Genera of the Family Attidce. 297 



Legs : patella and tibia of the third shorter than those joints in the fourth 



pair ; metatarsus and tarsus of the fourth somewhat shorter, or 



more often as long as patella and tibia of the fv urth. Spines on all 



the legs, those on the metatarsi of the fourth throughout their 



length. 



In this genus the relative length of the legs is very variable. In the 



species described by Thorell (Studi Rag i, III, pp. 526-642) we find the 



following formulas : 5 1, 3, 4, 2 ; 3, 4, 1, 2 ; 3, 1, 4, 2 ; 1, 3, 2, 4 , 3T 1 2 ; 



1, 2, 3, 4 ; $ 3, 4, 1, 2 ; 1, 4, 3, 2 ; 1, 4, 3, 2. Tne eame is true of the height 

 of the clyp us. In these species the lieight varies from less than J to 1, 

 to i and in one spider almost equals the diameter of the large middle 

 eyes.

Cephalothorax high, on both sides in front, especially in the male, dilated 

 and inflated. 



Cli/peus at least half as high as diameter of middle eyes. Quadrangle of eyes 

 usually occupying ^ of the length of the cephalothorax, nearly 

 equally wide in front and behind, about a quarter wider than long, 

 and narrower than the cephalothorax at that place by three or four 

 times the diameter of the posterior eyes. The line bordering on the 

 upper edges of the anteri' r eyes is more or less strongly curved up- 

 w^ard ; the lafcrral anterior eyes separated by less than their diameter 

 from the large middle eyes , eyes of the second row almost in the 

 middle b.tween the anterior lateral and the posterior eyes; poste- 

 rior eyes further from the lateral borders thaa from each other. 



Sternum rather short, wider thaa the coxee, not projecting between the 

 coxfe of the first pair. 



Falces vertical, ordinary. 



Maxilke parallel, sub-ovate, at least half longer ihan the lip. 



Legs: third pair longer f^an the others (-xcept in some males which have 

 the first leg longer than the others), much longer than the fourth 

 pair ; patella with the tibia of the third longer than patella with the 

 tibia of the fourth. (In the males the first pair of legs is enlarged, 

 and densely haired, at least underneaih.) 



Abdomen sub-ovate. 



' Zenodonis is substituted for Ephippus, the latter name being preoc- 

 cupied.
