Table XIV. — Selection of nqnares and relation of feediiiy to ovipositioii. 



A little calculation from these results shows that 82.5+ per cent of 

 all squares attacked received eggs and that 91.7+ per cent of all 

 squares oviposited in received only one egg each. The squares which 

 were fed upon only formed 17.5— per cent of the total number 

 attacked, and those receiving both egg and feeding punctures consti- 

 tute only 3.8 per cent. The squares receiving two eggs each also form 

 3.8 per cent of all the squares which received eggs onl3\ 



The tendency to confine egg and feeding punctures to separate 

 squares is strongly emphasized by the fact that in 17 instances, in 

 which a total of 116 squares was j^rovided, 91 received eggs only, while 

 the remaining 25 were fed upon only; another total of 78 squares 

 received 88 eggs in 72 of them, while the remaining C were fed upon 

 only. As these two lots include nearly one-third of all the squares 

 punctured, the tendency may be clearly seen. 



FIELD OBSERVATIONS. 



For oue series of observations 500 infested squares were picked 

 promiscuously in the field between May 28 and June 9, 1903. 



A i^revious field examination was made about the middle of Septem- 

 ber, 1902, and this furnishes some very interesting comparisons as to 

 the weevil's work upon the squares, especially at the beginning of the 

 infestation and after it had reached its height. To facilitate an easy 

 comparison, the results are arranged in Table XV.
