THE COMMON SPIDERS 



Clubiona than the other species. The color is the usual pale 

 yellow, a little brownish on the head and legs, and with two 

 longitudinal stripes on the cephalothorax. The abdomen is 

 nearly white, with two stripes made up of gray spots, and 

 scattered spots at the sides. The spots turn red in alcohol. 



Anyphaena saltabunda. — A pale short spi- 

 der, with long and slender legs (fig. 46). 

 The body is an eighth to a sixth of an inch 

 loner. The abdomen is oval, two-thirds as 

 wide as long, and nearly as high as it 

 is wide. The cephalothorax is three- 

 fourths as wide as long, widest across 

 the dorsal groove and narrowing grad- 

 ually to half as wide in front. The 

 eyes of the upper row are twice as 

 large as those of the front row. The 

 first legs are longest in both sexes, 

 measuring in the female over twice 

 the length of the body and in the 

 males three times. The spines are 

 very long on the legs and palpi but 

 only a little darker in color. The 

 general color is pale yellow or white, 

 with two broken gray stripes on the cepha- 

 lothorax and two middle and several lateral 

 rows of light gray spots on the abdomen. 

 The spinnerets are slender and two-jointed. The opening of 

 the air-tubes is halfway between the spinnerets and the 

 epigynum. The palpi of the male (fig. 47) are long and 

 slender, and the tibia is slightly curved and has a large thin 

 process on the outer side.
