black bars, reaching the spinnerets. The white dots above the 
spinnerets are present. 
A male one moult from maturity has the cephalic plate cov¬ 
ered with fawn hairs, and whitish bands on the thoracic part- 
and sides, as above. The abdomen is black, marked with fawn 
basal, encircling, and transverse bands. The middle band on 
the front of the abdomen, which in the mature form connects the 
transverse and basal bands, does not reach the base, being only 
an elongated fawn spot, in front of, and touching the transverse 
band. Behind are three very small pure white chevrons and a 
pair of white dots. The clypeus is red. 
In the female the ground color of the whole body is dark gray 
the effect being produced by a thin covering of gray hairs on a 
black integu;ment. The cephalothorax has light gray dorsal and 
marginal bands, and the abdomen has light gray basal and trans¬ 
verse bands, the two heing connected by two light lines, instead 
of by a solid band. Just behind the transverse band are two 
fawn dots, and further back are four chevrons and two dots of 
the same color. On the posterior sides are several oblique gray 
bands. The hair on the clypeus and above the front eyes is 
fawn. 
We have several young females. At two moults from ma¬ 
turity the body is covered with fawn hairs, the clypeus and 
sides of cephalothorax are whitish, and there is a pair of white 
dots in front of the spinnerets. At one moult from maturity 
the body is gray rather than fawn, the abdomen has faint curved 
white bands crossing at, and behind the middle, and the two 
white dots are surrounded by black rings. One of our mature 
females retains this appearance. 
This is a northern species, corresponding to coronatus and 
calcaratus in the south. Mr. Banks has it from Franconia, 
Hew Hampshire; Mr. Emerton has found it in Massachusetts 
and at Long Island, Maine, and we have it from Hew York, 
Connecticut and Milwaukee, Wisconsin. 
It was Mr. Emerton who discovered that the young male of 
borealis has a red clypeus which disappears in the adult.*
