circle them. From the lateral edges of this band, on each side, an 
indistinct curved black band passes downward; and posterior to this, 
and parallel with it, is another black band. Extending from the apex 
to the posterior light spots, is a series of small black A s, which point 
forward. 
The venter is tawny, with a wide central gray band, not reaching 
the apex. Just at the apex is a short, traverse white band. 
The epigynum presents a plate which is rounded anteriorly, with 
the opening, as usual, at the posterior edge.

The cephalothorax is low; the thoracic part is longer than the 
cephalic. In color it is black, with its upper surface covered with 
brownish white hairs. The lower narrow margin is white. 
The quadrangle of the eyes is wider than long, and a little wider 
behind. The dorsal is about as large as the lateral eye, and is placed 
a little higher, so that its lower border is on a line with the middle of 
the lateral eye. The small median eye is on a line with the upper 
margin of the dorsal eye, and is equidistant from it and from the 
lateral eye. The anterior row is curved, a straight line from the top 
of the middle cutting the lateral eyes through the middle. The mid- 
dle eyes are touching, and are twice as large as the lateral eyes, which 
are more widely separated. The clypeus is less than one-fifth as wide 
as the middle eyes, and is deeply notched. It is covered with whitish 
hairs. 
The palpus has the tibia as wide as long, with a short curved apo- 
physis ; the tarsus is long. The bulb is simple. 
The falees are rather robust, and vertical. The fang is short. 
The maxi lice are short and rounded, brown in color. The lip is 
darker, half as long as the maxillse, also rounded. 
The sternum is twice as long as wide, dark brown. The anterior 
thighs are separated by the width of the lip at the base. 
The relative length of the legs is 4, 1,2, 8. The first pair is the 
stoutest, the second next. The femur of the first is reddish above, 
black beneath. The patella is reddish, and much more slender than 
the femur and tibia. The tibia is black, and is very stout. On the 
under side of these three joints is a thick fringe of brownish white
