tips and widest half way to the base of the palpus. Fig. 2a. The 

 labium is long and widened at the base. The sternum is widest in 

 the middle, narrowed behind, and truncated at the front end. The 

 coxae are very long, fig. 2«. The first legs are longest and the fourth 

 next. The feet have only two claws and under them a thick brush of 

 flattened hairs. Fig. 'ib. The patellne are only about a fourth shorter 

 than the tibiae. The abdomen is long, oval and a little pointed behind. 

 The cephalothorax and mandibles are reddish-brown. The legs are 

 lighter colored and more yellow and become a little darker from behind 

 forward. The abdomen is dirty white or yellow without markings. 



The male differs little from the female. The palpal organ is as 

 long as patella and tibia of the palpus. The terminal half is a 

 little curved inward, and on the outer side is a short blunt tooth a 

 little curved upward. Figs. 2c, 2d. 



Swampscott, Brookline, and Roxbury, Massachusetts. This is the 

 only Dysdera I have seen from New England, and as Hentz's D. 

 mterrita came from Massachusetts, this is probably the species. It 

 agrees very closely with D. crocata Koch = D. ruMcunda Blk. 

 The palpal organ of D. mterrita is straighter, as seen from in front, 

 than that of crocata.

Female 9™"' to 10"^™ long. Plate viii, fig, 3. Cephalothorax long 

 and narrow, widest opposite the third pair of legs. Jn the male the 

 cephalothorax is proportionally much wider. The dorsal groove is 

 very small, and the head is not separated very distinctly from the 

 thorax. The abdomen is oval, widest across the middle. The first, 

 second, and third pairs of legs are turned forward. The first pair is 

 longest, the second next. The legs are all stout and the first and 

 fourth pairs have the patella and tibia much thickened. The color of 

 the cephalothorax and legs is darker from behind forward, the fourth 

 legs being light yellow and the first legs and front of the head dark 

 brown. The abdomen is pale at the sides and dark purplish-brown 

 above and below, darkest along the middle of the back. 



The feet have three claws, fig. 8c?. The tibia and metatarsus of 

 the first and second legs have two rows of strong spines on the under 

 side, four pairs on the tibia and eight or ten pairs on the metatarsus. 

 The sternum is long and widest in the hinder half. The maxilla? are
