between, farther forward, at and just behind the middle, the sides of 

 the dark lateral bands simply dentate, the teeth not connected across 

 middle. Sides becoming lighter from above below, the lower portion 

 and the venter rather light brown, the venter appearing to have been 

 somewhat darker down its middle behind lung-slits in life. Spinnerets 

 brown. Epigynum dark reddish brown. 



Cephalothorax highest as usual at third eye only slightly descending 

 posteriorly ; the dorsal line nearly horizontal, a little depressed at dorsal 

 groove. Face with sides sloping moderately, in height about half the 

 length of the chelicerse. Anterior row of eyes clearly shorter than the 

 second, procurved; diameter of anterior median eyes is to diameter of 

 eye of second row as 1 : 2.2 ; anterior lateral eyes once and a half their 

 diameter from margin of clypeus, a little closer to eyes of second row; 

 anterior median eyes their diameter from eyes of second row, and 

 one-half their diameter apart, scarcely closer to lateral eyes (which are 

 scarcely smaller) ; eyes of second row a little more than three-fourths 

 their diameter apart; posterior quadrangle of same length and breadth, 

 wider behind than in front in ratio of nearly 9.25 : 7, and about one- 

 fifth as long as cephalothorax. 



Lower margin of the furi-ow of the chelicerce with two stout and 

 equal teeth; upper margin of the furrow with three teeth, the first of 

 these is low but wide and bluntly rounded, the second as usual much 

 largest, conical and acute, the third of intermediate size, shaped like 

 the second. 



Tarsi of legs not curved, all straight; first two pairs of femora bent 

 forward ; third femora nearly straight, scarcely bent backward ; fourth 

 femora a little bent backward. Scopulx distributed about as usual 

 but rather sparse, divided by setose band on all tarsi !. 



Epigynum 1 mm. wide and about same length {i.e., shorter than 

 any of coxae, the third of which is 1.6 mm. long) (PI. XIX, fig. 5). 



Total length, 12 mm. I^ength of cephalothorax, 5.3 mm. ; width, 

 3.8 mm. 



Length of leg I, 11.6 mm. ; tib. -I- pat., 6.4 mm. ; met., 2.4 mm. 



Length of leg II, 10.9 mm. 



Length of leg III, 10.4 mm. 



Length of leg IV, 14.2 mm. ; tib. -|- pat., 4.2 mm. ; met., 4.2 mm. 



Male. — Coloration very nearly the same as in female. Legs not at all 

 marked, the first and second femora darker than posterior ones, first 

 tibia also darker. Palpi darker than in the female, the tarsi a little 

 darker than other joints. Irmer margins of dark lateral bands of 

 dorsum dentate and serrate, but not with any connecting angular or 

 chevron-shaped marks across middle.
