Julus

legs and body

JULUS, in natural history, a genus of insects of the order Aptera. Lip cre nate, marginate; antenna: moniliform ; two feelers, filiform ; body long, semi cylindrical, consisting of numerous trans verse segments ; legs numerous, twice as many on each side as there are segments of the body. There are fourteen species, of which we shall notice the J. Indus, or great Indian julus, which is six or seven inches long ; found in the warmer parts of Asia and America, inhabiting woods and other retired places. It has 115 legs on each side ; the body is ferruginous ; legs yellow ; the last segment of the body is pointed. The most common species is the J. sabulosus, about an inch and a quarter long; the colour brownish black, except the legs, which are pale or whit ish; it is an oviparous animal ; and the young when first hatched are small and white, and furnished with only three pair of legs, situated near the head ; the re maining pairs, in all 120, do not make their appearance till some time after.

This species inhabits Europe, and is found in damp places and in nuts. The juli tribe are nearly allied to the scolo pendrm, or centipedes, but their body, instead of being flattened, as in those in sects, is nearly cylindrical, and every joint or segment is furnished with two pair of feet, the number on each side doubling that of the segments, but in the scolopendrz the number of joints and of feet is equal on each side. The eyes of the juli are composed of hexagonal con vexities, as in most of the insect tribe, and the mouth is furnished with a pair of denticulated jaws. When disturbed, the job' roll themselves up into a flat spiral: their general motion is rather slow and undulatory.
