the other joints, and has a fringe of hair on the upper and a 

 stiff brush on the lower edge. The abdomen seems small 

 when compared with the cephalothorax ; there is a constriction 

 in front of the middle, the anterior end being quite slender, 

 while the j^osterior part widens out and is rounded. The 

 pedicle is very short. 



Color. The cephalothorax is bright reddish-brown, with 

 the eyes on black spots ; there is a little fine, white down over 

 the surface, and some white hairs are found about the eyes. 

 The abdomen is of a soft golden-brown color, the anterior portion 

 being lighter than the posterior ; the surface is thinly covered 

 with white hairs, and there is a band of white around the con- 

 striction ; two dark, fine lines cross the constriction in the 

 upper central part, from the anterior to the posterior portion. 

 The legs are light brown, except the femtir of the first, which 

 is darkened ; the palpi are of a darker brown than the legs. 

 The under surface is light brown.
