placed that a straight line from its lower border cuts the upper border 
of the lateral eye. The small median eye is on a line with the upper 
border of the dorsal eye, and is slightly nearer to it than to the lateral 
eye. The anterior row of eyes is very slightly curved, a line from the 
summit of the middle cutting the lateral eyes through their upper 
borders. The clypeus is about one-quarter as wide as the middle eyes, 
vertical, dark colored, with a few long white hairs. 
The palpus is pale, testaceous, with hair, light brownish, except at 
the extremity, where it is white. 
The falces are weak, vertical, short, light brown in color. 
The maxillae are narrow, and slightly inclined outward, rounded at 
tip. The lip is half as long, and rounded. 
The sternum is pointed behind and rounded in front. The anterior 
thighs are separated by less than the width of the lip at the base. 
The relative length of the legs is 4, 1,2,3. The first pair is the 
stoutest and darkest, and has the femoral joints flattened. The other 
legs are light brownish, testaceous with black hairs. There are 
femoral, tihial and metatarsal spifies on the four pairs. Those on the 
first pair are long and stout ; those on the third find fourth weak, and 
found only at the extremity of the metatarsi. 
The abdomen is blackish, with sparse yellow hairs. Four narrow 
lines of white hairs begin at the base ; the median two start from the 
same point, find separating a little, pass, one on each side of the 
middle, to the apex, terminating on either side of the spinnerets. The 
lateral lines extend along the sides from base to apex. They are not 
visible from above 
The venter is blackish, with short, sparse white hairs. 
The epigynum presents a wide heart-shaped plate, with the apex in 
front. The opening is large and on the posterior edge. The tubes 
may be distinctly seen through the skin.
