THE SWALLOW-TAILS 



Brave butterfly, what wild ambition filled thy breast 

 To leave thy orange-groves and fling on chilling breath 



Of Northern winds thy golden cross? What race unrest 

 Hath driven thee here to bravely battle frost and death? 



The Green-clouded Swallow-tail 



Papilio trailus (Pa-pil'i-o tro'i-lus) 



Plate IX, Fig. i, 2 



Wings black; front wings with a row of pale straw-colored 

 or greenish spots near the outer margin; and in some speci- 

 mens a part of a second row parallel to this extends from the 

 inner margin. On the lower side this second row is much 

 more distinct. The discal half of the hind wings is profusely 

 powdered with either pale yellow-green or pale blue-green 

 scales, these scales forming a cloud near the middle of the 

 wing. On the upper side of the hind wings there is an 

 orange spot near the middle of the costal margin and one 

 near the anal angle ; and near the outer margin there is a 

 row of six pale yellow-green or pale blue-green lunules. On 

 the lower side there are two rows of orange spots, each row 

 consisting of seven, except that the spot of the inner row in 

 cell M 3 is very small or wanting ; its place being occupied by 

 an extension of the blue or green cloud, which covers the 

 basal part of the area between the two rows of spots. 



This species is found in the Atlantic States and in the 

 Northwest Territories.
