patched-up insect, undoubtedly counterfeit. 
4. Drury’s figure is a compromise between P. fhoas and P. cresphontes. 
5. P. Tnarcellinus corresponds so nearly with this one, that little doubt 
remains of their identity. 6. Closely resembles P. rutulus^ and will 
probably prove a mere variety. 7. A remarkable dark “aberration’’ 
of various shades, of the 9 of P- turnus^ —chiefly confined to the 
Southern United States : north of Pennsylvania the 9 is usually 
yellow; dark S entirely unknown. 8. There is considerable differ¬ 
ence of opinion concerning the identity of P. mareelhis and P. ajax. 
9. % and 9 differ much: insects that have the look of distinct species 
are included under the same name. Some confusion here. 10. Will 
probably prove to be the 9 ofP.daunus. 11. The difference between 
this and P. agesilaus does not seem well established. 12. Good au¬ 
thorities are divided on the question whether P. tJioas be a distinct 
species, or only a climatical modification of P. cresphontes. 13. The 
figure of Lucas represents a dwarfed variety, derived from Hudson’s 
Bay and other northern latitudes. 14. The sexes strikingly vary in 
coloring. 15. The resemblance to P. m,achaon is close. This seems 
hardly more than a variety of that well known European insect. 16. 
Included here on the authority of Menetries. Doubtful as an Ameri¬ 
can insect. 17. P.policenes. by Boisduval (Spec. Gen. p. 261) 
to inhabit the Antilles, is an African species.
