Family CLUBIONID.E (Clu-bi-on'i-dae). 



The Clubionids, or Tube Weavers in part. 



There may be found during summer, in flat tubular 

 nests on plants, usually in rolled leaves, spiders that spin 



no webs to entrap their prey. 

 These spiders very closely re- 

 semble the Drassids in structure, 

 but are usually lighter in color, 

 with the legs a little longer and 

 more slender, and the abdomen 

 more nearly cylindrical (Fig. 31). 

 —Maxilla of They are also distinguished by 

 the form of the maxillae, which 

 are convex (Fig. 32). These spiders belong to the family 

 Clubionidse. As we have no appropriate common name 

 for these spiders, they may be called the Clubionids (Clu-bi- 

 on'ids). 



During the winter the Clubionids hide under bark or 

 stones, and make tubular nests in these places.

Family AGALENID^: (Ag-a-len'i-dae). 

 The Funnel-web Weavers. 



Even the most careful observers seldom realize what an 

 immense number of spider-webs are spun upon the grass in 

 the fields. But occasionally these webs are made visible 

 in the early morning by the dew which has condensed upon 

 them. At such times we may see the grass covered by an 

 almost continuous carpet of silk. 



The greater number of the webs seen at such times are 

 of the form which we term funnel-webs. They consist of a 

 concave sheet of silk, with a funnel-shaped tube at one side,
