 rounded by a black ring. 



Posterior eyes in a straight line, median eyes a httle smaller than the

 very slightlv procurved Une, median eyes much smaller than the lateral, 

 subcontiguous but separated . from the lateral by their diameter. 

 Median ocular area a little wider than long. Clypeus narrower than 

 ocular area, plane and vertical. 



Chelicerffi dull yellowish, upper margin of the furrow with a row of 

 six teeth lower margin with five smaller ones. Sternum light gray, 

 endites and labium dull yellow. Abdomen as in the male, parts near the

Posterior eyes in a straight line, about equal and equidistant, 

 the intervals between them a little greater than their radius; anterior 

 eyes in a straight line, equally and very narrowly separated, median 

 eyes a little smaller than the lateral. Median ocular area wider than 

 long. Clypeus narrower than ocular area. No auditory hair on fourth 



metatarsus. 



I have examined one of the types of Tfneticus moestus Banks, a male, 



and believe it is a synonym of this species.
