The gradual decrease in the length of the egg stage following the 
rising temperature is well shown, dropping from the average, 9.83 
days, for April to 3.68 days for July. The average for the four 
months is 6.62 days. 
Table XVIIT gives a summary of the preceding data. There is 
seen to be a range of from 24 days to 134 days for the different 
localities, the averages varying from 3.77 to 9.23 days.
