male perceived her, he instantly approached without any 

 preliminary courtship, leaped upon her back, i-emaiiied a 

 few seconds, and then voluntarily left her. The female 

 did not make any apparent movement, although I saw 

 quite half-a-dozen males leap upon her in the course of 

 a few minutes. The males never met near her, and I 

 saw no signs of any fighting. I could not tell whether 

 there was any actual pairing, but it is improbable that 

 this could have occurred in so short a time. It is likely 

 that the males found that she was in some way unfit for 

 pairing, and then left her. I have already implied that 

 there was no special display of the beautiful blue under 

 wings for the benefit of the female. 



I trust that I may be able to make further observations 

 upon these beautiful and interesting iusects at some later 

 date.
