Length, 2""". Legs orange-brown. Cephalothorax dark brown. 

 Abdomen dark gray with five or six pairs of lighter spots. The 

 mandibles of the male have a row of hooked teeth on the outer front 

 edge. The female has slight traces of the same teeth. The male 

 has a strong tooth on the front of the ends of the mandibles, which 

 is wanting in the female. The male palpus has the til)ia as wide at 

 the outer end as long, with a wide tooth projecting over the tarsus. 

 Fig. 2e. The palpal organ has three teeth attached by the base to a 

 semicircular hard portion of the organ. Fig. 2e. The epigynum 

 has the upper edges united in the middle and prolonged backward at 

 the corners, forming a triangular opening over the rounded middle 

 lobe.

 and more twisted. The three teeth on the palpal organ are not so 

 distinctly united at their base to a horny ridge as in tridentatus. The 

 outer edge of the epigynum, Fig. 46, is deeply divided in the middle,
