Length, 3 $ 5-7 mm. Legs, 3 ? 4132, equally stout. 
Cephalothorax rather high; thoracic part on a lower plane 
than cephalic, with a slight constriction in front of the middle. 
Sides nearly parallel, contracting a little behind. Quadrangle 
of eyes very slightly wider than long, a little wider behind than 
in front, occupying two-fifths of the cephalothorax. Anterior 
eyes in a straight row, all somewhat separated from each other, 
the lateral about one-half as large as the middle. Second row 
about half-way between first and third rows. Third row not 
quite so wide as cephalothorax at that place. Ealces (S) wider 
than first row of eyes, more than three times as long as face, 
nearly horizontal, diverging; fang as long as falx; (?) much 
weaker and shorter, slightly inclined forward, fang short. On 
the lower margin of the falx is a single tooth. Lip about as 
wide as long. Coxse I separated by more than the width of the 
lip. Sternum long and narrow. Abdomen constricted in front 
of middle. Legs all slender with three pairs of spines under 
the tibisB, and two pairs under the metatarsi, of the first and 
second pairs. 
The cephalothorax is yellowish-brown with an indistinct light 
mark across the middle. The abdomen has, at the constriction, 
a white band, which slopes backward along the sides and nearly 
to the spinnerets. In front of the constriction it is brown, and 
behind it, black. We have seen only specimens in alcohol. Mr. 
Emerton, who is familiar with it in life, says that in color and 
general appearance, it resembles orange-brown ants, the colors 
being various shades of orange-brown, some individuals very 
dark, others pale. The legs are yellow with the tarsi of the 
first pair dark, and the first and second with a more or less 
distinct dark line in front. The palpi are darker than the legs, 
and, in both sexes, have the tibia and tarsus very much thick¬ 
ened, and covered with stiff hairs on the under side. 
Mr. Emerton has this species from Massachusetts and Connec¬ 
ticut, and Mr. Banks from ISTew York, Louisiana and Elorida. 
Koch reports it from Pennsylvania, and in our collection are ex¬ 
amples from KeW York, Missouri, Mississippi and Texas.
