Assuming that the first larvae hatched from the first eggs, we have 

 the following egg periods for the first 27 larvse : 



For the first egg, 47 days For 



" " next (1), 47 days " 



" " " (1), 44 days • 



" " '• (3), 43 days 



" (1), 42 days 



" " " (1), 40 days 



" " " (1), 41 days 



" " " (5), 39 days 



" (1), 38 days 



On the same basis we find that the length of the larval stages for 

 the first 15 larvse are as follows: 



For the first larva, 16 days 



For the next few that transformed the time was still longer, but 

 could not be determined exactly since some of the larvae disappeared. 

 The pupal stages for the first 1 5 adults are as follows : 



For the first (1), 22 days 



" next (3), 23 " 



" " " (2), 24 " 



" " " (1), 25 " 



" " " (1), 26 " 



" " " (1), 37 " 



For the next (1), 29 days
