partly connected with a middle line (fig. 282). The head is 



wider and the eyes smaller and farther apart than in the other 



species, and the front middle eyes are 



the smallest. The head is wider in 



males (fig. 284) than in females, and 



the mandibles larger. It lives under 



stones and leaves at all seasons and 



occasionally on bushes. 



Steatoda corollata. — This, when full 



grown, is a little larger than marmo- 

 rata and darker colored, and the legs 



are shorter and stouter. The cephalo- 



thorax is dark brown, and the legs 



lighter brown, with dark rings at the 



ends of the joints. The abdomen is 



yellowish at the sides and has four or 



five irregular yellow spots, or pairs of spots, along the middle 



of a dark brown oval patch which nearly covers the middle of 



the back. In young specimens the abdomen is lighter, with 



several pairs of dark spots. The eyes 

 are all nearly the same size, the front 

 middle pair slightly larger and farther 

 forward than the others. It lives under 

 stones, like the other species. 



Steatoda triangulosa. — The female is a 

 fifth of an inch to a quarter of an inch 

 long. The legs are longer and more
