254. Dolomedes major, sp. nov. 



Plate XVII, Fig. 5. 



Length $ 24 mm.; ceph. 11 mm. long, broad 9 mm.; femur I 10 mm. 

 Cephalothorax yellow-brown, with a narrow yellow stripe each side, a pale 

 median line from the groove to the P. M. E., and often showing a curved 

 line behind the P. S. E. ; mandibles red brown; sternum pale, with brown 

 spots around the sides. Legs yellow-brown, darker toward the tips, without 

 bands; abdomen brown, rather blackish above, a pale indistinct basal spear- 

 mark and a submedian row each side of five white dots, and a short whitish 

 stripe on each posterior side. A. M. E. plainly larger than A. S. E. ; eyes of 

 posterior row about equal. Legs very stout; four pairs of spines under an- 

 terior tibia;. Abdomen rather high, once and two-thirds as long as broad. 

 The S is similar but smaller, 17 mm. long, especially the abdomen, and pro- 

 portionally longer legs; the hind femur has below at its apical third a promi- 

 nent stout spur tipped with many short black spines; the general color is 

 paler and the white dots surrounded by black. One 2 is almost black, but 

 does not differ structurally.
