o This total represents 10.5 per cent of all the weevils put in the cage. 

 b This total represents 27.7 per cent of all weevils put in the cage. 



It is hardly probable that a majority of the weevils may have 

 been counted upon two or more dates, but the fact that dead weevils 

 were found clinging to the wire (PL VII, fig. 1) at the time of each 

 examination indicates a considerable mortality among the active 

 weevils and that the places of the dead ones in successive counts 

 were taken by weevils wliich had become active since the preceding 

 examination. The percentages of active weevils for the three local- 

 ities show a rather significant difi^erence, and are given for the sake 

 of this comparison without presuming to state correctly the actual 

 percentage of weevils placed in hibernation wliich remained active 

 during the winter in the respective localities. At Dallas the 2,406 

 weevils counted during the winter constitute 7.8 per cent of the total 

 number placed in hibernation. At Calvert the 2,085 active weevils 

 constitute 10.5 per cent of the 19,408 placed in the cage. At Vic- 

 toria the 6,143 active weevils constitute 27.7 per cent of the 22,463 

 in the experiment. Since approximately the same number of exam- 

 inations were made in each locality the differences in percentage 

 indicate in a general way the relative activity in these sections of
