length, 36 mm. The palpi are mm. long with the tibia straight 

 and with a forked process in the middle of the outer side. The 

 tarsus and palpal organ have been correctly figured in N. E. Lycosida?. 

 This species seems to be common as far south as the mountains 

 of North Carolina. On Lake Champlain, Vt, and Lake Winnipesaukec, 

 N. H., it matures about July 1, when it is common along the shore 

 under loose stones and the floats of boat landings. It runs on the 

 surface of the water and on the bottom, carrying a large amount of air 

 adhering to its hairs. It remains under only a short time, coming 

 quickly to the shore as soon as it has escaped pursuit. 



Dolornedes idoneus, Montgomery. Proc. Phila. Acad. Nat. Sci., 

 Nov. 1902. (Plate VII, figure 8.) 



The female of this species is of the same size as fontanus and 

 has similar markings, but the color in alcohol is reddish brown in- 

 stead of olive gray, which is usual in fontanus. The shape of the 

 head is the same as in fontanus, and the arrangement of the eyes 

 is the same, the only difference being in the size of the front middle 

 eyes, which in this species are twice as large as the laterals of the 

 same row. The shape of the epigynum is characteristic of this 

 species, even when half grown. The middle lobe is round and 

 swells out beyond the surface of the abdomen, and there is a distinct 

 opening on each side between it and the lateral lobes. 



The male has not been described. 



Females have been found at Lake Champlain, Vt., and at Sims- 

 bury and New Haven, Conn. 



Dolornedes urinator, Hentz. Montgomery, Proc. Acad. Nat. Sci., 

 Philadelphia, 1904. 



The male spider described by me in 1885 as the male of D. 

 tenebrosns appears to be urinator or lanceolatns, Hentz. I have not 

 found females but have one from Pennsylvania sent me by Mr. 

 Montgomery. 



An immature male from Milton, Mass., resembles closely the draw- 

 ing of D. lanceolatns by Hentz. It has the tuft of stiff hairs on 

 the femur of the fourth leg, like the mature males that I have de- 

 scribed. 



Dolornedes vernalis, new. (Plate VII, figures 7 to 7d.) 



Males from Falmouth, Me., and Three Mile Island, Lake Winni- 

 pesaukee, N. H. Cephalothorax 3 to 4 mm. in length and a little 

 less in width. Fourth and first legs 16 to 18 mm. The colors are
