 claws with a few small teeth (? on iirst leg). 



Sternum oval, longer than broad ; muscular scars (sigilla)

 brown hairs, showing, especially on the limbs, strong metallic-blue 

 reflections. 



E>/es of anterior line equidistant and subequal, the diameter of 

 the medians excelling the short diameter of the laterals, but less 

 than their long diameter ; posterior laterals smaller than anterior 

 laterals. 



Length of carapace about equal to length of patella and tibia of 

 1st leg or of 4th leg, the two being substantially equal ; also about 

 equal to the length of the protarsus and half the tarsus of the 4th.

 3rd with about three additional spines, of 4th with only one 

 additional posterior spine ; protarsi of 1st and 2nd with an inferior 

 apical spine ; protarsus of 3rd with a few spines on the proximal 

 side of the scopula and a posterior series above ; protarsus of 4th 

 armed below with some 12 or 13 spines ; protarsal scopula of 4th 

 leg very distinct ; tarsal scopula divided by a very narrow band of 

 setae ; the rest of the lower surface thickly scopulate. Lower 

 surface of mandible covered in its posterior third with a cluster of 

 granules. 



Measurements in millimetres. Total length 36 ; length of cara- 

 pace 17-3, width 13-5 ; length of 1st leg 45, of 2nd 41, of 3rd 39,
