resembling closely those of old unpaiuted wood. The ground color 

 is dirty white and the under side is almost entirely of this color. 

 The dark portion of the back of the abdomen is darkest at the 

 edges and does not entirely cover the abdomen, showing a lighter 

 band around it, plainest around the hinder half. The principal 

 middle markings are a long oval spot in front, pointed before and 

 behind, and a herring-bone pattern behind. The legs are spotted 

 with tine spots closest along the front of the femora and largest at 

 the ends of each joint. PI. xxxi, fig. 1. The males are darker 

 and longer legged, as in most species, fig. 1«. The epigynum has 

 two openings, between which is a ridge that widens behind and 

 extends to the transverse fold. Usually this ridge has waved or 

 irregular sides, as in fig. 1/', but in some the sides are rounded.

The male palpus is long with the tibia nearly twice as long as 

 wide. The lateral process is as wide as long, square at the end, 

 with the upper corner slightly hooked. The under process is smaller, 

 rounded on the inner corner, and sharp pointed on the outer. PI. 

 XXXI, fig. \e. The tarsus is twice as long as wide and pointed 

 at the end. The tube is short and very thick at the base. It starts 

 on the middle of the inner side of the bulb and extends around the 

 end. Under the tip of the tube is a short fine process. Fig. Id.

Female 5 or 6""" long. Abdomen usually about twice as long as 

 the cephalothorax. The Avidest part farther forward than in most

 covered with fine spots. Abdomen dull red at the sides and bright 

 yellow in the middle with a dark greenish marking in the middle of 

 the front half and two dark marks behind it on the hinder half. 

 PI. XXXI, fig. 2. The eyes are surrounded by distinct light rings. 

 In some specimens, usually immature, the abdomen has a more dis- 

 tinct jellow and red pattern. Fig. 2a. 



The male has the cephalothorax and legs darker and the abdomen 

 less bright red and yellow than the female, and sometimes gray and 

 iridescent. In alcohol it shows a more distinct herring-bone pat- 

 tern on the hinder half. Fig. 2 J. 



The male palpus has the tibia nearly as long as the tarsus. The 

 lateral process is unusually long and the upper corner has a sharp
