Red. Body about twice as long as wide, broadest in the 

 middle, and tapering toward each end; ocelli close together. 

 The cephalothorax with six long bristles, two widely separated

 each side, being close together ; abdomen with a submedian row 

 of four long bristles, one on humerus, and one each side toward 

 tip, and about eight at tip, hardly as long as the others. Legs 

 stout, fourth pair nearly as long as the body, all with many 

 simple hairs ; apical part of femora I and II hardly longer than
