lata. In New England tliis species continues to be rare, but in the 

 Kocky Mountains and in Oregon and California it is common on 

 fences and outside of houses. On the piazza of hotels through the 

 Canadian Rocky Mountains, the males vary in size from that of 

 soli/ana with the cephalothorax 5 mm. in length, to the smallest 

 silvatica only 3.5 mm. The length of the first femur varies in these 

 specimens from 5.5 to 4 mm. Four males from the hotel at Glacier 

 varied among themselves nearly as much. The palpi of the larger 

 specimens resemble solitaria and nigra, with the tube curved up- 

 ward at the base and strongly curved toward the end, while in 

 smaller, light-colored individuals, the tube is less curved, lies closer 

 to the bulb and tapers more regularly toward the point, as in the 

 smaller silvatica. The shape of the second tibia is the same in all 

 the varieties, the spines being somewhat longer and stouter in larger 

 individuals. 



The females vary but little, except in color, most of the western 

 specimens being darker than those from New England. The shape 

 of the epigynum is very uniform, with the finger very long and 

 slender. 



In August, 1906, Mrs. Annie Trumbull Slosson found a male on 

 the hotel at the summit of Mt. Washington that resembles very 

 closely the original E. solitaria from Massachusetts. 



Epeira corticaria, Em. New Engl. Epeiridse, 1884. (Plate V, 

 figures 3, 3a.) 

 Mature males and females are found on the lower part of Mt. 

 Washington, N. H., in the early part of August. The females have 

 the finger of the epigynum broken off or shrivelled. The males 

 are marked and colored like the females, except that in the males 

 the dark stripes at the sides of the cephalothorax are wider, and 

 the dark rings of the legs more distinct. The second tibiae are 

 slightly thickened and curved, and five spines on the upper side 

 and two on the inner side are thickened and dark-colored. There 

 are no spines on the coxae. 



Epeira Nordmanni, Thorell. 



A male from The Glen at the base of Mt. Washington, N. H. is 

 9 mm. long, the cephalothorax 5 mm. The dark stripes at the 

 sides of the cephalothorax are wider and more definite than in the 

 female. The markings of the abdomen are like those of the female, 

 but are less distinct. The second tibiae are slightly thickened and
