straight, the outer side regularly convex. Femur with a short 

 stalk, the inner side very slightly convex, behind obliquely wi- 

 dened from the stalk, the hinder margin nearly straight; femur 

 altogether nearly parallel-sided. Tibia with a moderately long, 

 somewhat curved stalk, considerably shorter and but a little broader 

 than femur, elongate, behind slightly and regularly convex, in 

 front somewhat abruptly widened from the stalk, the front mar- 

 gin moderately convex, a little concave towards the extremity, 

 altogether but little narrowed towards the tip. Hand with a rather 

 long stalk, with obliquely rounded base, the anterior side strongly 

 convex, behind slightly convex or nearly fiat, on both sides pas- 

 sing gradually into the fingers; the hand is only a little broader 

 than the tibia. Fingers robust and narrowing distally, rather 

 strongly curved, considerably longer than the hand, both fingers 

 on the inner margin provided with numerous, truncate teeth, 

 closely set. 



Mandibles of rather small size, the stem nuich shorter than 

 the moveable finger; the outer side of tlie fixed finger nearly 

 straight; the moveable finger with some small teeth on the 

 inner margin in the distal half, the fixed finger with similar 

 small teeth along the whole inner margin. The moveable finger 

 with a curved, stylet-shaped galea, with some very minute teeth 

 at the extremity. 



Legs with moderately long, pointed hairs; the femora of the 

 two posterior pairs very broad. The coxa I. provided with a 

 small, brown point at the exterior corner. Claws simple.
