Dendryphantes militaris. 



Attus militaris Hentz. Philceus militaris Peckham. 



Female 1 or 8'""' long. The cephalothorax is ^ide across the mid- 

 dle in both sexes, nearly as wide as long. The middle eyes are a 

 little nearer the front lateral than the dorsal eyes. The mandibles are 

 a little flattened in front, and in the male, the front outer corner over 

 the claw is sharp. PI. XVII, fig. la. 



The general color is brown, covered with black, and a few gray 

 hairs, darker and browner than mstivalis. In alcohol it turns red 

 but not so bright as ciestUHdis. The cephalothorax is ])i-own in 

 the female, and in the male the same color, with a white stripe 

 each side under the eyes. Fig. \a. The abdomen of the female is 

 brown, with four pairs of white, oblique marks in the middle, and 

 four at the sides. Fig. 1. The front of the abdomen is white. In 

 the male the middle white spots are absent, and the hiteral and front 

 white marks are united into a band that extends nearly around the 

 abdomen. Fig. \a. 



The palpi of both sexes are very slender, and the tarsi and palpal 

 organs of the male are unusually small for so large a spider. The 

 tube of the palpal organs is hmger than in ct'stivalis -iimX more sim])le. 

 Fig. Id. 



The mandibles of the male are widened at the end, and have a 

 large two-pointed tooth near the end of the claw. The claw has a 

 short, flat tooth on the inner side, near the middle. Fig. \h, \c. 

 The epigynum is like that of aestivalis, but the opening is wider. 



Zygoballus bettini Peckham. 



A larger and more slender species than terrestris. The body is 

 higher and narrower, the legs and palpi are larger, and the compli- 

 cated mandibles of the male are larger in proportion to their thick- 

 ness. The cephalothorax is almost as high in the middle as it is 

 wide, and slopes from the hinder eyes steeply backward. Toward 

 the front the slope is less, and the front of the head is half as high 

 as the hind pair of eyes. PI. XVII, fig. 4. The abdomen is rounded 

 above and widest across the hinder half. 



In life, the colors are bronze green and yellow, marked with white. 

 In alcohol the cephalothoi*ax is dark brown with whitish scales. The 

 abdomen is lighter brown, sometimes reddish, especially in speci- 

 mens not long preserved, with white markings sometimes forming a 

 regular herring-bone figure in the middle, and sometimes broken
