The antennas are at least as long as the body. The legs are long, their length increasing from before backwards. Facetted eyes instead of ocelli. With a small number of free terga. Scut ig era colevjitrata L., South Germany and Italy. Order 2.—CHILOGNATIIA. The shape of the body is cylindrical or. subcylindrical. There is a four-lobed plate behind the mandibles, and two pairs of legs on each segment (the anterior segments excepted). The genital openings are on the coxal joint of the second pair of legs. The body of the Chilognatha is, as a rule, cylindrical or sub- cylindrical. The segments have the form of complete rings, or are prodded with special dorsal plates. In many cases (Julidce) the body is much elongated; in others (Glomeris] it is short, like that of a wood-louse (fig. 427). The antennae are short, and consist only of seven joints, b _<^i. of which the last may abort. The mandibles are provided with broad masticating FlG. 427.—a, Glomerit marginata (after C. L. Koch). 4, Maxillae Surfaces, which (inferior buctal plate) of Julus terrestria. serve to crush the vegetable matters on which the animals feed, and with an upper movably articulated pointed tooth. The maxillae are united so as to form an inferior buccal plate, the sides of which bear two rudimentary hook-shaped blades (fig. 427, b), while the middle portion appears to represent the underlip. The eyes, which as a rule consist of aggregated simple eyes, are situated above and external to the antennae. The anterior thoracic legs are as a rule directed forwards towards the mouth. The three thoracic segments, and sometimes the next two or three segments, bear a single pair of legs. All the others, except t
