that which is caufed by the hands in endeavouring to take it; fince it inftantly takes to flighty 
and difappears ^ hence it happened that I was fome confiderable time before I could colledt 
fufficient fpecimens. The female colleds her eggs into a thick round bag, of a greyidi 
colour, the fize of which is reprefented by the ring, at fig. i . This bag is not faftened 
to the fexual organ, as in other females of this divifion, but is entirely feparate, and kept 
clofe to the thorax, by means of the arms. It is however no hinderance in running, the 
length of her legs preventing it from ftriking againfi: any obftacles in her way. The follicle, 
or egg-bag, is preferved with as much care as her life : I never faw her hunting after food 
while fire carries it: it contains about 150 eggs. The young come out at the end of July; 
they have dark thoraxes, with a lucid longitudinal line; and their abdomens are dark, with 
three fmall lucid rays towards the thorax : their legs are whitifir, with confpicuous prickles 
on them. The young run about in the nefts, and do not adhere to the back of the mother, 
as mofi; others of this divifion do. 
Having often feen thefe Spiders catch flies upon the wing with great fwiftnefs, I doubted 
whether they made any webs ; but having kept a male feveral days without food, I found 
him weaving a web of a particular form. He faftened a little net to the fide of the place 
where he was confined, in form of a bag, whereof the circumference of the aperture exceeded 
the height about ten times : acrofs the aperture ran in a confufed manner fome thick threads : 
the bag was placed in a plane nearly oppofite to the air, was narrower towards the bottom, 
and ended in flue. The Spider did not live in this web, but walked at large about the fides 
of the place where he was, feizing on the flies, both on the wing, and entangled in the 
web.
