Metatarsus, that tarsal joint which is next to the tibia. Dr. 

 Williston urges the abandonment of this term as etymologic- 

 ally incorrect. 



Preapical bristle, a large bristle found on the outer third 

 of the tibia in some families of Acalypterae, it is quite distinct 

 from the tibial spurs and is placed on the outer surface of the 

 tibia. 



Pulvilli, two pad-like fleshy cushions, attached to the last 

 joint of the tarsus below the claws. 



Tarsus, the division of the leg beginning at the outer end

Tibial spurs, one or more distinct bristly spines terminating
