the antennae of the parent individual of this fraternity. The 

 stem parent of this isolation, or subline, had a very high antennal 

 ratio, however. 



The results of selection in this line are well represented graph- 

 ically in Fig. 4, which shows the relations of the fraternal means 

 to each other, and to the extreme variants of the different 

 fraternities. Further data in regard to the individuals obtained 

 in isolation 7 are found in Table IV.

SHOWING LENGTH MEASUREMENTS OF INDIVIDUALS IN ISOLATION 7, AVERAGE 



LENGTHS OF THEIR ANTENNA, THE RATIO OF BODY LENGTH TO ANTENNAL 



LENGTH, AND THE COMPUTED RATIO FOR THE FRATERNAL MEAN. 



Again, we fail to see any hereditary influence shown in regard to 

 a fluctuating character, or variation. Further tests were made.
