This species, which also has a long white palpus, is much 

 smaller and lighter colored than longi-palpus and pacatus. 



The quadrangle of the eyes occupies more than one-half of 

 the cephalothorax, and is nearly equally wide in front and be- 

 hind. The middle eyes of the first row are a little more than 

 twice as large as the lateral. The clypeus in the male is much 

 higher than the large middle eyes ; in the female it is scarcely 

 half as high. The first row of eyes is curved. The second row 

 is nearer the first than the third. The falces of the male are 

 long, vertical, and nearly parallel, with a strong blunt tooth at 

 the end on the inner side. The fang is strong and rather long. 



The palpus of the male has the tarsus longer than the 

 tibia, and the patella shorter than these two joints together. 

 There is an apophysis at the end of the tibia, on the outer side. 

 The palpus of tlie female is also long, white and slender. 



The general color of the male is light yellow, the abdomen 

 being paler than the cephalothorax and legs. There are white 

 hairs around the anterior eyes and in large patches on the 

 sides of the eye-region. The clypeus seems to be in two parts, 

 the upper being tinged with red, while the lower is blackish. 

 There is a central vertical band of white hairs which reaches 

 from the eyes nearly to the lower edge. The abdomen has a 

 band of white hairs around the anterior end, another down the 

 middle of the posterior half, and some scattered white hairs on 

 the lower sides. On either side of the central white band are 

 two large black spots, and in one specimen there is a third pair 

 of less distinct spots in front of these, and a fourth pair nearer
