Females from Utah thus far seen differ a little from the type form in 

 the shape of the epigynum. The blunt process at distal end of guide in 

 avara proper is absent in this variety, and the lateral ends of the trans- 

 verse arms extend foi-ward beyond the middle of the fovese (PL 

 XX, fig. 4). 



Locality. — Utah !.

 Female. — Cephalothorax with the tegument marked with a broad 

 median band which is wider than the eye area and covers clypeus in 

 front; this band constricted back of eye area and again, more strongly, 

 at posterior limit of pars cephalica, back of which its edges are irregu- 

 lar or toothed, and widening triangularly down the posterior declivity, 

 across the lower border of which it is united with the broad lateral bands 

 of the same color; the pale lateral bands extending forward only to the 

 pars cephalica, with upper margin toothed ; except for these light bands 

 the cephalothorax is dark chocolate-brown; in life the cephalothorax 

 is densely covered with white and gray hair intermixed in spots and 

 streaks, radiating more or less from the dorsum laterally. Chelicerce
