the tarsi with black annulations which are usually more distinct 

 proximally and deeper above on femora than ventrally; clothed with 

 brown hair which is also the color of the scopulae. Abdomen above 

 grayish-brown, the pubescence consisting of gray and brown inter- 

 mixed; at base a dark, deeper margined, sublanceolate stripe ending 

 obtusely or bifurcating at the middle, but this basal mark frequently 

 inconspicuous and sometimes absent; posterior portion of dorsum 

 rarely with some dark chevron-shaped cross-lines; a black spot over 

 each antero-lateral angle which is usually followed caudad by a row of 

 dark angular spots and marks along the sides ; sides and venter yellowish 

 or grayish brown, the pubescence, as on dorsum, being light and dark 

 often intermixed in fine spots and streaks; the tegument of venter often 

 showing two pairs of dark lines or stripes converging toward the 

 spinnerets; entire animal darkening with age, the venter then showing 

 usually a broad dark brown to black band over its length from genital 

 furrow to the spinnerets. Spinnerets brown. Epigynum dark red- 

 dish-brown to black. 



Face about half as high as the length of the chelicera?, sides rounded 

 and slanting; width at base less than the length of the chelicerffi. 

 Dorsal line of cephalothorax highest at third eye row, somewhat con- 

 cavated at median furrow. 



Anterior row of eyes considerably shorter than the second (by twice 

 the diameter of a lateral eye or more), moderately procurved; anterior 

 median eyes less than their radius apart; anterior lateral eyes about 

 two-thirds as large as the median, a little less than their diameter from 

 eyes of second row and a little more than their diameter from front 

 margin of clypeus; eyes of second row large, about three-fifths their 

 diameter apart; eyes of third row but little smaller than those of secona 

 (ad. 5:6), more than twice as far from each other as from eyes of second 

 row; quadrangle of posterior eyes between one-fifth and one-sixth the 

 length of the cephalothorax. 



Chelicerce with furrows armed as usual. Labium nearly as wide as 

 long, not much attenuated; front margin concavated. Legs with 

 tibia + patella IV of same length as cephalothorax or a very little 

 longer; metatarsus IV longer than the cephalothorax is wide; anterior 

 tibige and patella armed as usual; tarsi and metatarsi I and II scopulate; 

 tarsi III and IV as usual. 



Epigynum broadly ovate with posterior end widely truncate; side 

 ridges relatively very thick; septal piece of guide in front of enlarged 

 posterior end with sides parallel or nearly so, the femur at its side 

 narrow and not much differing in width from anterior end back to the 

 caudal enlargement of guide (PI. XXI, fig. 7).
