$Tegenaria derhamii.$--This is a common species in barns and cellars, and has probably been imported from Europe, where it is even more common. The head is high and wide, as in _T. medicinalis_. The mandibles are less swelled in front and the eyes are closer together than in that species, and cover more than half the width of the head (fig. 229). The cephalothorax is shorter and wider across the hinder half and the abdomen shorter than in _medicinalis_, and the legs are longer and more hairy. The colors are lighter and the hairs of the whole body longer. The female is two-fifths of an inch long. The cephalothorax is pale, with two gray stripes. The abdomen is marked with a series of gray spots, formed of a middle row more or less connected with two side rows; the front of the abdomen often pale, with the markings faint (fig. 228). The legs are long, the first and fourth pairs nearly twice the length of the body. They are marked with faint gray rings at the ends and two in the middle of each joint. The palpi are long and slender in both sexes, and those of the male have the patella and tibia of about the same length and each nearly twice as long as wide. There are no processes on the patella, but two small teeth on the tibia near its end. The tarsus is small and narrow, not as long as the patella and tibia. [Illustration: FIG. 230. Web of Tegenaria derhamii in corner of cellar.] [Illustration: FIG. 231. Web of Tegenaria derhamii with spider in mouth of tube. Old cocoons hanging at the left.] [Illustration: FIG. 232. Web of Tegenaria derhamii curving downward on each side.] The webs are made in all parts of cellars and unswept buildings, sometimes forming a shelf in the corner, not as large or as flat as those of _A. nævia_, but with a similar tube on the most sheltered side (fig. 230) The webs more often spread under beams and floors fastened up by threads at the sides and edges, and, as they gather dust, hang down by its weight and become torn and tangled. Old webs are repaired and extended until they become as thick as cloth with silk and dirt. The tube is generally smaller and less funnel shaped where it enters the web than that of Agalena. The web is not as flat as that of Agalena, curving usually down from the tube and up in front of it, often turning up abruptly at the edge. Sometimes it is fastened up in the middle of the front edge and curves downward each side (fig. 232). Fig. 231 shows a web of the most common form in the corner of a cellar, with the spider standing at the mouth of the tube, and the remains of egg cocoons hung up at the left. This web was at least a year old, and the front edge had just been extended with clear and transparent silk, while the middle was black with coal dust. Fig. 232 is another web in the same cellar, with the front edge fastened up to the boards above. It is drawn tightest in the middle and curves down on each side.
