are strongly curved, tlie lateral much lower than the middle pairs, so 

 that the middle f I'ont eyes and the lateral hinder eyes form together 

 a nearly horizontal line. The thorax is marked by radiating grooves 

 between the legs. The abdomen is about twice as long as wide, 

 widest in the front half, a little truncated in front where it overlaps 

 the thorax, and tapering behind. The upper spinnerets are two or 

 three times as long as the under. The legs are long and tapering, 

 the fourth pair longest. The maxillae are much widened at the tips 

 and nearly straight on the front edges. 



The cephalothorax has two wide longitudinal dark stripes. The 

 abdomen has a light longitudinal stripe in the middle, straight in 

 front, and herringbone-shaped in the hinder half, generally a little 

 darkened in the middle and lightest at the edges. The sides of the 

 abdomen are dark, or covered with dark spots close together toward 

 the middle stripe and more scattered toward the sides. On the ven- 

 tral side the abdomen has a middle dark stripe, sometimes lighter in 

 the middle. 



Though the markings vary but little the colors vary from light 

 yellow, with pale gray markings, to dark reddish brown, with black 

 and gray spots, the colors being usually modified by long gray hairs 

 both in dark and light individuals. The joints of the legs are all 

 dark toward the end. Large individuals are, as a rule, darker col- 

 ored than small ones. 



The palpi are long in both sexes. In the males the femur is long, 

 the patella not much longer than wide, and without apjDcndages ; 

 the tibia about as long as patella, widened at the distal end, the 

 outer side extending forward along the edge of the tarsus and having 

 a short blunt tooth, figs. \c, \g, \d. The tarsus is large, the basal 

 half oval and the tip narrowed into a long point. The palpal 

 organ, especially the tube, which is largely developed in this species, 

 instead of having a constant form, as in most spiders, varies 

 extremely. The most common form is that shown in tigs, la, 1^, 

 with a stout flat tube coiled in one and a half turns under the tarsus, 

 and with the tip turned outward away from the tarsus. On the 

 outer side of the palpal organ near the end of the tube is a short 

 thin tooth with the outer edge turned downward and the corner 

 usually forming a blunt tooth directed toward the end of the palpus. 

 This variety is found in spiders of all sizes and shades of color from 

 all parts of the country. Among large spiders from various locali- 

 ties occurs the form of palpal organ shown in fig. \h. In this the 

 tube is much longer and more slender, and tei'minates in a sharp
