September until frost their webs became more and more 
conspicuous. They made funnel-shaped webs, with the 
points of the funnels extending deep into the old bee 
burrows, and got a good living from the small fry that 
became entangled in the webs, such as visiting snout- 
beetles, ants, chalcids, flies, ete. I was surprised to find 
this spider actually feeding upon the bug, Reduvius per- 
sonatus Linn. [W. L. McAtee]. Occasionally, however, 
the spiders themselves fell prey to some predatory 
wasp. 
Spider, Steatoda borealis {[J. H. Emerton]. 
Among the most important renters of the old burrows 
in the bank were the spiders, Steatoda borealis. They 
made light, irregular snares about the bank, more often 
about the old burrows, where many of the smaller in- 
sects became their prey. I have often seen Chalcid para- 
sites and ants, Crematogaster lineolata, entrapped in 
their snares. The species may rightly be regarded as 
an inhabitant of the bank, either a renter or a pioneer. 
They were very numerous in 1917, and only moder- 
ately so in the following years. They were as abun- 
dant as ever even so late as October 3, when one spider 
was making several brave attempts to subdue a large lo- 
cust, Tettigidae lateralis var. polymorpha Burm. (A. 
N. Caudell), which was entrapped in its web. Two un- 
identified beetles were also their victims that day. 
Résumé of Renters. 
The following table summarizes the renters in this 
social group. They number eleven species, of which 
seven are wasps, two are bees, and two are spiders. All
