 Legs, 4312; differing but little in thickness. 



This species has the cephalothorax only moderately high, 

 the highest point being at the dorsal eyes, from which it slopes 

 in both directions, much more steeply behind than in front. 

 The upper surface of the anterior thoracic part forms a crescent- 

 shaped plate as in parvula, and from this the drop to the mar- 

 gin is still more abrupt. The sides are vertical and parallel in 

 the cephalic part, rounding out from above below and also 

 widening somewhat in the thoracic. The first row of eyes is 

 straight, which is unusual in this genus. The quadrangle 

 of the eyes is a little wider in front than behind, is one-fourth 

 wider than long, and occupies about one-half of the cephalo- 

 thorax. The third row of eyes is not quite as wide as the 

 cephalothorax at that place, and the eyes of this row are 

 rather large. There is a distinct post-ocular depression. The 

 falces axe vertical and stout with a small fang. 



The cephalothorax is dark reddish brown with white 

 bands on the sides and a white band running from the dorsal 

 eyes around the curved thoracic plate. The abdominal mark- 

 ings are best seen under alcohol, the pattern becoming indis- 

 tinct when the spider is dried. The general color is dark 

 brown. On the front end are two oblique bands of reddish 

 yellow, almost orange color, from the inner side of each of which, 

 behind, comes off a band which bends inward, giving some- 

 what the effect of a parenthesis. There is a pale band down 

 the middle of the dorsum which widens behind and is 

 broken into chevrons on the posterior half. Just behind the 

 inner branches of the yellow bands is a pair of white spots, and 

 on the posterior part, on either side of the band of chevrons, is
