201 MONOGRAPHIA CHALCIDITUM. 



teen females appeared in the morning, three males and eight 

 females in the afternoon. Two females appeared on the third 

 day, and one on the fourth, making in the whole eighty-two 

 males and twenty-six females. I have seen thirty females and 

 four males emerge from three holes in the middle of a chry- 

 salis of Pontia rapes, and thirty-six females and four males 

 from another chrysalis of the same butterfly ; these last were 

 much smaller than the former. Degeer mentions an instance 

 when one chrysalis produced only males, and another only 

 females.
