cephalothorax. Sternum nearly round, truncated. Coxae I 
widely separated. Labium a little longer than wide. Clypeus 
high. Legs all long, more or less fringed. Spines well developed. 
Falx with one tooth on lower edge. 
We distinguish this genus from Corythalia by the rounded 
shape of the cephalothorax, the rounded sternum and the straight 
front row of eyes.

The color of the cephalothorax varies from dark brown to 
black. The cephalic part is iridescent, and seems to have been 
covered with white scales, although these are nearly all rubbed 
away in our examples. There are white bands on the lower 
sides, and on the middle of the thoracic part is a white spot, from 
which, in some specimens, two divergent white lines run to the 
dorsal eyes. The abdomen is brown with a deep black band 
around the anterior end, and behind this a white band, widest 
in the middle, and with its posterior edge indented. The male 
has, on the front part of the dorsum, two or three pairs of white 
spots or bars, which sometimes join to form lines. On the pos¬ 
terior half are alternating white and dark chevrons. The fe¬ 
male has the same pattern a little more accentuated, the band
