First Death. 



Table III shows a great regularity in the date at which the 

 caterpillars at the different humidities ceased feeding. This 

 date can be considered as the beginning of hibernation, as no 

 feeding took place later than this and all molting and meta- 

 morphosis ceased. Since these larvae were exposed to a high 

 temperature and had abundant fresh food present it is apparent 

 that high temperature, abundant food and any relative humidity 

 is not sufficient stimulus to overcome the "tendency" of the
