The Irregular Snare. 



-The great majority of 

 British Spiders belong to 

 the family of the Theri- 

 diidae, or Line - weavers. 

 Some of these are among 

 the handsomest of our 

 native species, and are in 

 other respects highly in- 

 teresting, but their snares 

 lack the definiteness of 

 structure exhibited by the 

 orb -web, and little need 

 be said about them. 



For the most part they 

 consist of fine irregular 

 lines running in all direc- 

 tions between the twigs of bushes or among the steins of grass 

 and herbage. One large and important genus, /,//////<// in. ;\\ ways 

 constructs a horizontal sheet of irregular threads with a maze 

 of silk above it. Such snares may be seen in myriads in the 

 wayside hedges during the summer, and they are especially 

 notable objects when heavily laden with dew. Insects impeded 

 in their flight by the maze of threads drop into the underlying 

 sheet, and are soon completely entangled. The spider usualh 

 runs beneath the sheet in an inverted position. 



The sheet, or hammock of silk is absent in the ease of most, 

 of the other genera of this family, their snares being innocent of 

 any definite method in their structure. They are frequently 

 (piit.e. contiguous, and it is no uncommon thing to lind a hollv 

 bush completely covered with a continuous network of threads, 

 the work of a whole colony of the pretty little spider Tln-riil i<>n 

 sis// fill in in. 



As might be imagined from the simplicity or absence of 

 design in the structure of the net,, there appears to lie \ei\ little
