14 NORTH AMERICAN BUTTERFLIES. 



19. PAPILIO PILUMNUS Bd. 



Broad-banded Swallow-tail. 

 Size and general form of P. turnus but with the three tails of dau- 

 nus, Fig. 9, c, and the colors are much as in that species, but there is 

 one less bar on the fore wings, caused evidently by the fusing of the 

 divided second band ; in fact, all of the black markings are greatly wid- 

 ened. The orange spot on inner angle of hind wing above is extended 

 into the next outer cell, and all the marginal spots above on this wing 

 are tinted with it; the orange inside the blue band is also more extended 

 Expands 3.80 to 4.50. Habitat, Arizona and Mexico. 



20. PAPILIO CRESPHONTES Cram, 

 Yellow-banded Swallow-tail. 

 Size, large. Tails, long and enlarged terminally enclosing a yel- 

 low spot, Fig. 10, c. Above, dark velvety brown with a band of ochre- 

 ous yellow spots crossing the wing from apex of fore to base of hind ; 

 another crosses from upper border of fore to inner angle of hind, thus 

 the two on the fore wing form a kind of cross. On inner angle of hind 

 wing is a yellow spot, overwashed with orange, and above it is a bluish 

 crescent. Beneath, these bandings become so greatly enlarged that the 

 dark area is reduced to a central band, a marginal band, and a band 

 and some rather defused lines in the central cell of the fore wings, the 

 base of the hind wing is thus wholly yellow. The black band on hind 

 wings encloses a blue band. There is an isolated spot of black in the 

 termination of the central cell on a line with the black band, and the 

 two upper branches of the middle vein are two orange spots. Fig. 10, c. 

 Body, yellow, with dark line down back. Expands 5.35 to 5.50. Hab- 

 itat from Mass., where it is rare, to Fla., and in about the same range 

 west; has been taken in Ontario, Quebec, and St. Johns, N. B. 



•21. PAPILIO TIIOAS Linn. 



TnoAS Swallow-tail. 



Size, about that of P. cresphontes but the fore wings are longer and 

 more pointed, and the tails are longer, Fig. 10, b; color, similar, but 

 there is an isolated spot of yellow on the lower side of the outer third 

 of the central cell of fore wings above. This is repeated below but larg- 

 er, and the dark lines in the cell are sharply defined. On the hind wing 

 below, the orange spots in the center of the wing arc restricted, but the 

 black band is widened inwardly, so as to include the enlarged, black,
