outer side of the tibia, and four on the inner side, and three pairs 

 of spines on the metatarsus. In females these spines are long, more 

 than half the length of the tibia; in males they are short like the 

 spines of the other legs. The abdomen is oval, not much longer 

 than wide, resembling in shape as well as in markings that of 

 Amaurobius sylvestris. The lower spinnerets are wide apart, and 

 there is a wide opening to the tracheae between and in front. The 

 edge of the tracheal opening is thickened and colored on the inner 

 side so that it resembles a small cribellum. 



The colors are translucent white and gray. The legs are marked 

 with broken dark rings at the ends and middle of the joints. The 

 cephalothorax has a narrow black edge and broken radiating dark 

 marks like Ccclotcs mcdicinalis. The abdomen is marked with a 

 series of oblique light spots in pairs like Amaurobius. On the under 

 side the abdomen is light in the middle; the coxas are light, and 

 the sternum is light in the middle and dark at the sides. The light 

 color turns yellow by long keeping in alcohol. 



The male palpi have two processes on the tibia — one on the 

 upper side turned outward and sharp pointed, the other on the 

 outer side about half as long, stout, and directed forward. The 

 palpal organ is large, extending backward beyond the base of the 

 tarsus. The tube begins at the hinder end, extends around the 

 inner side and ends in the groove of a thick process on the 

 outer side.

A single female from Clarendon Hills maple swamp is 3 mm. 

 long, three-fourths the size of agilis. The proportions of the body, 

 the eye arrangement and the shape of the sternum and maxillse are 

 the same as in agilis. The opening of the trachea is midway 

 between the epigynum and spinnerets, not as far forward as in 

 agilis. The spinnerets are in a line, with the lateral pair slightly 

 larger than the others as in agilis, but the spinnerets are closer 

 together, the middle pair almost touching. The lateral spinnerets 

 are shorter than in agilis, being a third the length of the abdomen, 

 while in agilis they are half as long as the abdomen. The epigy- 

 num is shaped much as in agilis, but on each side there is a brown 

 loop under the skin that does not show in agilis. The color is 

 light brown, the legs without rings or markings. The cephalo-
