to nearly black. First and second legs yellow. Third legs with femur 

 dusky or brown, yellow beneath at proximal end; tibia dusky or brown, 

 yellowish at distal end; metatarsus also brown, yellow at distal end. The 

 fourth legs with femur darker brown, yellow proximally beneath ; tibia more 

 blackish, yellow at both ends but the distal yellow annulus the larger; meta- 

 tarsus also dark with a yellow annulus at each end. The anterior end of 

 cephalothorax semicircular as usual. Eyes between one-half and three- 

 fourths their diameter apart. Eye-tubercle in front with a number of spines 

 of which two are longer and stouter than the others. Metatarsus of pedi- 

 palps along each edge beneath with a series of five stout and moderately 

 long spines between which and over ventral surface generally are numerous 

 cylindrical setae in part of equal and in part of greater length than the 

 spines, with fewer very long, fine-tipped forms. Tibia with cylindrical 

 setae beneath on distal half. Upper finger of chelicerae bearing beneath 

 three large teeth on the anterior base of the most caudal of which is a much 

 smaller tooth or denticle, the three major teeth being followed by three or 

 four small teeth; this finger along dorsal edge with a ridge which is highest 

 opposite the third, or caudal, large tooth. Lower finger having typically 

 two large teeth with a denticle between them. 

 Length, exclusive of chelicerae, 16 mm.
