yellow an<l is crossed by a great number of black transverse lines, 

 three on each segment, which are sometimes obscured, especially in 

 yonng spiders, by a thick covering of silvery white hairs. The 

 cephalothorax is covered with white hairs through which the dark 

 markings on the sides of the thorax shoAV indistinctly. The legs are 

 light yellow with black bands around the ends and middle of each 

 joint. The femora of the first legs are sometimes entirely black. 

 The epigynum is uncovered, showing two openings separated by a 

 slight ridge. The colors and markings under the body are like those 

 of A. riparia. The young of this species have the back entirely 

 white until nearly full grown. 



The male is about 5'""* long. The legs and cephalothorax are 

 yellowish and the abdomen white. The markings underneath are 

 similar to those of the female but paler. The legs are yellowish, 

 mai'ked with black spots but no rings. The cephalothorax is rather 

 wider than in the male of riparia and does not have the dark mai'ks 

 along the sides. The palpi are very different from those of riparia. 

 The tube is coiled once around the end of the bulb, the tip turned 

 slightly outward. It is accompanied by two hard appendages, as in 

 riparia, but these are shorter and somewhat twisted with the tube. 



This has the same habits as riparia, and is found with it in the 

 same bushes. It remains in its webs rather later in the fall than the 

 other species. The cocoons are flat on top, not narrowed into a stem. 



I have females from the Adirondack Mountains, collected by F. A. 

 Bowditch, and from Ottawa, Canada, J. B. Tyrrell. In Eastern 

 Massachusetts it is very common, especially near the sea-shore. 

 Near New Haven, Conn., it is found with riparia but neither is 

 common. It extends southward probably as far as Florida. 



This species was called Epeira fasciata by Hentz, who supposed 

 that it might be identical with the Epeira fasciata or hruennichii of 

 Europe. The differences in the epigynum and male palpi are 

 enough to separate the two species. In hruennichii the epigynum is 

 covered by a process directed backward as in rip)aria, while in trans- 

 versa, the two openings are uncovered. The males of hruennichii are 

 proportionately larger than those of transversa and have more distinct 

 markings on the abdomen and thorax. The tube of the palpal organ 

 is less twisted than in transversa. 



Argyroepeira, new. 



These spiders have long slender legs like Tetragnatha. The abdo- 

 men is lonsx and round but often thicker in the middle and never as
