ENTEANCE INTO HIBERNATION. 21 



activity, and the general relationship of temperature to conditions of 

 food supply and weevil activity. In the following tables are shown 

 the maximum and minimum temperature occurring throughout the 

 period, which has been approximately determined for each of the 

 localities indicated in the respective seasons. The maximum tem- 

 perature is given above and the minimum temperature below the line 

 for each day. Wlierever the climatic records for a particular locality 

 are incomplete it has been necessary to use those for some other near-by 

 locality. The table shows at a glance the daily range of temperature 

 in each case, which undoubtedly has considerably more significance 

 in regard to the entrance of weevils into hibernation than would the 

 figures showing simply the mean daily temperature. The table as 

 arranged shows a comparison of the records of all localities during 

 each season successively.
