Length .80 of an inch. Head oblique, narrow, slightly bilobed, about one-fourth of the head above the height of joint 2; body nearly cylindrical; on joint 5 a nearly conical projection about two-thirds as high as the depth of the body, bifid at the top, each part tipped with a hair; on joint 9 is a slight elevation, and a more prominent one on joint 12. When at rest the posterior part of the body is raised, making these elevations appear more prominent. In color, the head, joint 2, and the dorsum of joints 3 and 4 to the top of the tubercle on joint 5, is dark brownish purple mottled with gray, the sides being lighter than the front of the head and the dorsum, the latter narrow posteriorly; the sides of joints 3 and 4 are bright green with a few fine purple dots and a pale dorsal edging; the sides of the body back of joint 4 are a series of fine, close, crenate purplish red lines or mottlings on a grayish yellow ground color, more yellow above, giving the sides something of an orange appearance; the dorsum of joints 5 to 8 is more of a grayish color from the ground color being paler and the mottlings finer and more of a purple shade; a darker patch on the dorsum of joint 8, this color extending back obliquely on joints 9 and 10, making a dark purple lateral line; the pale part of the dorsum is wider on the posterior than on the anterior of each joint, the space being boldered by an oblique purpte line that fades out before quite reaching the lateral line; the rest of the dorsum is like the sides, except a little darker I between the two posterior tubercles or elevations is a clear white V, the point beginning on the anterior part of joint 10 and extending back to the posterior part of joint 11 on the sides.
