the bulb, then passes through the usual groove to the outside of the 

 tarsus, where it is coiled once around the flattened end. Fig. be. 



This species lives on plants and matures early in the summer. At 

 first sight it resembles an ant, but its gait is slower and steadier. I 

 have never seen it jump but it runs quickly when frightened. It lives 

 in summer on bushes, and matures in June. In the latter part of 

 summer only young are to be found, and in the winter it hides under 

 leaves on the ground. 



Common at New Haven, Conn., and around Boston, Mass.

This spider is 7'""' long, the cephalothorax 3™'" long, and half as 

 wide. In color and general appearance it resembles orange-brown 

 ants. The cephalothorax is high in front and low behind the dorsal 

 groove, which is in a slight depression. PI. XXI, fig. 4a. The sides 

 of the cephalothorax are nearly straight for two-thirds its length, and 

 it is only slightly narrowed behind. The abdomen is oval, a little 

 narrower in front than behind. The legs are long and slender, their 

 length 4, 1, 3, 2. Fig. 4. 



The colors are various shades of orange-brown, some individuals 

 being very dark, and others pale. There is an indistinct light mark 

 across the middle of the cephalothorax and across the abdomen, a 

 little in front of the middle, and sloping backward down the sides 

 nearly to the spinnerets. 



The femoi-a of all the legs are dark, except a light stripe on the 

 front of those of the first pair. The patella and tibiae are all light 

 on the upper side and darker beneath. The metatarsi of the hind 

 legs are dark, the others partly light in the middle, or on the iipper 

 side. The tarsi of the front legs are dark, the others light. The 

 coxae of the third legs are dark, the others light. The palpi of the 

 female have the tibia and tarsus very much thickened and covered 

 with stiff hairs on the under side. The palpi are colored as dark as 

 the head. The epigynum has two small openings near together, and 

 turned toward each other. Fig. 4e.
