locations. Several individuals were kept and observed in an insect- 
ary at the Wau Ecology Institute (WEI). 
Uloborus albolineatus and U. bispiralis were found on the Gazelle 
Peninsula, East New Britain (ENB), Papua New Guinea. The webs 
of U. bispiralis were observed on the Lowlands Agricultural Experi- 
mental Station (LAES) at Kerevat, ca. 100m elevation, in cocoa 
plantations and in secondary growth lowland forest and near 
Malasat (ENB) at ca. 600m elevation. One web of U. albolineatus 
was observed at LAES in secondary-growth forest along a river. 
A single mature female of Uloborus #2072 (numbers refer to 
specimen numbers placed in vials) was found (by WGE) near Dan- 
deli, Karnataka, India, in the foliage of a bush growing in a teak 
forest. Uloborus trilineatus is common in undergrowth of gallery 
forest in eastern Colombia where WGE worked extensively. The 
webs described here were found at Finca Chenevo, about 20 km SW 
of El Porvenir, Meta, and Finca Mozambique, about 15 km SW of 
Puerto Lopez, Meta. Conifaber parvus was also found at Finca 
Mozambique (by WGE) where it occurred in periodically flooded 
forest but not in surrounding savanna. 
Webs were first dusted with cornstarch or talcum powder using 
either the method described by Eberhard (1977a) or Carico’s (1977) 
modification of this method, and then measured and photographed. 
All specimens mentioned in this paper are deposited in the Museum 
of Comparative Zoology. 
Observations 
Uloborus conus * 
The Web 
The web of U. conus has three parts: the inner orb, the rim, and 
the cone (Fig. 1). The inner orb and rim are in nearly the same plane 
and are more or less horizontal. The inner orb consists of a closed 
hub, radii and a few loops of non-sticky spiral, while the rim has 
several loops of sticky, cribellar spiral which end where the rim radii 
join those of the inner orb. Rim radii are continuous with those of 
the cone, and those of the inner orb are attached to them. Cone radii 
are attached in groups of two or three to a central guy thread which
