Cephalotliorax flattened: cephalic and thoracic parts of the same length; 

 the latter contracted, inclined, truncated or slightly hollowed 

 behind. 



Clypeus less than half as wide as the large middle eyes. 



Eyes of the face sub-touching, forming a straight or barely curved line. 

 Dorsal eyes of the same size as the lateral, not prominent, situated 

 at the widest point of the cephalothorax, much further apart than 

 the lateral. 



Sternum attenuated at both extremities, a little wider than the intermedi- 

 ate coxae. 



Falces short, plane, or a little flattened in front. 



Palpus ( S ) not very long, and not robust; tibia shorter than patella, with 

 an external terminal apophyiis, slender, tarsus oval, relatively nar- 

 row. 



Legs short; the fourth pair longest, the first pair much the most robust, 

 with femur and tibia much dilated, often flattened and claviform. 

 Tibia and patella of the third much shorter than tibia and patella of 

 the fourth; metatarsus and tarsus of the fourth usually shorter than 

 tibia and patella. Legs of the two posterior pairs entirely without 

 spines (except Eenesiens); legs of the two first pairs having below 

 two rows of tibial and metatarsal spines.

Cephalothorax low, flattened on the back; head much longer than wide, 

 perfectly plane above; thoracic part shorter than the cephalic, a 

 little lower behind. 



Eyes of the third row placed very far back; those of the second row 

 nearer the anterior than to the posterior eyes, and nearer each other 

 than are the anterior and posterior lateral eyes. The tops of the an- 

 terior eyes are in a perfectly straight line; the middle eyes are very 

 large, occupying tlae entire width of the face; the external eyes of 

 this row are considerably larger than the eyes of the other rows. 



Falees large, short and almost vertical in the female; long, horizontal, 

 and armed with a long recurved hook in the male.
