O NORTH AMERICAN BUTTERFLIES. 



10. PAPILIO BEEVICAUDA Saund. 

 Short-tailed Swallow-tail. 



Similar to P. indra but the inner band of yellow spots are more re- 

 stricted, are more or less tinged with orange on the lower surface in the 

 male and on both surfaces in the female, while on the lower surface of 

 the hind wings in both sexes, the outer band of crescent shaped spots 

 are also tingd with orange ; the orange spot on the inner angle of hind 

 wings occupies only the upper two thirds of the light area, the lower be- 

 ing yellow, and the central dot is small, while the tail is longer, Fig. 6, 

 c. The body is spotted as in asterias. Expands 3,00 to 3.52. 



Habitat, Newfoundland, Anticosti, Labrador, and Quebec. Oc- 

 curs in June. 



11. PAPILIO BAIRDII Edw. 

 Baird's Butterfly. 

 Similar in form and size to P. asterias, but the male differs above 

 in having the inner row of yellow spots which cross both wings expand- 

 ed into a wide, continuous band as in indra and brevicauda, interrupted 

 only at the veins. Beneath, this band is slightly tinged with orange on 

 the hind wings but there is no orange whatever on the outer band. The 

 blue band is more restricted both above and below, and the interspace 

 between the two light bands toward the upper border of the fore wings 

 is dusted with yellow scales, The tail and orange spot with its black 

 center closely approximating the black of the inner side are much as in 

 asterias. Fig. 6, b, Female scarcely differs from that of asterias above, 

 but may be recognized by the absence of orange on the outer band of 

 yellow spots on the hind wings, and there is but a slight tinting of this 

 on the inner band. Expands 3.00 to 4.00. Habitat, Arizona. 



12. PAPILIO ASTERIAS Fab. 

 Black Swallow-tail. 

 Above, black with two rows of yellow spots crossing both wings, 

 between these on the hind wings is a rather Avide band of blue and the 

 lowermost spots on the fore wings of the inner band are blue. Within 

 the bands near the apex of fore wings are two small spots, and at the 

 outer extremity of the central cell a transverse band of yellow. There 

 is a spot on the inner angle of the hind wings, orange above, yellow be- 

 low, inclosing a black center: Fig. 6, b. Beneath, the markings are re- 

 peated with the yellow spottings enlarged, the lowermost on the inner 

 band of fore, and both rows on hind wings are overwashed with orange.
