TIME FROM EGG TO ADULT. 
Ill 
The average time required for complete transformation and 
emergence of beetles, as shown in Table LVII, also varies considerably, 
but in view of the variations in season and in the localities from which 
records were obtained are more uniform than had been expected. 
Thus, between the shortest time, 43.05 days (Georgia, 1906), and the 
longest, 57.21 days (Michigan, 1910), there is a variation of only 
14.16 days. The average time for the complete life cycle from egg to 
emergence of adult for all localities is 50.27 days. 
Complete records were obtained, in the case of a few individuals, of 
time occupied from deposition of egg to appearance of adult, as shown 
in Table LVIII. The averages for each locality are based on the 
total number of life-cycle days. The Barnesville, Ga., records include 
individuals from eggs laid each month from April to August, inclusive. 
These are separated in the table so as to show the marked lengthening 
of the life cycle in the earliest individuals, from eggs laid April 8-14.
