I was obliged to neglect the colony for several days and as a re- 

 sult it perished. 



This queen laid a total of 302 eggs, from which but 1 1 adults were 

 reared ; 1 1 individuals disappeared in the pupal stage, 30 in the 

 larval stage, and 228 in the egg stage. Not all the young that dis- 

 appeared in this case were eaten by the queen, as it sometimes hap- 

 pened that they were placed in the condensed moisture around the 

 sponge and spoiled. 



It is not possible to get the exact length of the stages in this col- 

 ony, since some of the eggs disappeared before any had hatched, some 

 of the larvcT disappeared before any had pupated, and some of the 

 pupie disappeared iDefore any adults emerged. However, if we as- 

 sume that the hrst 6 eggs passed through all the stages and became 

 adults, the stages would be as follows : 



For the first egg, 48 daj's 

 For the next 2 eggs, 40 days 

 For the first larva. 21 days
