The eephalothorax is high; the thoracic part is longer than the 
cephalic, and is a little dilated. In color the eephalothorax is black, 
covered with short brownish-yellow hairs; the lower margin is black; 
when the spider is in alcohol a light spot appears behind the dorsal 
eyes. The l'ovea is wide and shallow. 
The quadrangle of the eyes is wider than long, and slightly wider 
behind. The dorsal eye is a little smaller than the lateral, and is 
placed so much higher that a straight line from its lower border 
passes above the lateral eye. The small median eye is on a line with 
the lower border of the dorsal eye, but is nearer the lateral eye. The 
anterior row of eyes is slightly curved, a straight line from the top of 
the middle eyes cutting above the centre of the lateral eyes; the lateral 
eyes are placed further back on the face than the middle eves; the 
lateral eyes are half as large as the middle eyes, and are slightly sepa- 
rated from them, the middle eyes being also slightly separated. The 
clypeus is scarcely one-fifth as wide as the middle eyes, vertical, with 
a few brownish white hairs. 
The palpus is reddish, with white hairs; the patella is much longer 
than the tibia; the tibia has a curved, thorn-like apophysis. The tarsus 
and bulb are long. 
The falces are iridescent green, vertical, long and rather stout. 
The maxilla; are squarely truncated. The lip is pointed. 
The sternum is oval, black, with white hairs. 
The abdomen is covered with short, light yellow hair. There is a 
white band at the base ; the centre of the dorsum has a wide, longi- 
tudinal black band, which has some brownish hairs down its middle 
line; the black on either side of these hairs is interrupted in three 
places by spots of yellow hair, the two anterior spots being at about 
the middle point of the dorsum, and the four posterior much nearer 
the apex. There are two white, oblique bands on each side. 
Habitat, Pennsylvania. 
Observations. This species resembles A. sinister of Hentz, but 
differs from it in the relative length of the' legs, and in having much 
yellow, and no rufous, on the abdomen.
