bending dark line each side of middle, the two of which are united by a 

 cross-bar just at base of spinnerets. Spinnerets dusky orange. Epigy- 

 num reddish brown about spermathecal openings, elsewhere concolor- 

 ous with the venter. 



Pars cephalica long and high, highest anteriorly and visibly descend- 

 ing caudad to the pars thoracica. Chelicerce a little longer than height 

 of face. Anterior row of eyes as described for genus; anterior median 

 eyes two-thirds their diameter apart, fully their diameter from the 

 lateral eyes which are about two-thirds as large, their diameter from 

 eyes of second row; anterior lateral eyes their diameter or some less 

 from front margin of clypeus, one and one-half times their diameter 

 from eyes of second row; quadrangle of posterior eyes one-third or more 

 the length of the cephalothorax (PI. XI, fig, 8). Lower margin of 

 the furrow of chelicerce armed with two stout conical teeth which are 

 subequal; upper margin with three teeth of usual character. Labium 

 clearly wider than long (5 : 4); the basal excavation little or not at all 

 more than one-fifth the total length; sides strongly converging anter- 

 iorly; front margin truncate or slightly convexly rounded. Legs hav- 

 ing tarsi bent or curved down at distal end but not at base as in male; 

 tarsi sparsely setose and scopuliE entirely absent. Posterior spinnerets 

 widely separated; distinctly longer than the anterior, but in alcohol 

 often bent toward each other and then inconspicuous; the second 

 joint distinct but short, bluntly pointed. 



For form of epigynum see PI, XII, fig. 2. 



Total length, 3.4 mm. Length of cephalothorax, l.G mm.; width, 

 1 mm. 



Length of leg I, 4 nmi. ; tib. -|- pat., 1.4 mm. ; met., .95 mm. 



Length of leg II, 3.8 mm. 



Length of leg III, 3.8 mm. 



Length of leg IV, 5.5 mm.; tib. + pat., 1.7 mm.; met., 1.5 mm. 



Male. — Lighter than female, markings of legs (excepting the anterior 

 femora) and of abdomen less distinct or absent. Palpi black; the 

 tip of tarsus yellow, in life clothed, like legs, with white hair 



All tarsi of legs distinctly curved downward distally, the anterior 

 ones strongly so, those of the third and fourth pairs also. bent at 

 proximal end. Palpus with the sides of tibiae parallel, not at all 

 enlarged distally; tibia longer than patella by one-fourth its length; 

 tarsus of about same length as tibia + patella, much wider than the 

 tibia (4 :2.5). 



For palpal organ (drawn out from alveolus) see PI. XII, fig. 3. 



Total length, 2.6 mm. Length of cephalothorax, 1.5 mm.; width, 

 1 mm.
