the holes and crevices of wooden partitions, abandoned by

it has found a convenient cavity for the purpose, seizes on a 
spider, which it kills, and deposits it at the bottom ; then 
laying her egg in it, she closes up the orifice of the cavity 
with clay; the larva, which resembles the maggot of a bee, 
having devoured the spider, spins itself up a dusky silken 
web, and changes into a chrysalis, out of which, within a 
certain number of days, proceeds a comple insect, which is 
black, with a slightly foot-stalked abdomen, the edges of 
the several segments being of a brighter appearance than

about two days.
