The male has the cephalothorax black with green iridescent 
scales on the cephalic plate. There is a narrow band of white 
scales on each side extending from the anterior lateral eye as 
far back as the posterior margin. The abdomen is red-brown 
above covered with green, golden, and pink scales. There is a 
white basal band reaching nearly to the spinnerets where it is 
continued as a spot. Sometimes this band is broken up into 
several elongated spots after the first half. The hack has a 
row of three white spots on each side; the last pair are often 
elongated and transverse. All the spots and markings are made 
up of white scales. The falces are inclined forward and diver¬ 
gent with dull green reflections. The legs are black or brown 
covered with black hairs, except at the base of the patella of the 
first, when the hairs are white. The tarsi and metatarsi of the 
posterior three pairs yellow. Under side of the body brown to 
yellow in different specimens. The palpi are brown without 
white on upper side. In some specimens the tarsus and meta¬ 
tarsus of the first leg are yellow. Indeed the depth of color of 
these joints varies greatly. 
While the coloration is variable in the male, in the female it is 
much more so. The top of the cephalothorax is covered with
