Seven out of the ten records varied from the average by less than 20 per 
cent while three varied by between 25 and 40 per cent. The average 
number of the insects included in the ten records was 72 and the aver¬ 
age variation was 11.2 or 15.5 per cent. In view of these results it is 
considered that there is little if any significance in differences between 
any two baits amounting to less than 25 per cent when the number of 
hoppers included in the record is less than 100. Further it is evident 
that even with a greater percentage of difference than 25 or with more 
than 100 of the insects, there is still a chance that the results from any 
one experiment may be misleading. 
The results of the 109 experiments included in series A to F inclusive
