from the laterals. Lateral eyes equal in size, their radius or scarcely 

 more apart. Anterior row of eyes recurved; median eyes larger 

 than the posterior median eyes (11:8.5), just their diameter apart, 

 farther from the laterals. Area of median eyes wider in front than 

 behind in the ratio 6: 5 and wider in front than long in the ratio 10: 9. 



Lower margin of furrow of chelicera with three teeth of which the 

 most proximal is largest; upper margin with three teeth of which 

 the median is much the stoutest and longest. 



Sternum with caudal portion narrowly triangular as in the suc- 

 ceeding species, and the caudal process similarly narrowly truncate. 



Spines of legs sparser, short and slender. 



Female. Length, 8 mm. Length of cephalothorax, 3.2 mm.; 

 width, 2.7 mm. 



Locality. — Huadcjuina, 5,000 feet, July. (Type, M. C. Z. 215, 

 one female, not quite adult).

Cephalothorax low, only moderately convex; head low; thoracic 

 groove deep, longitudinal. Abdomen in outline from above subtri- 

 angular. 



Carapace yellow of very dilute brownish tinge. Sternum and coxae 

 of legs beneath yellow. Legs testaceous, the femora with a wide 

 dusky ring at distal end and one near middle with in some legs a nar- 

 rower one near base, these rings in the female type not sharply limited, 

 the dusky color being more or less diffused, but in the male more 

 sharply defined; tibiae with three broad dusky rings between which 

 the dark color may also be more weakly diffused; metatarsi of pos- 

 terior pairs with three annuli of which the proximal one is least dis- 

 tinct, these less clearly defined on the anterior pairs; tarsi with a 

 submedian dark annulus. Abdomen above dark greyish brown, 

 embracing numerous fine dots and spots of white, several pairs of 

 transverse dark lines running from outside a little caudad of mesad
