The maxilla; are twice as long as the lip ; they are straight on the 
inner side above the lip, and excavated below for the sides of the lip ; 
they are truncated at the extremity ; in color they are white at the 
extremity and on the inner edge, and otherwise reddish. The lip is 
reddish tipped with white ; it is wider than long, and a little nar- 
rower toward the tip, which is slightly hollowed. 
The sternum is testaceous, darker than the thighs, with white hairs ; 
all the thighs are clothed with white hairs ; those of the anterior pair 
are separated by more than the width of the lip at the base. The 
sternum projects slightly beyond the anterior thighs. 
The relative length of the legs is 3, 4, 1, 2. The first and second 
pairs are a, little more robust than the third and fourth. They are dark, 
almost black in color, somewhat testaceous underneath. There are 
exinguinal, femoral, patellary, tibia! and metatarsal spines on the four 
pairs. 
The abdomen is bright iridescent red, lighter around the margin, 
and having a purplish tinge on the dorsum. There are four indented 
dots near the base, and sometimes a whitish basal band. 
The whole abdomen is covered with sparse black hairs, and the 
spinnerets are black. AVhen the spider is in alcohol the base anil a 
curved oblique band on each side appear red, and the dorsum dark iri- 
descent green, with a short longitudinal red band, narrowest in the 
middle. 
The venter is iridescent red, with two indistinct, darker, longitu- 
dinal bands.

The cephalothorax is not iridescent as in the male. The thoracic 
part has a black region at the base, from the anterior edge of which 
there comes off on each side a black band which curves forward and 
passes along the side of the cephalothorax below the dorsal and small 
median eyes, and reaches the anterior lateral eye. The black region 
at the base is usually limited in front, just posterior to the dorsal eyes, 
by a scalloped white or rufous band which curves forward in the 
middle. Anterior to this is sometimes another band, black, just be- 
tween the dorsal eyes. The eye-region is rufous, or, more rarely, black. 
Thesides of the cephalothorax below the black bands are covered with 
white hairs down to the lower narrow margin, which is black. The 
colors of the cephalothorax, particularly above, vary greatly between 
white, rufous and black. 
The dorsal eye is placed so much higher than the lateral eye that 
a straight line from its lower border passes above the lateral eye. The
