Descrijjtion. Pale gray, abdomen piceous, with various wind- 

 ing white marks, a middle one in the form of a cross ; feet with 

 piceous rings. 



Observations. This spider is well known even to those Avho 

 are not attentive observers of nature. Every one has noticed 

 its regular geometrical web, which is frequently placed near 

 the windows of our houses. It is subject to such variations in 

 color and marking that it is qiiite difficult to distinguish several 

 other species from varieties of this species. I have once found 

 seventeen varieties of spiders enclosed in the nest of a Sphex, 

 called dirt-dauber in the Southern States, and each could be 

 referred to this species, though they all differed more or less 

 from each other. This species seems domesticated, being sel- 

 dom found far from cur gardens. The reason probably is, that 

 it is more secure there from its enemy, the Sphex. 



Habitat. South Carolina.
