1476 THE BUTTERFLIES OF NEW ENGLAND. 



about the broods at the south and perhaps when known they will throw 

 light upon this point ; whether north or south further experiments with 

 rearing the insect are likely to shed most light upon all the obscure points 

 in its history. Does the pencil of hairs on the hind tibiae of the male dis- 

 tribute any odor from the coxal gland, and if so of what nature? What 

 is the parasite whose presence is known, and are there others?

From flower to flower the boy it led, 



He still pursued the pretty thing. 

 Away it sprang from bed to bed. 



Now sipping dew, now on the wing. 

 And to the fields it took its flight: 



He thought the prize was worth the chase, 

 O'er hedge and ditch, with all his might. 



He followed up the pleasing race.
