Peckha'hi—Revision of the Attidce of North America. 523 
hairs, which indents a black, kidney-shaped region which occu¬ 
pies the middle part of th© dorsum. On this dark region are 
two round, snow-white spots, and further back, and more widely- 
separated, a second pair of smaller white spots. The part above 
th© spinnerets is grayish with a central white spot. The legs 
are brown, with the tarsi and metatarsi lighter than the rest. 
We have one specimen in which all the legs are light yellow with 
indistinct dark bands, and the thoracic part is yellow, while all 
the white bands and spots ^are distinctly accentuated. The pal¬ 
pus has the femur and patella light colored with white hairs, 
while the tibia and tarsus are dark. Our single female is badly 
rubbed, but seems to have been colored like th© male excepting 
that there are no white bands on the cephalothorax. The palpi 
are yellow with dark spots, and the legs yellow with black circles 
at the joints and longitudinal black lines on all the tibiae. The 
falces, in both sexes, are vertical and brown. The labium is as 
wide as long. 
We have one female and several males, sent to us by Prof. 
Wheeler, from Austin, Texas, and one male from Georgia. 
While in color and marking this species strongly resembles S. 
palustris and S. svlvestris, it is easily distinguished by the fact 
that in those spiders the fourth leg is very much longer than the 
others.

We have only two mature specimens, a male and a female,
