rosy reflections, and the abdomen with greenish-golden scales. 
The legs and palpi are light brown, all the legs having two 
longitudinal lines of white hairs, throughout their length. Be¬ 
tween these, on the first leg, is a dark line. The falces and 
mouth parts are reddish-brown, the coxae pale, and the sternum 
and venter black. 
The appearance of this species is not especially ant-like. We 
have it from Guatemala and southern Texas, near the Mexican 
border. Cambridge reports it from Panama.

spines are so difficult to see that they are uncertain. The spider is easily 
identified by the red femora.
