along the surface of the rock, held away from it a short dis- 

 tance by threads fastened to projecting points on the stone 

 (figs. 239, 240). This species is sometimes mistaken for the 

 longer legged and more hairy Tcgcnaria 

 derJianiii (fig. 228), that makes similar 

 webs in barns and cellars. 



Tegenaria (Caelotes) longitarsus. — Smaller 

 than nicdicinalis ; about two-fifths of an 

 inch in length. The head is very wide, 

 and the mandibles of the female more 

 swelled in front than in nicdicinalis, and 

 the eyes are smaller and cover less than 

 half the width of the head (figs. 244, 

 245). The cephalothora.x is darker 

 colored in front and does not have the 

 two longitudinal stripes seen in mcdici- 

 nalis (fig. 241). The legs are only 

 faintly marked with gray in the middle 

 of the joints. The abdomen is marked 

 with gray, in a series of dark and light 

 spots, as in other species, and of more

epigynum is light colored, with a mid- 



rt, Agalena navia ; h, com- 

 mon form of Tegenaria der- 

 hamii, with the edge lower 

 than the tube ; c, Tegenaria, 

 with the edge higher than the 

 tube ; d, Tegenaria, with the 



die bar covered with hair and slightly 



forked at the hinder end (fig. 242). The 



male differs in the usual way from the 



edge carried up a long the face female and has the palpi shorter than 



of a rock ; c, Tegenaria, with 



the edge carried down as well mcdiciiialis. The tarsus has a projcc- 

 ^^"P" tion at the base that covers the tibia. 



The patella has a short process on the outer side that points 



directly forward (fig. 243). 



Tegenaria (Cicurina) complicata. — A small spider, resembling the 



young of the larger species of Tegenaria, found usually under
