 cephalothorax a uniform grayish black a])pearance. Chelicerce reddish 

 brown to reddish yellow, usually with a black median mark at base, 

 clothed densely with white pubescence, with sparse longer dark brown 

 bristles. Endites yellow or light brown, paler apically, often dusky. 

 Labium deeper colored than endites, dark brown to black. Sternum 

 black, clothed subdensely with short whitish or light gray pubescence. 

 liBgs yellow to brown; on all joints except the tarsi with black annuli 

 which are broadest proximall}', being on the femora often confluent 

 below and laterally, leaving light spots only above ; the legs have usually 

 a bluish or greenish-gray hue proximally, especially on ventral surface. 

 Abdomen with tegument above and over sides bluish black, a black- 

 margined lanceolate mark at base above, followed on each side behind 

 by a row of irregular pale spots; the median region behind, in some 

 with, but in others without, irregular light chevron-marks, enclosing 

 the characteristic dark spots, in some pale specimens entire dorsum 

 and sides with many light spots, irregularly connected above into a 

 network; venter light brown, of bluish to greenish gray cast, rarely

First row of eyes much shorter than the second, but little procurved ; 

 anterior median eyes fully three-fourths their diameter apart, evidently 

 closer to the lateral eyes, than which they are slightly larger; anterior 

 lateral eyes, as usual, twice their diameter from front margin of clypeus, 

 their diameter from e3'es of second row; eyes of second row about once 

 and a quarter their diameter apart; quadrangle of posterior eyes one- 

 fourth as long as the cephalothorax, a little wider in front than long. 

 Chelicerce armed as typical for the genus, having two teeth above and 

 three below with the third reduced. Labium wider than long in ratio of 

 about 9 :8.25; basal excavation one-fourth total length, strongly 

 attenuated anteriorly; the front margin nearly straight, slightly 

 incurved mesally. 



Legs long and slender ; metatarsus of fourth pair longer than tibia + 

 patella of same pair; spines below on anterior tibiae as usual; scopulae 

 of typical form. 



Epigynum with the guide inversely T-shaped ,the median piece pointed
