Attklcc of North America. 19 



peus covered with white ]iairs; sternum, coxae and mouthparts black; 

 falces black with some white hairs on the anterior surface; palpi and 

 legs yellowish, excepting the femur I which is black above and pale 

 beneath; third and fom'th pairs darker than first and second, and 

 showing some reddish rings on patella and tibia. All the legs have, 

 on the under side, long, fine, yellow hair, which is strikingly long and 

 thick on the first pair. 

 The abundance of fine yellowish hairs on the undersides of the first pair 

 of legs, together with the great distance between the anterior lateral and 

 large middle eyes distinguishes it from all other species of this genus. 

 Habitat: Arizona, Texas, California.

 brown hairs; usually there may be distinguished two or three oblique 

 white bands extending downward over the sides. The pattern on the
