These notes made during 1911 support with only very- 

 slight variations the phenomena noted above, pointing 

 to the conclusion that four moults occurred between 

 June 22 and Aug. 8. From the table below it is evident 

 that another moult (the first) occures previous to that 

 time, when the insect is 11 to 14 days old. 9
