ground. The posterior sides are marked with two or three 
indistinct light bars. The legs are light brown with dark rings 
and inconspicuous white hairs. The femur and patella of the 
palpus are light yellow with thick snow-white hairs; the tibia 
and tarsus are dark with brown hairs, which grow long on the 
inner side of the tibia. The tarsus sometimes has a conspicuous 
white spot at the end. 
The female is clothed with reddish-brown hairs, and is marked 
like the male, but with less striking contrast of colors, the white 
being replaced by light brown. The palpi are reddish-yellow 
with white hairs. 
Mr. Emerton agrees with us that the form which he described 
as sylvestris is a variety of palustris, with the leg a little shorter 
and stouter. 
Mr. Banks reports palustris from Yew York (Long Island) 
and Colorado. We have it from Wisconsin and Yew York 
(Britcher Collection), and Mr. Emerton from Portland, Maine; 
Massachusetts; Connecticut; Ellis Bay, Anticosti; Lake Win- 
nepegosis; and Laggan, Alberta.

A red species. 
The integument is jet black, with a rather thin covering of 
bright red hairs, mingled with some silvery white hairs, which 
cover clypeus, legs, and two joints of the palpus, and appear also 
on the upper part of the falces. The eye-region has a growth of 
long upright black hairs, in front and on the sides. Farther
