Family CLUBIONID/E (Clu-bi-on'i-dae). 
The Clubtonids, 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).

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^E (Ag-a-len'i-dae). 
The Fu fin el-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 ;
