The web of Nicholasia pentagona is difficult to observe 
in minute detail because of the poorly lighted locations in 
which it is found. It is a small web, barely 1% inches in 
greatest diameter, and it is rather delicate. It is a hori- 
zontal orb-web, usually having four foundation lines and 
four radiating lines extending from a weakly defined hub. 
There are a varying number of spirals, usually less than a 
dozen. One foundation line connects terminally or centrally 
with a horizontal line outside of the web. The horizontal 
line extends between two walls of the shelter. From it 
hang two threads which become fused into a single thread,
