The male, in life, is one of the most brilliant of our Attidse, 
the cephalothorax, including clypeus, being covered with iri¬ 
descent blue scales, and the abdomen, above and below, with 
iridescent pinkish-red. In alcohol, two white scallops appear 
behind the dorsal eyes, and the abdomen shows light bands at the 
base and sides and a fleur-de-lis mark in the middle, this being 
the pattern of the young male and of the female. Examples 
that have been kept in alcohol, when dried sometimes show this 
pattern in red on an iridescent bluish background. On the eye- 
region are erect black hairs. The legs and palpi are dark 
brown, the falces reddish with long white hairs on the inner 
edges. 
The female is variable. In the typical form the eye-region 
is mottled with short fawn and black hairs, with a darker 
transverse band between the dorsal eyes, behind which are 
two white scallops. The hairs behind, and on the upper sides 
are yellowish-brown, and those on the lower sides and clypeus are 
white. The abdomen is velvety black with a white band at base, 
a wide scalloped white band on each side behind the middle, 
and a central, irregular, white band which begins in front of the 
middle in a broad arrow head, and which may or may not reach 
the apex. At the end is a pair of white dots. The legs are 
medium brown. Another form has a white abdomen with a 
black band behind the base and four large black spots on the 
back.
