12 NORTH AMERICAN BUTTERFLIES. 



Naples yellow, and these bands are repeated, but the outer marginal 

 are more or less dusted with yellowish, and the upper four yellow spots 

 on the hind wings are overwashed with orange ; inside this band, still 

 in the black margin, is a band of bluish spots, against the lower three 

 of which, on the inside, are orange spots. The sides of the body are 

 striped with yellow. 



Habitat, Eastern U. S. to the Mississippi Valley, thence south- 

 west to Texas, north into British America to Alaska, also Ontario, Que- 

 bec and Newfoundland. Flies in Florida from April until November; 

 in New England from June until September. 



In Florida, both sexes of specimens of this species which I have 

 seen, are very dark in color, the yellow being decidedly ochraceous of 

 the same shade as in P. cresphontes ; the bandings are heav}% and the 

 upper surface of the hind wings lacks the sub-marginal bandings of blue 

 spots almost entirely; showing that this is not an approach toglaucus. 

 On the other hand, in northern Mass. the reverse is the case, the yellow 

 being paler and the bandings comparatively narrow, with the blue well 

 indicated. 



Glaucus Linn. Melanotic female. This is a black form in which 

 the pale markings in the outer margin remain as in the type, and the 

 blue markings are more extended, but the remainder of the wings is 

 more or less blackened ; occurs from New York, southward and westward. 



16. PAPILIO EURYMEDON Be. 



Pale Y'ellow Swallow-tail. 

 Similar to P. turnus in size, form, and general markings, but the 

 tails are rather more slender, the yellow of the ground color is very pale, 

 often nearly Avhite beneath, but the dark bandings are fully as black as 

 in turnus, and only the two lower of the yellow marginal crescents in 

 the hind wings are tinged with orange, while there is no orange within 

 the blue band. The marginal band of yellow spots below, on the fore 

 wings are fused together, making a continuous band, interrupted only 

 by the narrow veinings. The bandings are wider above and below. Fig. 

 8, b. The larvae appear to differ somewhat from those of turnus. E.x- 

 pands 3.50 to 4.00. 



17. PAPILIO RUTULUS Bd. 



Western Yellow Swallow-tail 

 Form and size of P. turnus and the markings are about the same; 

 the color, however, is deeper, being almost as dark as that of the Florida
