Attention is called to the fact that bristle extending from the 

 distal end of joint 3, in the seven-jointed variety, was not found in 

 any of the 13 specimens examined of the six-jointed variei}-, 

 extending as would be expected from the middle of the long 3d 

 segment. The long 3d segment always bore hairs at distal end 

 and nowhere else.
