of the chelicerse being about two and one-half times as great as the 

 height of the face; sides sloping and rounded as usual. Anterior row of 

 eyes slightly procurved, nearly as long as the second; anterior median 

 eyes three-fourths their diameter apart; anterior lateral eyes three- 

 fourths as large as the median, closer to the median than the latter are 

 to each other (2 : 3) ; anterior lateral eyes their diameter from front 

 margin of clypeus and the same distance from eyes of second row; 

 anterior median eyes scarcely more than one-half their diameter from 

 eyes of second row; eyes of second row slightly more than twice as large 

 in diameter as the anterior median eyes (9 : 4) ; quadrangle of posterior 

 eyes as wide in front as long; wider behind than in front in ratio of 

 6.3 : 4.6; between one-fourth and one-fifth as long as cephalothorax. 



Lower margin of the furrow of the chelicerce with three teeth which are 

 stout and conical, the third a little reduced ; upper mai'gin w ith three 

 teeth as usual, the first minute. Labium of usual shape, slightly 

 curved for entire width. Legs with tibia -t- patella IV of same length 

 as the cephalothorax; metatarsus distinctly longer than the width of 

 the cephalothorax; both the posterior and the anterior tarsi with the 

 scopuljB divided by a median setose band, the anterior metatarsi with 

 only sparse scopular hairs. 



Tibia of -palpus of same length as patella and of same thickness 

 proximally, the tibia widening moderately distally; tibia and patella 

 together a little longer than the tarsus. 



For structure of palpal organ see PI. XIX, fig. 1.

Female. — Coloration of the female is nearly same throughout as male. 

 Eye arrangement and general structure as for the male. Legs with 

 tibia + patella shorter than the length of the cephalothorax; meta-
