Female. — Sides of the cephalothorax brown to black with lighter 

 radiating lines; a yellow median band widening from behind, where it is 

 a mere line, forward and enclosing the usual dark bifurcate mark in its 

 front half; on each side a yellow supramarginal stripe which does not 

 extend upon the pars cephalica and which is limited below by a black 

 marginal line; in life there is a marginal line of white hair. Chelicerce, 

 labium and endites dark reddish brown. Sternum dark brown, paler 

 along middle and darker at lateral margins. Legs brown, often of green- 

 ish hue, the cox(e beneath paler, yellow. Palpi like the legs, paler at the 

 base. Dorsu?n of abdomen brown of greenish tinge; a basal lanceolate 

 median stripe; two rows of light spots clothed with white pubescence 

 on each side of the basal stripes and extending to the spinnerets 

 behind, the outer line often evidently only caudally, the spots of the 

 inner lines largest anteriorly connected by some thin cross-lines of white 

 hair; sides of abdomen yellowish brown tinged with green; venter 

 clear yellow, sometimes a few small black dots in front of spinnerets. 

 Epigynum reddish brown. Spinnerets yellow. 



Chelicerce one and one-third times the height of the face, the sides 

 of which are subvertical as in Pardosa. Anterior row of eyes a little 

 shorter than the second, a little procurved; eyes of second row nearly 

 their diameter apart; quadrangle of posterior eyes one-fifth as long as 

 the cephalothorax. Lower margin of the furrow of the chelicerce armed 

 below with three teeth. 



Total length, 4 mm. Length of cephalothorax, 1.8 mm. 



Length of leg I, 4.8 mm.
