The Distribution of the Sexes 



In both cases, the laying is taken as com- 

 plete for the same reasons as those given 

 above. 



We will end with some series that appear 

 to me incomplete, in view of the small num- 

 ber of cells and the absence of any free space 

 above the pile of cocoons: 



These examples are more than sufficient. 

 It is quite evident that the distribution of the 

 sexes is not governed by any rule. All that 

 I can say on consulting the whole of my notes, 

 which contain a good many instances of com- 

 plete layings — most of them, unfortunately, 

 spoilt through gaps caused by parasites, the 

 death of the larva, the failure of the egg to 

 hatch and other accidents — all that I can say 

 in general is that the complete series begins 

 with females and nearly always ends with
