Sternum and coxcb of legs beneath immaculate yellow. Legs yellow; 

 all joints except the tarsi more or less distinctly banded with black 

 rings; these dark rings on femora of first legs confluent and also semi- 

 confluent on other joints; femora with four rings, of which the apical 

 one may be indistinct. Dorsum of abdomen black, at sides minutely 

 punctate with yellow; at base a lanceolate yellow mark, on each side of 

 which just behind middle is a small ovate yellow spot with black dot at 

 center, and each side of apex a larger triangular yellow spot ; behind is a 

 series of yellow transverse bowed or chevron-shaped transverse marks 

 which become successively shorter caudad, the last few being diamond 

 shaped and contiguous by their apices; sides of abdomen above like 

 sides of dorsum, but below becoming more and more yellow, the black 

 being first reduced to spots and then quite disappearing at venter; 

 venter yellow, dusky in front of the genital furrow and also with a 

 dusky interrupted median band extending back from epigynum two- 

 thirds the distance to the spinnerets, and on each side of venter a 

 narrow irregularly edged black line which does not extend all the way to 

 the spinnerets behind. Spinnerets yellow. Epigynum reddish yellow. 



Sides of face of moderate steepness; face a little more than half as 

 high as the chelicerse are long. Seen in profile, the dorsal line of the 

 cephalothorax is straight and horizontal or nearly so between the eyes 

 and the posterior declivity, the pars cephalica not being elevated at all 

 above the pars thoracica. Lower margin of furrow of chelicerce with 

 three teeth, of which the middle one is much stoutest and longest, the 

 first one clearly the smallest; the upper margin with three teeth of the 

 usual proportions. Labium slightly longer than broad (5 :4.8), 

 four and five-tenths times longer than its basal excavation strongly 

 converging anteriorly; anterior margin indented mesally with its side 

 parts convexly rounded. Legs with tibia + patella of the fourth pair 

 much longer than the cephalothorax, which is of the same length as the 

 tibia + patella of the first pair; spines of anterior tibiae very long, 

 those of the first pair to or a little beyond the middle of the joint. 



Anterior row of eyes but slightly procurved, shorter than the second ; 

 anterior median eyes about two-thirds their diameter apart, closer to 

 the lateral eyes which are two-thirds as large, hardly two-thirds tlieir 

 diameter from eyes of second row; anterior lateral eyes three-fourths 

 their diameter from front margin of clypeus, their diameter or slightly 

 more from eyes of second row; eyes of second row two-thirds their 

 diameter apart; quadrangle of posterior eyes slightly wider in front 

 than long, longer behind than in front in ratio of 9 : 7 (nearly), one- 

 fourth as long as the cephalothorax.
