male perceived her, he instantly approached without any 
preliminary courtship, leaped upon her back, remained 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 
afew 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 insects at some later 
date.
