EXPLANATION OF FIGURES 



79, 80, 83, 86 to 90 are from eggs laid by an unfertilized female. The speci- 

 mens were taken from the body cavity of a half grown caterpillar fifteen days 

 after the eggs had been deposited. The body cavity contained four normal and 

 four degenerate asexual larvae, in addition to many masses of sexual embryos.

 after the eggs had been deposited. There were found in the body cavity six 

 free asexual larvae and four larvae still enclosed in their membranes, besides 

 many masses of sexual embryos.
