'Gephalothorax moderately high; thoracic pirt plainly dilated, at least a 

 third the larger; cephalic part level, often a little limited by a trans- 

 verse depression. 



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



Uyes of the face rather unequal, in a line considerably curved; the middle 

 eyes not touching; the lateral separated by an interval often 

 equal to half their diameter. The dorsal eyes almost as large as the 

 lateral, a little furtlier apart, since the sides of the head diverge 



/ behind. Quadrangle a third wider than loag. Dorsal eyes farther 



from one another than from the late.al borders 



Sternum elongated, rather narrow. Anterior coxae separated by the 

 width of the lip, and much thicker than the others; coxae of the 

 fourth pair a little longer than the intermediate pairs. 



Falees robust and vertical in both sexes. 



PaZpMS ((J ) rather slender; patella longer than tibia; tarsus narrow, oval, 

 truncatefd at the extremity. 



Z,egs (6)1, 2, 4, 3, or 4, 1, 2, 3; {$) 4, 1, 2, 3, or rarely 4, 1, 3, 2; the first and 

 (som times) second pairs more robust with compressed femora. 

 Tibia and patella of the first shorter than the cephalothorax; {$) tibia 

 longer: (?) tibia and patella equal. Tibia and patella of the third 

 much shorter than tibia and patella of fourth. Tarsus and meta- 

 tarsus of the fourth plainly shorter than tibia and patelU. Tibia of 

 the fourth cylindrical and parallel; metatarsus of the fourth with 

 only a circle of spines at the extremity.

Eyes like the genus Marpissa. 



Falees rather long, cylindrical, vertical. 



Palpus in the male rather short, the tarsus glossy, the bulb pointed at 

 the extremity. 



Head and thorax nearest in form to the genus Marpissa. The face in 

 front is as low, and is scarcely higher than the middle eyes of the first
