meet, but being at the 

 same time careful not to 

 crumple the wings, and 

 so produce a false sound. 

 He will then, without fail, 

 hear the sweet secrets of An- 

 tiopa, which are beautiful and 

 delicate in expression, recalling 

 the trickle of a brooklet." 



Now that may be all very well 

 for the European Antiopa, but it 

 won't work on the American in- 

 sect. I sometimes have fancied 

 that I could hear a certain faint 

 squeak from the moving wings not 

 only of the Antiopa but also of 

 the Semicolon butterfly a sound 

 distinct from the mere rustle of 

 the wing. But if our insect does 

 serenade with its wings, as stated, 



its method is not as above described. I don't know 

 from experience just how the European Antiopa is built, 

 but there is no such " file " to be found upon the wing
