THE DliASSIDyE

°o00o'' 



Agroeca pratensis. — A little light-colored spicier, resembling 

 the next species, AnypJicBua incerta. It is about a fifth of an inch 

 long. The cephalothorax is wide behind and low in front and 

 highest near the dorsal groove. The head is contracted in 

 front of the legs more than it is in 

 incerta. The front row of eyes is 

 nearly straight, the middle pair only ^3 



a little the higher (fig. 33). The upper row 

 is longer and more curved, with all the eyes 

 about the same distance apart, the middle 

 pair not so much separated as in incerta. 

 The abdomen is widest behind, but not as 

 wide as in incej'ta. The spinnerets are two- 

 jointed, as in Anyphaena. The legs are long, 

 the fourth pair longest, and are a little thicker 

 than those of incerta. The coxae of the hind 

 legs almost touch, and the sternum is short 

 and nearly round (fig. 36). The labium is 

 short and the maxillae straight, as in Any- 

 phaena. The cephalothorax, legs, and mouth 

 parts are light brownish yellow. The cephalo- 

 thorax has a fine dark line on each side and 

 two broken longitudinal stripes made up of 

 gray marks radiating from the dorsal groove. 

 The abdomen has two rows of gray oblique 

 markings on a light ground. The general 

 appearance is like a small Lycosa. It lives 

 among leaves and short grass. There is 

 little difference between male and female. 



Anyphaena incerta. — About a fifth of an inch long, light yellow, 

 with gray markings. The cephalothorax is three-quarters as 

 wide as long, rounded at the sides and highest in the middle. 

 The front of the head is very low, so that the eyes nearly.
