THE PIERIDS 



which it was hung. The species is double-brooded 

 in the far North and many-brooded in the South; 

 it winters as a chrysalis. See Plate III for early 

 stages. 



Far out at sea — the sun was high, 



While veered the wind and flapped the sail ; 



We saw a snow-white butterfly 

 Dancing before the fitful gale, 

 Far out at sea. 



Above, there gleamed the boundless sky ; 



Beneath, the boundless ocean sheen ; 

 Between them danced the butterfly. 



The spirit-life of this vast scene, 



Far out at sea.

THE ORANGE-TIPS 



These, like the butterflies comprising the preceding group, 

 are white, marked with black. Their most characteristic fea- 

 ture is the presence on the lower surface of the hind wings of 

 a greenish network, or a marbled green mottling (Plate XIII, 

 Fig. 8). This usually shows through the wing so as to appear 

 as a dark shade when the wings are seen from above (Fig. 

 29). Many species have a conspicuous orange spot on the 

 apical portion of the front wings. This has suggested the 

 common name orange-tips for the group. But it should be 

 remembered that some species lack this mark, and that in 

 some others it is confined to the males. Nearly all of our 

 species are confined to the far West.
