and shorter and stouter tlian in the other species. The abdomen is 

 long-oval, light yellow above, with dark brown markings which 

 sometimes nearly cover it. The under side of the abdomen and 

 sternum are dark brown. The epigynum has a large opening in the 

 middle. Fig. 3cZ. The palpal organ has a spiral spine at the end 

 crossed by radiating lines. A large triangular appendage near the 

 base shuts over the others. Figs. 3(?>, 3c. The tarsal hook is-very 

 small and slender. I have only a few specimens of this spider. The 

 web is Hat and near the ground. The spider stands at one side like 

 L. Phrygian a. 



Eastern Massachusetts. I have compared the American specimens 

 with a few European clathrata and believe they are the same.

Length, 5'"™. Cephalothorax light yellow, with a black line in the 

 middle forked at the forward end, and a black line each side on the 

 edge of the thorax. Legs light yellow, with a dark I'ing on the end 

 of each joint and the middle of each tibia and metatarsus. The legs 

 have also many dark spots, especially on the femora. The spines of 

 the legs are black and conspicuous. The abdomen is yellowish with 

 brown spots at the sides and beneath, and a dark brown or reddish 

 herring-bone stripe along the middle of the back. The head of the 

 male is twice as high as that of the female, and has a cluster of stiff 

 hairs on the top. The male palpi have a long spur on the patella. 

 The tarsal hook is longer than in the neighboring species but thin 

 and sickle-shaped. The palpal organ itself is small and resembles 

 that of cotnmimis. Fig. le. The epigynum has two openings 

 partly covered by a triangular lobe, which extends backward over 

 the middle of the epigynum.* Fig. 1/*. 



This is a very common species, both in town and country. It 

 builds in fences and low bushes a large flat web, and stands concealed 

 under one corner of it, running out quickly if anything touches it.

 States and Europe.
