cross threads are attached to the hushes above the web. It 

 varies very greatly in size, and is remarkably voracious. 

 When very young it makes its web on the ground, on high- 

 ways; and in the morning, when the earth is covered with 

 dew, myriads can be seen in April and May. 



Habitat. Common in all parts of the United States.

2. Agelena? plumbea. 

 PI. 12, fig. 2. 



Description. Pale rufous ; abdomen leaden color, with fonr 

 impressed dots, the six nipples long ; same color beneath, one 

 pale spot each side of the base of the abdomen, over the pul- 

 monary orifices. 



Observations. This spider was found in North Carolina 

 under a stone, in a silken tube. Another specimen was also 

 found under a stone in Alabama; it was discovered watching a 

 cocoon made of thin but strong white silk, containing about 

 fifty or sixty eggs of a whitish color. As its web was not se/'ii, 

 it may not belong to this division, and may be ultimately re- 

 ferred to Herpyllus. 



Habitat. North Carolina, Alabama. [466.]
