constricted proximally. The first segment articulates with the 

 tibia by a joint much like that between femur and trochanter. 

 On the ventral surface of the first tarsal segment of the meta- 

 thoracic leg is a soft, membranous pad, projecting distad be- 

 tween the two stout, laterally placed claws (fig. 72) . This pad 

 is best developed in the metathoracic tarsi and these claws are 

 found only here. 



The second segment bears the claws, which are similar in all 

 three pairs of legs. These are short, heavy, and rather blunt.
