sternum velvety brown, that of ventral surface of legs similar but with 

 some grey intermixed. Fringe of endites bright copper-red. Pu- 

 bescence of abdomen thick, dorsally and laterally brown, in part more 

 or less of golden lustre. Bristles of legs and abdomen long, in the type 

 mostly curved or wavy distally, of a yellow cast, more brown proxi- 

 mally. 



Eye-tubercle not high. Ocular area just twice as wide as long; 

 anterior row of eyes a little longer than the posterior. Anterior row 

 of eyes viewed from in front moderately procurved, a line tangent to 

 the lower edges of the median eyes touching or intersecting the upper 

 part of laterals. Anterior median eyes with diameter less than that 

 of the laterals in ratio 2:3; two thirds their diameter apart and closer, 

 only their radius, from the laterals. Posterior lateral eyes smaller 

 than the anterior, their diameters comparing as 4: 5; less than their 

 radius from the anterior ones. Posterior median ej'es much smaller 

 than the laterals, the ratio of diameters being about 1.4: 2; subcircular 

 except for the flattening of the anterior side; much closer to the lateral 

 eye than to the anterior median eye. A line tangent to caudal edges 

 of the two posterior eyes of each side intersecting the anterior median 

 eye of opposite side. 



Metatarsi I and 11 densely scopulate to base; metatarsus III scopu- 

 late three fourths the length toward base; and metatarsus IV more 

 sparsely scopulate at distal end only.
