316 AMERICAN SPIDERS AND THEIR SPINNINGWORK. 
medicinalis (or Durhami), whose web is so frequently found in cellars and 
shaded outhouses, the same fact meets us. There we see the thick sheet, 
not spread out broadly as in the case of Agalena, but rather pouched; thus 
forming a good receptacle for dropping insects, who are apt to roll easily 
into the little round open- 
ing at the apex of the 
snare. Above this open- 
ing is spun a short tubu- 
lar tower, which also is 
prolonged a little way be- 
neath the opening. With- 
in this peculiar structure 
the spider protects herself, 
precisely as in the case of 
the Orbweavers above de-

like leaves of a pine tree. 
If we pass next to the 
Saltigrades we find the same fact. The jumping spiders, whose bright 
forms and animated movements are familiar around our houses and 
yards, spin for their domicile thick white silken tubes, which 
differ very little in form and structure from those of the orb- 
weaving Furrow spider or the tubeweaving Drassid, Disdera, or 
Segestria. (Fig. 293.) 
The Lineweavers, although such close neighbors to the Orbweayers in 
structure, and having remarkable points of approach in certain features of 
the snare, are somewhat defective in points of architectural resemblance as 
far as the nesting tube is concerned. But they have some striking repre- 
sentatives of the prevailing type. There 
is, for example, the little lineweaving 
Theridium zelotypum which I have 
often observed along the trails in Adirondack for- 
ests, living in a little tent whose roof was the 
gathered leaves of a young pine tree, and whose 
interior was a silken tube or bell shaped dome 
quite resembling the nest of the Insular spider. 
Within this tent the mother Theridium domiciles, 
and with her dwell a number of her young. (See 
Fig. 294.) 
When the habits of American Lineweayers 
shall be studied more carefully, it will probably be found that Zelotypum 
is not alone in the matter of nidification. At least, we know that among 
the European Theridioids there are some species who almost equal the 
Epeiroids in the perfection of their nests. Theridium neryosum is one
