A very curious description, sometimes found in this country, but more generally in Italy, is the hunting-spider, so called because, instead of spinning webs to entrap their prey, they pounce on them, and devour them. This spider is small and brown, but beautifully spotted, with its hinder-legs longer than the rest. When one of these spiders sees a fly three or four yards off, it does not attack it without some deliberation as to the best means of doing so. Generally speaking, it creeps under it, and then, stealing softly up, it seldom misses its prey. If, however, on a nearer approach, it finds that it is not in a direct line, it will immediately slide down again, and the next time, making its observations more correctly, it pounces on the unsuspecting fly's back. Meantime, if the fly moves, the hunter follows its example, always taking care to face its prey. Should the fly, however, take wing, its enemy will follow it, swift as the lightning's flash, and then, moving almost imperceptibly along, she catches it by the poll, and, after quietly satisfying the pangs of hunger, carries the remainder home, to keep for a future day. The nest of these spiders is very curious: it is about two inches high, and is composed of a close and soft satin-like texture. In this are two chambers, placed perpendicularly, in which the spider reposes during the day, generally going out to _hunt_ after nightfall. The parent hunter regularly instructs her young ones how to pursue their future avocation, and when, in teaching them, they themselves happen to miss a jump, they always run away, as if quite ashamed of themselves! One of the largest kinds of nests to be met with in this country is that of the labyrinthic-spider, whose web most of our readers must surely have seen spread out like a broad sheet in hedges, generally in the furze, or other low bushes. The middle of this net, which is of a very close texture, is suspended like a sailor's hammock, by fine silken threads fastened to higher branches. The whole curves upward, sloping down to a long funnel-shaped gallery, nearly horizontal at the entrance, but winding obliquely until it becomes almost perpendicular. This gallery is about a quarter of an inch, is much more closely woven than the sheet part of the web, and generally descends into a hole in the ground, or else into a soft tuft of grass. Here is the spider's dwelling-place, where she may often be found resting with her legs extended, ready to catch the hapless insects which get entangled in her sheet net.
