Cephalothorax very high; thoracic part dilated, at least a third the longer; 

 cephalic part plane or slightly convex, inclined, limited by a very 

 weak transverse stria. 



Clypeus less than half as wide as the middle ej es. 



Eyes of the face rather unequal, in a moderately curved line; the middle 

 not touching; the lateral separated by an interval equal to half their 

 diameter. Dorsal eyes almost as large as the lateral, scarcely further 

 apart. Quadrangle at least a third wider than long. Dorsal eyes 

 equally distant from each other and from the lateral borders. 



Sternum long, rather narrow. Anterior coxae separated by the width of 

 the lip, thicker than the others. 



Falces robust, longer and often a little oblique in the males. 



Palpus ( ,5 ) very slender; patella and tibia equal or the latter the longer 

 tarsus oval, narrow, obtusely truncated at the extremity. 



Legs. ( ^ ) 1, 2, 4, 3; (?) 4, 1, 3, 2. Anterior pairs more robust. Tibia and 

 patella of the first male almost as long, female shorter than the ceph- 

 alothorax; male tibia longer, female tibia and patella equal; tarsus and 

 metatarsus more slender and shor er than the tibia and patella. Tibia, 

 and patella of the third much shorter than tibia and pai ella of the 

 fourth; tarsus and metatarsus of the fourth plainly shorter than pa- 

 tella aod tibia (sometimes of the same length in the males). Meta- 

 tarsus of the fourth armed wit i spines to the base. Tibia of the 

 fourth cylindrical and parallel.

Cephalothorax short, high, the dorsum strongly convex longitudinally^ 

 above, toward the middle dilated and very wide, in front moderately 

 wide, posteriorly very perceptibly narrower. 



Clypeus low . 



Eyes: area occupying about | of the length of the cephalothorax; the 

 quadrangle very wide, much wider than long, wider behind than in 

 front; ante ior row of eyes curved upward; middle eyes not touch- 

 ing, separated from the lateral eyes by an interval at least equal to 

 their diameter; eyes of the second row furthei- from the posterior 

 eyes than from the antei'ior lateral eyes; posterijr eyes not further 

 from the lateral borders than from each other. 



Sternuni scarcely or not wider than the coxae of the first pair; these coxae 

 separated by less than the width of the lip. 



Legs ( 5 ) 1, 4, 2, 3 ; rather robust, without many spines; legs of the first 

 pair more robust than the others, femora compressed anteriorly and 

 and strongly bent above; tibia with patella of the fourth leg longer 

 than tibia with patella of the third. 



Abdomen short .
