MIMICRY IX SPIDERS. 369 It would be strange if all these were one species, differently colored accord-ing to the place they dwell in, and having power to change from purpleor white to yellow at will; yet tliis seemed probable to us. Or was itthat a species had developed these different varieties, each adapted to liveon a certain plant? However this may be, the arrangement evidentlyresulted in a twofold advantage, in that it enabled the spiders to escapethe peering eyes of birds, and at the same time to lie in wait unperceivedfor the insects of various sorts that frequent such flowers in great num-bers. In no case, it may be added, did we see a purple spider on a yellowflower, or vice versa. Mr. Cambridge has observed and recorded like facts of Misumena vatiain England. 1
