Plate '19;" fig? 14 
Carapace testaceous, unmarked. Sternum dusky brown or black- 
ish. Labium and endites dusky, pale across tips. Legs pale yellow; 
femora with a wide dusky ring near one third the distance from the 
distal end or in less deep shade including also the distal portion; 
posterior patellae darker and the posterior tibiae with darker annulus 
at distal end. Abdomen whitish yellow; venter with a black area 
immediately back of the genital furrow but this typically not extend- 
ing to spinnerets, weakly dusky over each anterolateral corner and 
caudad from there over upper portion of each side; dorsum with a 
fine median longitudinal dark line extending from in front of middle 
caudad and sending off laterad a number of pairs of fine branches, a 
row of from two to four black dots on each side caudad of the middle, 
these two rows somewhat converging toward the spinnerets. 
Carapace broad and low; groove longitudinal, distinctly impressed, 
crossed behind by a vague transverse impression. 
Posterior row of eyes distinctly recurved as usual; median eyes only 
five eighths their diameter apart, two and a half times their diameter 
from the laterals. Lateral eyes subequal, contiguous, raised on a 
common low black tubercle. Anterior row of eyes slightly recurved; 
median eyes a little longer than the posterior medians (diameters as 
5:4), their diameter apart, once and a third their diameters from the 
laterals. Area of median eyes wider in front than behind in ratio 
14:11; wider than long in about ratio 14:13. 
Sternum slenderly extended caudad between the posterior coxae. 
Legs abundantly aculeate or spined as usual; two rows of spines 
on anterior face of tibia IT shorter and distinctly stouter than those 
found elsewhere. ; 
Patella of palpus above at distal end with two long slender spines. 
Process of eymbium undivided, somewhat clavately expanded distad, 
moderately curved.
