TABLE XIV 



Summary of Tables X to XIII, showing the percentage of male-laying females that occurred among 

 the females which were without food for the first 6 to 71 hours after hatching, and also the percentage 

 of male-laying females which occurred among the females that were abundantly supplied with food from 

 the moment they hatched. 



Tempertitnre 20° to 22° C. 



2 Temperature l^ to l^° C. 



Experiment II, October 29. Two female-laying females were 

 reared at this temperature and their daughter-females isolated. 

 Thirty-five daughter-females were without food from 11 to 64 

 hours after they left the egg, and 49 were abundantly supplied 

 with food as soon as they hatched. 



The detailed results are shown in Tables XV and XVI while 

 Table XVII gives the summary. 



The difference between the percentage of males produced by 

 those starved and those fed is not very great and probably means 

 nothing. 



5 Temperature 2J° to 26° C. 



Experiments III, October 31. Twenty-six female eggs from 

 several individuals were produced at this temperature and as soon 

 as they hatched the young females were starved from i to 13 

 hours. 19+ per cent of these starved females produced male 

 eggs- 

 Tables XVIII and XIX give the detailed history and Table XX 

 gives the summary.
