rupted anteriorly (on the anterior aspect of the abdomen the black 

 band of one side joins with that of the other), while posteriorly the 

 black band widens and becomes mottled with buff; sides buff, spotted 

 with black posteriorly; venter yellow in front of the lung-books, 

 behind them pale brown with small spots of darker l^rown and black. 

 In other individuals the dorsum shows the same general pattern, but 

 the silvery-white is replaced by yellow and the black by browm. 

 Epigynum reddish-brown. Spinnerets pale brown. Chelicera brown 

 or almost black, the macula red. Lahium as dark as the chelicera but 

 with lighter distal end, and maxillce lighter. Legs in the brightest indi- 

 viduals clear greenish-yellow, distinctly ringed with black on all the 

 joints except the tarsi, each coxa black on its anterior and posterior 

 aspects, the tarsi reddish-brown. Palpi colored like the legs. 



Comparisons.— This species comes very close to sublata, but differs 

 from it in the coloration of the cephalothorax and of the abdominal 

 venter. The epigyna of the two are very similar. 



Habits. — Not common, on damp ground under stones, on the margin 

 of streams. 



Troohosa pratensis (Emerton). 



Lycosa pratensis Emerton, 1885. 



Lycosa pratensis Emerton, Montgomery, 1903. 



(99 from Wood's Hole, Massachusetts.) 



Eyes. — First row a little broader than the second, the middle eyes 

 larger and slightly lower, lateral eyes nearer the second row than to 

 the clypeal margin. Eyes of second row largest, their diameter apart. 

 Length of dorsal eye area to cephalothorax as 1 : 6.5. 



Form. — Cephalothorax highest between the posterior eyes and the 

 dorsal groove, in front truncated and a little more than one-half its 

 greatest transverse diameter, sides of head obliciue. Chelicera longer 

 than the width of the clypeus, 2.5 times the height of the head in front. 

 Labium longer than wide, its sides nearly parallel, truncated apically, 

 one-half the length of the maxillae. Sternum longer than broad. 

 Spinnerets equal. Legs thick, leg IV to cephalothorax as 2.7 : 1 ; meta- 

 tarsus IV shorter than the patella and tibia combined. Palpal claw 

 with 5 teeth. 



Troohosa contestata (Montg.). 



Lycosa contestata Montg., 1903. 



( 9 from Wood's Hole, Massachusetts.) 



Eyes. — First row slightly shorter than the second, much nearer the 

 clypeal margin than to the second row, middle eyes double the size of 

 the lateral and a little higher. Eyes of the second row nearly L5 times
