and metatarsi and at the middle of the patellae of the posterior pairs, 

 but which are not present on these joints of the anterior pairs; the 

 dark annuli on the femora mostly incomplete below; the anterior and 

 posterior face of each femur commonly with a longitudinal black line 

 or stripe. Abdomen with a wide pale band over the dorsum, narro wing- 

 usually to a point at the spinnerets ; within the pale band at base a dark, 

 black-edged, lanceolate mark which extends to or often much beyond 

 the middle, ending usually in a forked apex and followed behind usually 

 by a triangular mark and several dark cross-lines; at other times the 

 basal stripe ends acutely; less commonly it is entirely absent; sides of 

 dorsum laterad of light band dark brown enclosing a series of large 

 angular black spots; sides above brown becoming lighter below, usually 

 marked with numerous small black spots ; venter whitish or light yellow, 

 without spots, but in the great majority of cases marked by a black 

 U-shaped stripe, each arm of which has its end behind a lung-slit, the 

 bent middle part being at the spinnerets, the arm of the U-shaped 

 band often connected by a cross-band behind the genital furrow; 

 sometimes the venter is entirely pale without any markings. Epiyy- 

 num reddish brown. Spinnerets smoky brown to black. 



Face moderate in height, the chehcerae about one and three-fourths 

 times as long; sides convex and moderately divergent beloAv. Anterior 

 row of eyes moderately procurved, shorter than the second by twice the 

 diameter of a lateral eye; anterior median eyes their radius apart, 

 closer to the smaller lateral eyes; anterior lateral eyes their diameter 

 from eyes of second row, a little farther from margin of clypeus; eyes of 

 second row their diameter apart, not much farther from the three- 

 fourths as large eyes of the third row ; eyes of third row twice as far from 

 each other as from eyes of second row; cephalothorax rather less than 

 five times the length of the cephalothorax. CheUcerce armed as usual, 

 the third tooth of lower margin of furrow a little reduced. Labium 

 much longer than wide (16 : 12.5); basal excavation of usual length; 

 sides evenly convexly curved from excavations to anterior angles; 

 front margin truncate. Legs long, the distal joints slender, especially 

 so the posterior metatarsi ; tibia + patella IV longer than cephalothorax 

 which is longer than tibia + patella I; anterior tibiae with spines as 

 usual; scopulae of tarsi as usual, those of anterior pairs extending also 

 upon metatarsi except at base ; patella II armed within. 



Ends of transverse arms of guide of epigynum almost always char- 

 acteristically excavated on anterior side of ends (PI. XVII, fig. 3). 



Total length, 14 mm. Length of cephalothorax, 5.4 mm. ; width, 

 4 mm.
