The captures of Sarracenia, especially those of the larger southern species, offer many surprises: as we pass from one tall "pitcher" to another, lifting their lids and peering down the narrowing tubes, we find recent captures, moths, beetles, flies, wasps, grasshoppers, representatives of most of the prin-cipal orders of insects, attempting to scale the vertical walls which have already proved fatal to the earlier victims whose remains fill the lower tubes; we recognize the usual guest in-sects, Exyra, Sarcophaga, Isodoiitni, or the indications of their presence; and if the se.oon and locality be l.ixoruble, we may soon find a "pitcher" whose tube-, some inches belou the top, is closed by a mass of whitish froth-like filaments 91
