produced anteriorly as a tongue-like process between the eyes of the 

 third row, this process divided by a median black line produced back- 

 ward from in front; behind the third eye row the median band is 

 abruptly extended laterally on each side, the widened region being nearly 

 though not fully as wide as the third eye row, the band then again 

 abruptly narrowed until but half so wide, continuing of this width 

 about the dorsal furrow, then passing down the posterior declivity 

 and narrowing to an acute point near the posterior margin; on each 

 side a marginal light band which extends for the entire length and 

 attains the clypeus in front, the band interrupted and sometimes 

 obscured by brown spots; clypeus pale, but with a triangular black 

 spot below each anterior lateral eye, the apex of the spot, as usual, 

 being upward and contiguous with the black surrounding the eyes. 



ChelicercB light reddish yellow; each at base with a black mark or 

 line which passes obliquely outward and distally, and with a larger 

 mark parallel with the first beginning at the inner side near the middle 

 and running obliquely outward and distally. Labium and endites with 

 yellow background, which in each case is nearly covered over by a 

 central black area. Sternum yellow with a large black spot on each 

 side extending from the middle to the front margin, leaving the 

 median area yellow; behind with numerous minute dark dots. Coxm 

 of legs beneath smoky yellow. Legs reddish yellow, all joints except 

 the tarsi with rather heavy black rings, these rings being incomplete 

 on the femora along the postero-inferior face except at the distal end. 

 Palpi colored like legs, but annuli less heavy. Abdomen above and on 

 the sides black with numerous minute reddish yellow dots; dorsum 

 at base with a reddish-yellow spear-shaped stripe reaching caudad to 

 the middle; near each lateral margin of the basal stripe toward the 

 front is a row of two or three black spots, and each side of its apex is an 

 obliquel,y placed angular light spot enclosing a central black spot; on 

 the posterior portion of dorsum a series of several chevron-marks, 

 each seemingly formed by the coalescence at the mesal line of two black 

 centered, angular light spots such as found each side of apex of the 

 basal mark; venter yellow, darker about the sides and caudad and 

 with a median dark stripe as wide as epigynum in front, but narrow- 

 ing to a truncate end behind and not reaching to the spinnerets. 

 Epigynum light reddish brown. 



Sides of face nearly straight, steep but not vertical, in height con- 

 siderably shorter than the length of the chelicerse. 



Anterior row of eyes much shorter than the second, not extending 

 more than between the centers of eyes of the latter, gently procurved ;
