scribed; such hair as there is on carapace and legs is rust-brown in 

 color. 



Pars cephalica very low; only slightly rising above the level of the 

 pars thoracica. 



Ocular tubercle very low. Ocular area very nearly twice as wide 

 as long (48 : 25) ; the two eye-rows equal in length. Anterior row of 

 eyes viewed from in front only moderately procurved, a line tangent 

 to the lower edges of median eyes intersecting the upper part of the 

 laterals; viewed from above a line tangent to the anterior edges of the 

 median eyes passes near middle of surface of each lateral one. An- 

 terior median eyes much smaller than the laterals, the diameters 

 being to each other as 23 : 38 ; more than three fourths their diameter 

 apart and only about half as far from the laterals. Posterior lateral 

 eyes with longitudinal diameter three fourths or a little more that of 

 the anterior laterals, from which they are separated by less than their 

 radius. Posterior median eyes with long diameter about four fifths 

 that of the lateral eyes; scarcely elongate, truncate behind; a little 

 closer to lateral eyes than to anterior medians. 



Metatarsi I and II scopulate to base; metatarsus III scopulate to 

 middle; metatarsus IV scopulate only at distal end. 



Female (type). Length, 48 mm. 



Cephalothorax : length, 20.4 mm.; width, 18 mm.; length of pars 

 cephalica 12.2 mm.
