New Spiders from New England, XI. 



139 



The four white spots on the front of the abdomen are much 

 larger and closely united into a light spot covering the whole front 

 haK of the back, while the markings of the hinder half unite into 

 an equally conspicuous black spot. The dark markings of the 

 legs are blacker and more sharply defined. These peculiarities 

 are most evident in old females and least in males, which follow 

 more closely the usual markings of the species. Figs. 6, 6a, 6b.

Tetragnatha pinicola. new sp. 



This species resembles laboriosa, but is colored bright green with 

 white stripes at the sides, and a red spot at the front end of the 

 abdomen, sometimes continued as a red line on each side close to 

 the white stripes. Immature individuals found at various times 

 have been considered a green variety of T. lahoriosa, but several 

 adults, including one male, found on pines at l^antucket, in com- 

 pany with lahoriosa, show several differences beside the color. The 

 palpi of the male have the tibia half longer than the patella, and 

 the tarsus and palpal organ are larger than in lahoriosa. The legs 

 are also longer than those of lahoriosa, leg I being about one one- 

 sixth longer. This is true of females as well as males. The 

 arrangement of the eyes is as in lahoriosa, the lateral eyes being 

 perhaps a little closer together. Figs. 7, 7a. PI. I.
