Eyes: the first row is high over the mouth and strongly b-n% the two mid- 

 dle eyes large, the side eyes in diameter not half as large. The eyes 

 of the third ro v just as large a^ the side eyes of th firrt; those of 

 the second row very small, half way between these two. 



Mandibles very long, nearly equally thick, somewlrat curved on the inner 

 corn r of the extremity, toothed, the fang rather large. 



Palpus: ;hat of the male slender, the second joint bent, the tliird cylindrical, 

 plainly longer th n the fourth, the tarcus long in front, swollen, the 

 bulb covered ' r^ m above. 



Ceplialothorax short and very high, falling steeply from the cephalic plate, 

 rather fiat, with distinct elevations at ihe eyes; also the face is very 

 high, but not equally high in the differenc species, and the first row 

 of eyes high above the mouth. The abdomen is somewhat longer 

 than the cephalothorax, narrow, oblong oval, and equally with 

 the cephalothorax, (the letter, however, only partially) covered 

 thickly with scaly hairs. The spinnerets a e slender and rather 

 long, the legs also are 1 ng; of these the third pa'r is the longest, 

 then follows the first, then the seco.d and after this the fourth. 

 One of the species described by C. Koch and all the Australian species 



described by L. Koch und r this genus have the eyes of the second row 



nearer the anterior than the posterior side eyes and the legs 1, 3, 2, 4, not 



3, 1, 2, 4. See note by Dr. Koch, p. 1170 of the Arachniden Australiens. 



The species pi ced in this geaus by Dr. L. Koch seem to us (judging by his 



plates) to belong to at leisttwo 'f not three different genera.

Eyes form and position as in Phidippus. 



Palpus of the male slender, rather loae, the second joint long gently, 

 slightly bent, the third and fourth short, not longer than thick, the 

 tarsus moderat*"ly long, humped at tHe proximal end, somewhat 

 raised in knots, in the middle on the back somewhat contracted, the 

 bulb covered from above.
