nal bluish bands ; abdomen with two longitudinal bands of nu- 

 merous small red dots, the bands uniting towards the apex ; 

 feet, hairy, 4. 1. 2. 3. The sexes alike. 



Observations. This very active spider is often seen in mid- 

 winter on a mild day apparently migrating in great numbers, 

 being supported in the air by a long thread, and borne by the 

 breeze. Once^ many were seen in December, thus approach- 

 ing a large tree, under the bark of which they probably in- 

 tended to hibernate. A variety, perhaps a distinct species, was 

 found, destitute of dots or bands ; it was concealed in a silk 

 tube on a leaf. 



Habitat. North Carolina, Alabama.
