Cephalothorax rather low and flat, narrow in front, widest in 
the middle (monticolus) or behind (siticulosus, piraticus). Eye 
region occupying about 2-5 of the cephalothorax, equally wide 
in front and behind or (monticolus) a little wider behind. Front 
eyes in a straight row, the middle less than twice as large as 
the lateral. Second row a little nearer the first than the third. 
Third row nearly as wide as the cephalothorax. Sternum 
rounded in piraticus, truncated in monticolus, and much atten¬ 
uated in siticulosus. Front coxae separated by more than the 
width of the labium in monticolus, by less in the other species. 
Labium plainly longer than wide. First leg enlarged, with tibia 
cylindrical. Tibiae of first and second with scanty unpaired 
spines, excepting tibia of first in siticulosus. 
This genus is represented by three species from Colorado, 
Texas and California.
