genus abound in tropical and subtropical regions their webs are composed of two kinds of silk one yellow exceedingly viscid and elastic the other white dry and somewhat brittle the latter is used for the framework of the web the guys aad d radii and the former for the concentric rings these snares are at varying heights sometimes within reach again 10 to 12 feet from the ground but always in a position exposed POs ed to the rays of the sun sum the diameter is also variable from three feet upward one seen by graffe in the fiji islands constructs a web 30 feet in diameter these snares are strong enough to entrap small birds in the authors opinion the web is not set for or such game and the spider does not feed on her ornithological victim in the cases where she has been observed with her fangs in the body bod of the ensnared bird it is probable that it Is for the purpose au of hastening the death of the bird in order to prevent its injuring the web in its ats sz struggles ruggles to escape spiders of the genus are easily tamed although exceedingly voracious they can exist tor for many days without food or water american naturalist tab alf factor of safety mechanical engineers
