5. The Intervals between Successive Ovipositions. 
In the Hast three sections, the effect of virginity 
was so clear that it was not necessary to consider the 
effects of other factors. That such factors exist is 
obvious from the variations shown by fertilized fe- 
t/ 
males as well as by virgins, though to a smaller 
extent. These factors cannot be neglected with safety 
in this portion of our investigation and I shall 
attempt to separate them by considering their in¬ 
fluence on the oviposition of the fertilized females in 
some detail. 
TABLE VIII.
