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 ej-e-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 ej^es 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.
