no markings and no dark color except on the mandibles and 

 male palpi. The middle eyes are a little farther apart than 

 in crassipalpis. The male mandibles 

 (fig. 54) are narrower than in crassi- 

 palpis and without the sharp ridge on 

 the outer side, but on the inside they 

 are sharply hollowed out with a ridge 

 between the thick outer and thin inner 

 portions. The male palpi (fig. 53) have 

 the patella about as long as wide, as it 

 is in crassipalpis and canadensis, but the 

 tibia is very large, with a hook in the 

 usual place on the outer side and a 

 much larger process, which extends forward over 

 the tarsus. The tarsus is long and thickened 

 in the middle where it rests against the process 

 of the tibia.

 without markings. The upper eyes are nearly 

 equidistant, as they are in crassipalpis, but 

 the leers and palpi are shorter. The male man- FiGs.55,56, 57. ciubi

dibles (fig. 56) are much like those of crassi- head of female, show 

 palpis, but have not so sharp a ridge on the 

 outer side. The male palpi (fig. 57) have the 

 patella longer than wide and the tibia wider 

 than long, with two processes on the outer side. The upper 

 tibial process is a simple point extending along the outer side 

 of the tarsus for quarter of its length. The under process is 

 twice as long, with a projecting corner at its base and running 

 forward to a sharp point, with a round notch halfway between 

 the point and base. The female has the head wider and the 

 mandibles very much swelled in front at the base (fig. 55). 

 The fourth leg is longest and about as long as the body.
