THE LYCOSID^E 



79 



the ends, and the femora faintly marked with light rings. In 



the middle of the cephalothorax there is a large light spot, 



widest just in front of the dorsal groove, and at the sides are 



rows of irregular light spots. On the abdomen are three or 



four pairs of light spots near together in 



the front half, and behind are two rows of 



spots meeting over the spinnerets. On the 



under side the color is a lighter gray than 



on the back. The color, as in all spiders, 



varies according to age, the young and freshly 



molted having a deeper black color, while 



older ones are gray. The epigynum is shown 



in the figure (fig. 1 88), and is quite constant 



in shape. It distinguishes this species from 



greenlandica (fig. 189), for which it is most 



likely to be mistaken. The male differs little 



from the female. This spider lives among 



gray stones in the hottest and driest places 



from Connecticut to Labrador. 



Pardosa albomaculata or greenlandica. — This 

 species resembles lapidicina (fig. 186), but is 

 a little larger and not quite as long legged. 

 It has longer hairs and is marked with bright 

 white spots on a black ground. There are 

 two rows of white spots on the abdomen, and 

 others along the sides of the cephalothorax 

 and on the legs (fig. 189). Wet in alcohol 

 it shows similar irregular markings on the 

 abdomen as lapidicina, but the light spots 

 on the thorax are smaller, the middle one extending forward 

 only to the dorsal groove. The epigynum (fig. 190) is large 

 and distinct. Its outline has been compared to that of a 

 decanter, narrow in front and rounded out at the sides behind.
