New England. Tlie eggs are laid in Jidy. The young after leaving 

 the cocoon gather on the abdomen of the female which then looks as 

 large as a mouse. 



The palpal organ is small for so large a spider. The tube and the 

 supporting appendage are short and thin. The l)asal process is short 

 and black, slightly forked at the end. The epigynum resembles that 

 of pratensis and nidifex. 



Lycosa vulpina, uuw. 



Plate XLVII, figure 2. 



A large female measures 23""" long. Cephalothora.v, 12"'"' long, 

 9""" wide; 1st leg, 31"'"' ; 4th leg, 36'"'". 



The general color, in alcohol, is dark brown, with light gray or 

 white markings. The colors are all probably lighter in life. The 

 cephalothorax has a narrow light line in the middle, widest behind, 

 and wider and less distinct lines at the sides. The abdomen is indis- 

 tinctly figured with spots of dark brown on a lighter ground, or the 

 markings run together into a nearly uniform dark brown. The legs 

 are dark with light rings which are wider and more distinct on the 

 inner joints and absent on the tarsi and metatarsi. The sternum, 

 coxje and maxillje are all dark brown. The epigynum is shorter than 

 in carolineiisis and the end thicker. 



This species is about as large as L. carolinensls and has a general 

 resemblance to that species. It is easily distinguished by the rings 

 on tlie legs, the less distinct black nuirkings on the under side, and 

 the shape of the epigynum.

The cephalothorax is dark gray with a wide light band in the mid- 

 dle. The abdomen is light gray with a dark band in the middle, 

 which follows the shape of the dorsal vessel in front and incloses in 

 the hinder half 3 or 4 pairs of white spots. The legs increase in 

 thickness and the color becomes darker from the fourth to the first 

 pair. The first legs are dark brown covered with gray hairs, the 

 hind legs light gray or yellowish with black spines. The first and 

 second legs are black beneath except the tarsi. The sternum is dark
