Egg deposition by individual moths. — Observations were taken on 

 the egg deposition of six individual moths in captivity as given in 

 Tables XVII, XVIII, and XIX. In most of these experiments pairs 

 of male and female moths were used, which were removed from the 

 stock jars before any oviposition had taken place.
