THE THERIDIDiE 



The Therididae are the builders of the loose and apparently 

 irregular webs in the upper corners of rooms, in fences and 

 among rocks, and between the leaves and branches of low trees 



Fig. 253. Webs of Theridium in a fog, on the tops of burnt bushes. Half the real size. 

 These webs are too fine to be noticed in dry weather.
