black; a median reddish-yellow band of the usual form enclosing the 

 V-shaped mark in front; on each side also a yellowish supramarginal 

 stripe with uneven upper edge and limited below by a narrow dark 

 marginal stripe, this stripe not extending forward beyond the cervical 

 furrow; cephalothorax with sparse, short dark hairs, no marginal lines 

 of white pubescence. Chelicerce reddish yellow, clothed sparsely with 

 light gray hair. Labium and endites reddish yellow, paler distally. 

 Sternum and coxcb of legs beneath reddish yellow, sparsely provided 

 with mostly stiff blackish hairs, the former often blackish along sides 

 and pale mesally. Legs brownish yellow, all joints excepting the tarsi 

 with more or less distinct dark annulations, or these sometimes very 

 indistinct on or absent from the metatarsi. Abdomen above blackish; 

 at base above a yellow lanceolate median stripe extending caudally to 

 the middle; each side of the apex of the lanceolate stripe is a yellow 

 spot and behind is a number of transverse yellow marks, each of which, 

 has in most cases the shape of an open angle with the apex directed 

 forward, but more rarely the marks are nearly straight; each side of the 

 median markings of the dorsum above described is in life a series of 

 white spots formed of bunches of white hair, the dorsum elsewhere 

 being sparsely clothed with short yellowish hairs and more scattered 

 long dark bristles; a narrow yellow stripe or row of yellow spots passing 

 over each antero-lateral angle caudally, breaking up over the side into 

 more scattered yellow dashes; this yellow stripe on front of sides often 

 partly masked by white hair, but this hair never forming a very distinct 

 or extensive line or stripe; venter pale yellow to grayish, a darker 

 median line behind epigynum, hair of entire venter yellow. Spin- 

 nerets light brown. 



Seen in profile the dorsal line of the cephalothorax is nearly horizontal, 

 notched at dorsal groove. The chelicerse about one and one-fourth times 

 the height of the face. 



First row of eyes nearly as long as the second, nearly straight; 

 anterior median eyes less than their radius apart, closer to the evi- 

 dently smaller lateral eyes; anterior lateral eyes less than their 

 diameter from front margin of clypeus, some more than their diameter 

 from eyes of second row ; quadrangle of posterior eyes one-fifth as long 

 as the cephalothorax. 



Labium longer than wide (7 : 6) ; basal excavation a little more than 

 one-fourth as long as the labium ; sides below straight and but slightly 

 converging, more strongly converging and more rounded above; front 

 margin substraight, being very slightly bowed forv/ard. Legs with the 

 tibia + patella of the fourth pair clearly longer than the cephalothorax.
