a In Tables VII and IX the designation "not emerged" is used for those stages and adults which have 

 not left the cells in which they developed. Adults which have previously leit thecells within which 

 they matured and have subsequently sought shelter within any part of the bolls are designated as 

 "emerged." 



Besides showing that large numbers of weevils entered hibernation 

 in or upon these bolls, this table shows that bolls do not provide 

 sufficient shelter to insure the survival of hibernating weevils in a 



winter so severe as was that of 1904-5.
