THE COMMON SPIDERS 



There is a long narrow middle lobe, generally widened at the 



end, but varying much in shape. At the front end of the epigy- 



num are two small depressions. It resembles the epigynum 



of glacialis (fig. 192), but is always longer and 



narrower and has the middle lobe straighter and 



more distinct. White Mountains, on bare 



stones. Rocky Mountains, Canada, and 



Greenland. 



Pardosa glacialis or brunnea. — One-third 

 of an inch long. Color dark brown with 

 some light markings. In the mid- 

 dle of the cephalothorax is a light 

 stripe, widening and fading out 

 toward the eyes and divided by a 

 dark middle line, widest in front 

 and extending back as far as the 

 dorsal groove (fig. 191). On each 

 side is a light stripe extending 

 under the eyes to the front of the 

 head. The abdomen has the mid- 

 dle pointed stripe light colored, and some- 

 times there are four or five pairs of small 

 spots of white hairs on the hinder half. In 

 alcohol there are obscure cross markings and 

 black spots. The legs are marked with longitu- 

 dinal dark and light lines. On the under side 

 there is usually a light middle stripe on the front of the sternum, 

 and the middle of the abdomen is lighter than the rest. The 

 whole body is hairy ; there are long black hairs on the front of 

 the head, and the spines are long and colored like the legs. The 

 epigynum (fig. 192) has a narrow middle lobe transparent at 

 the end so that it is difficult to see, and dark brown pieces 

 at the sides, with the outer ends turned forward. The shape
