 varies very greatly m size, and is remarkably voracious.

 dew, myriads can be seen in April and May.

 PI. 12, fig. 2. 



Description. Pale rufous ; abdomen leaden color, with four 

 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 seen, 

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

 ferred to Herpyllus. 



Habitat. North Carolina, Alabama. [466.]
