times as long as the cephalothorax. The first legs are about 

 seven times as long as the cephalothorax. The upper row of 

 eyes is a little curved, so that the lateral pairs of eyes are as far 

 apart as the middle ones (fig. 467). The general color is light 

 yellow. The abdomen is silvery white, with some indistinct 



gray markings along the 

 middle, and dark stripes on 

 the under side. In the males 

 the mandibles (fig. 467) are 

 short compared with the 

 other species, and are about 

 two-thirds as long as the 

 cephalothorax, and the tibia 

 is very little longer than the 

 patella. r ^ 



Tetragnatha straminea. — A 

 quarter to three-eighths of 

 an inch long, about the same 

 size as laboriosa, and the 

 same color. The legs, palpi, 

 and mandibles are all a little 

 longer than in laboriosa, 

 and the lateral eyes are 

 farther apart than the middle pairs (fig. 464). In the males 

 the abdomen is shorter and smaller, and the legs longer. The 

 male palpi (fig. 468) are one and a half times the length of 

 the cephalothorax. In females the abdomen is usually three 

 times as long as the cephalothorax and more slender than in 

 laboriosa.
