transverse lines, and the dots of the posterior pair are sometimes united, 
forming one spot. On the sides are live oblique pale bars. 
The venter is reddish, or brownish, with a central darker band, and 
is covered with short white hairs. 
The epigynum presents a plate wider anteriorly, with a rounded 
opening at the posterior edge.

The cephalothorax is rather high ; the cephalic part is shorter than 
the thoracic, and slants a little toward the anterior eyes ; the anterior 
part of the thoracic region is prominent ; the posterior part slopes 
abruptly to the base. The fovea is deep. The whole cephalothorax is 
covered with dark, but highly iridescent scales, which have red, blue 
and green reflections. If the specimen is looked at in alcohol, two 
whitish testaceous spots appear just behind the dorsal eyes. The lower 
narrow margin is black. On the anterior part of the eye-region are 
some upright black hairs. 
The quadrangle of the eyes is wider than long, and wider behind- 
The dorsal eye is about as large as the lateral, and is placed higher, 
so that a line from its lower border cuts the upper border of the lateral 
eye. The small median eye is in a line with the middle of the dorsal eye, 
and is equidistant from the dorsal and lateral eyes. The anterior row 
of eyes is straight. The middle eyes are slightly separated ; the lateral 
eyes are separated from the middle eyes by about one-third their di- 
ameter. The middle are more than twice as large as the lateral eyes. 
The clypeus is nearly as wide as the middle eyes. It is inclined back- 
ward, and is darkly iridescent. 
The palpus has the tarsus long and oval ; the tibia is shorter and 
narrower than the patella, is wider than long, and has a very strong, 
short aphophysis, two-thirds as wide as long, which follows, and lies 
close to the side of the tarsus ; the patella is as wide ;es long, and a 
little wider at the distal end ; the femur is as long as the patella and 
tibia, including the apophysis, and has two strong spines. 
The falces are not robust, vertical, scarcely as long as the face ; 
they are dark reddish brown, with long white hairs on their inner 
edges.
