stalk, and then moderately and regularly convex. Tibia with 

 a distinct and robust stalk, the inner side much swollen, the 

 outer side slightly convex from the base, more convex towards 

 the extremity. Hand with a short stalk, the base somewhat 

 obliquely truncated, not much broader than the tibia, the inner 

 side slightly, the outer very slightly convex, both sides passing 

 somewhat obliquely into the fingers. Fingers considerably cur- 

 ved, robust, somewhat shorter than the hand, somewhat gaping; 

 on the outer side of each finger 5 to 6 conical teeth. 



Mandibles. Galea in male small, in female somewhat larger, 

 in both 'cases with some teeth in and near the extremity. 



Legs with some dentated and some pointed hairs ; the femora 

 of the two posterior pairs of legs moderately robust. Claws simple. 



Length. 2.4 mm., ç^ and $ of about the same size. 



Measurements.

The measurements, it will be seen, are nearly identical 

 for the two sexes ; with the exception of the sexual organs, there 

 is on the whole, very little difference between male and female 

 in this species.
