on the legs, plainest on the femora. The cephalothorax has distinct 

 light stripes along the sides, wider than in eastern specimens, PI. in, 

 fig. 4. The markings of the abdomen and the epigynum are as 

 usual. 



Lycosa albohastata, new sp. 



Two small male spiders are G'""" long, and brightly colored; the 

 cephalothorax is 3™™ long, and 2-5'^'" wide. It is brown at the sides, 

 with dark radiating lines between the legs, and this part is thinly 

 covered with orange-yellow hairs. The middle of the cephalothorax, 

 covering the head and narrowing backward to a point behind the 

 dorsal groove, is covered with light hairs, probably white or light 

 gray in life. The abdomen has a bright white spot in the middle 

 of the front half surrounded with black spots. At the sides the 

 abdomen is orange-yellow with a row of white spots each side, 

 toward the hinder end. In the middle of the hinder half is a row 

 of transverse black spots, in one specimen united with the dark 

 markings of the sides. PI. in, fig. 3. The legs are orange-yellow, 

 with indistinct rings, except on the femora, where the rings are 

 plain and deep black. 



On the under side the abdomen is dark at the ends and light 

 orange -brown in the middle, with a light line each side. The ster- 

 num, mandibles, and maxillae are very dark, and the coxae light; the 

 legs are lighter beneath. 



The male palpi are short and stout, the tarsus longer than tibia 

 and patella. The tibia is as wide as long. The palpal organ has 

 the middle hook very thin and twisted at the end. PI. ni, figs. 3a, 35. 



Two males from the valley near Laggan, and young females from 

 the neighboring mountains, 6000 or VOOO feet high.

Having the opportunity to examine a large number of specimens 

 from the White Mountains, Rocky Mts., and various parts of 

 Canada, as well as the types of Thorell's descriptions of the above 

 spiders from Colorado, I am convinced that they are all of one
