Bathyphantes nebulosa (Simd.) Thor., Syn. Eur. Spiders. 



Lepth'ijplumtes cryptkola Meuge. 



Plate XXII, figure 1. 



Perhaps Linyphia autumnalls lleiitz. Length 4""". Color liglit 

 brownish yellow with gray or blackish markings. Some specimens 

 are almost white, others are very dark with the black spots covering 

 a large part of the body. The cephalothorax has a forked dark 

 stripe along the middle and dark stripes near the edge on each side. 

 The abdomen lias six or seven pairs of irregular dark spots more or 

 less connected with a dark central line. The under side of the 

 abdomen and steinum have black spots which in dark individuals 

 are run together, making these parts entirely black. The legs 

 have dark rings on the ends and middle of the femoi-a and tibite. 

 The spines on the legs are long and darker yellow than the skin. 

 The epigynum is folded twice over the middle lobe of the end, with 

 its opening just visible beyond the outer fold. Fig. 2c. The palpal 

 organ is one of the most complicated in the family, though the parts 

 are folded together so closely that oidy the outer long appeiulage 

 with a toothed end and the tips of the inner parts are visible. 

 I have figured the palpus of this species, with the parts separated 

 by pressure, in the reprint of Hentz's Araneides of the United States, 

 under the name of Linyphia autumnalis Hentz. The tarsal hook is 

 large and complicated, and the tibia has a hard process grooved and 

 toothed at the end. (Fig. \d.) I liavo found this spider in cellars 

 and other damp and shady places about houses, with flat webs, under 

 which they stood near the edge or corner. I have compared several 

 European suecimens and believe this to be the same as Lepthypliantes 

 crypticola Menge. This species is perhaps imported.

Plate XXII, figure 2. 

 Length, 2""". Cej^halothorax bright yellow-brown, with indistinct 

 gray stripes in the middle and at the sides, and very black around 

 the eyes. The abdomen is crossed above by five or six gray and 

 whitish stripes, with scattered silvery white spots. Below, the thorax 

 and abdomen are both dark gray. All the parts of the palpal organ 

 are twisted across it. The tarsal hook has a very characteristic shape 

 too complicated to describe. Fig. 2. The epigynum is short and 

 wide, folded under except the tip. Fig. 2a. This is very near and 

 possibly identical with JB. zebrinus Menge.
