most exactly like that of clarus; the first leg, however, is rela¬ 
tively longer and has a much more conspicuous black and white 
fringe. The female is like the male, with black cephalothorax 
covered with inconspicuous gray hairs, and red abdomen marked 
with a black hand on the posterior two thirds. This hand is 
toothed with white or red on the edges. There is a white basal 
band, and the sides and venter are black. The black band on 
the abdomen has a line of green metallic scales down the middle, 
or, as Thorell describes it, is covered with these scales. Thorell 
does not mention the white basal hand, hut in other respects his 
description is excellent for our examples. 
The type came from Denver, Colorado. We have the species 
from Waycross, Ga., Baton Rouge, La., Texas, and Guadala¬ 
jara, Mexico. 
We give no figures of palpus and epigynum as these parts are 
almost identical with those of clarus.

The male has a black cephalothorax covered with inconspicu¬ 
ous brownish hairs. The abdomen may he black with red hands 
and spots, or may he uniform red, in which case the pattern 
shows in deeper spots of color when the spider is under alcohol. 
In the black form the red marks consist of a basal hand, an 
oblique hand on each side, a pair of spots directly behind the
