the band of shining white scales on the palpus of clarus. Along 
the sides of the tarsus are long black hairs. The legs are banded 
with light and dark red, the femora being darker than the other 
joints. The front legs are covered with short and long white 
hairs, the latter forming a. fringe which varies considerably in 
length and thickness, being sometimes as striking as in the 
male of insignarius. The falces are sometimes metallic green, 
sometimes dark red with scarcely any iridescence. The clypeus 
is covered with yellowish white hairs. The black region over the 
eyes distinguishes this spider from McCookii and cardinalis, 
the only other males with a red cephalothorax unmarked by 
black or white bands. 
The female is like the male except that a light band comes up 
from between the front middle eyes, nearly crossing the black 
hairless region. The venter is black with two light bands, con¬ 
verging towards the spinnerets. 
We formerly called this species rufus H., but this was plainly 
a mistake, and we now think that it is impossible to know what 
Hentz meant by his description of rufus, and we therefore name 
it Whitmanii, for Prof. C. O. Whitman, of the University of 
Chicago. 
We have males from Boston, Ithaca, H. Y., and Milwaukee, 
Wis., and Mr. Banks has them from Franconia, 1ST. H., and 
East Falls Church, Va. Females have been taken by Mr. Em- 
erton, in Boston, and at Waltham, Mass. 
$ . Moult before maturity. Black cephalic region cut in two 
by light band which comes up from between middle eyes. Be¬ 
tween dorsal eyes a large bright red spot, much brighter than 
abdomen, bordered by yellow, which is brightest in front. Hind 
thoracic part and sides black with a thin whitish pubescence. 
Abdomen red with very bright white basal and side bands and 
three pairs of spots all bordered by deep black.
