23/ 



Abdomen alcove very dark ; a basal black mark with end behind forked 

 and followed by a series of chevron-marks, all the marks usually 

 indistinct in older specimens, in which the entire dorsum is black or 

 nearly so ; dorsum clothed in life with black and grayish-brown pubes- 

 cence, the lighter pubescence more concentrated anteriorly and antero- 

 laterally, and also forming some mostly obscure transverse chevron- 

 piarks behind; in dark specimens the sides are dark or black-streaked 

 and spotted below with yellow pubescence, with the yellow sometimes 

 predominating over the black ; venter with numerous spots and streaks 

 of yellow pubescence usually arranged mostly in four lines or stripes 

 converging to the spinnerets, and thus dividing the dark into three 

 bands similarly converging caudally. Spinnerets brown. Epigynum 

 reddish brown. 



Face rather low, not fully half as high as the chelicene are long, the 

 latter long and massive, considerably longer than the face is wide in 

 front. Cephalothorax not high, dorsal line highest at third eye row. 

 from there being nearly straight to the posterior declivity. 



Anterior row of eyes as wide as or slightly wider than the second, 

 nearly straight; anterior median eyes less than their radius apart, 

 about as far from lateral eyes ; anterior lateral eyes a little more than 

 two-thirds as large in diameter as the median, once and one-half their 

 diameter from front margin of clypeus, closer to eyes of second row ; 

 eyes of second row a little less than their diameter apart; eyes of third 

 row three-fourths as large as the second, twice as far from each other 

 as from the second ; cephalothorax 6.5 times the length of the quad- 

 rangle of posterior eyes. 



ChelicerfE armed as usual. Labium longer than wide (8.5 : 8); basal 

 excavation as usual ; sides strongly convexly bulging, the curvature 

 less above than below; front margin wide, concave for nearly entire 

 width (PI. IX, fig. 9). Legs stout; tibia + patella IV shorter than the 

 cephalothorax ; metatai*sus IV of nearly same length as the width of the 

 cephalothorax; tarsi I and II slightly curved. III and IV straight; 

 tarsi scopulate as usual, the scopula? on legs I and II extending also 

 over metatarsi and over all but basal portion of tibise ; spines of tibise 

 as usual. 



For structure of epigynum see PI. XVII, fig. 7. 



Total length, 23 mm. Length of cephalothorax, 10.6 mm.; width. 

 8.2 mm. 



Length of leg I, 25.6 mm. ; tib. + pat., 9.3 mm. ; met., 5.1 mm. 

 Length of leg II, 23.2 mm. 

 Length of leg III, 21.5 mm.
