 ? . Total length, 6.8 mm. 



Cephalothorax : Length, 2.8 mm.; width, 1.2 mm. 

 Legs, 4312 ; all slender. 



The general appearance is long, slender, nodose. The 

 cephalic part is rather high, much higher than the thoracic, 

 and is slightly inclined forward. Behind the dorsal eyes is a 

 deep constriction, which runs on to the sides. The thorax is 

 arched upward in the median dorsal part and falls very grad- 

 ually behind. The quadrangle of the eyes is one-fourth wider 

 than long, wider behind than in front, and occupies a little less 

 than one-third of the cephalothorax. The eyes of the first row 

 are close together, and are nearly three times as large as those 

 of the second row; those of the third row are half-way between 

 the second and fourth. Tiie dorsal eyes are very prominent, 

 standing out from the sides of the head. The pedicle is rather 

 long. The abdomen has a deep constriction in front of the 

 middle, behind which it rises into a rounded hump and then 

 slopes off. 



Color. The caput is bright golden-brown, with the eyes 

 on black spots; there aie white hairs around the eyes and in a 

 band around the constriction ; behind the constriction the 

 color is darker and more reddish than in front, shading into 

 black at the pedicle; the pedicle is black. The anterior end of 

 the abdomen is black, with a tranverse band of white hairs 

 near the pedicle ; the constriction and the posterior part are 

 pale yellow, almost white. The falces, mouth parts and sternum 

 are pale yellow. The first leg is all white except the tibia, which 

 has a fine, black, longitudinal line on the inner side; the sec- 

 ond is all white ; the third has the coxa, trochanter and proximal 

 half of the femur black ; the distal half of the femur shades 

 into yellow-brown, and all the other joints are white ; the fourth 

 leg has the coxa black, the trochanter white, the femur shaded, 

 as in the third leg ; the patella white ; the tibia yellow-brown, 

 and the other joints white. The palpi are white.
