slender, abbreviated, black and brownish lines, underneath 

 whitish, with a longitudinal blank band ; feet with very long 

 hairs or bristles.

 extremely active, leaping like an Attus. It is rather rare, but 

 very distinct from any other. 



Habitat. North Carolina, Alabama.

Habitat. Alabama. September.
