Upper margin of furrow of chelicerce with three teeth as in Lycosa; 

 lower margin with three teeth, of which the median one is stoutest 

 and some longest, the first well separated from it but the third 

 contiguous with it at base, the latter tooth reduced but not so much 

 as in most Pardosas. Labium clearly wider than long (6.5 : 6) ; basal 

 excavation one-fourth the total length; strongly attenuated anteriorly, 

 the sides straight or toward the middle weakly concave, anterior mar- 

 gin truncated or very slightly convex. 



Legs with tibia + patella of fourth pair of same length as the meta- 

 tarsus ; tibia + patella of the first legs of same length or a little shorter 

 than the cephalothorax ; tarsi clothed as usual ; spines of anterior tibiae 

 as usua. (PI. VIII, figs. 7 and 9.) 



Epigynum pentagonal in form, its anterior portion triangular; 

 posterior foveas relatively small, abruptly depressed, each roughly 

 pentagonal in shape with the longest side along the septal piece of 

 guide ; lateral ridges behind narrow, converging but rather widely sep- 

 arated behind, not bent abruptly inward toward each other as in atra. 

 (PI. XIII, fig. 5.) 



Total length, 7 mm. Length of cephalothorax, 3 mm. ; width, 2.3 mm. 



Length of leg I, 8.1 mm. ; tib. + pat., 2.8 mm. ; met., 1.9 mm. 



Length of leg II, 8.1 mm. 



Length of leg III, 9 mm. 



Length of leg IV, 12.1 mm. ; tib. + pat., 3.7 mm. ; met., 3.7 mm. 



Male. — Cephalothorax darker than in the female, the median band 

 obscure and usually not at all evident except caudally and about the 

 dorsal furrow; lateral pale bands narrower and more obscure and the 

 marginal dark line or stripe wider. Chelicerce black or brownish black 

 except distally and along the mesal surface. Sternum entirely black. 

 Abdomen above entirely black, showing no markings; venter dusky 

 brown to gray black; pubescence, as also of cephalothorax, as in female. 

 Legs with femora above black or nearly so except distal, also usually 

 paler beneath; more distal joints of two anterior pairs of legs pale, with 

 faint annuli or entirely unmarked, the corresponding joints on the 

 posterior legs darker but also with markings faint. Palpi entirely black 

 except the patellae which are light brown. 



Tibia of palpus a little longer than the patella and stouter distally. 

 Scopus very long, curving obliquely forward and outward quite across 

 the bulb. (PI. XIII, fig. 6.) 



Total length, 6.5 mm. Length of cephalothorax, 3 mm.; width, 

 2.1 mm. 



Length of leg I, 8.7 mm. ; tib. -f pat., 3 mm. ; met., 2.2 mm.
