The ovipositor is made up of several parts—a membranous tube (//), a chitinous hollow sheath (S) and a stout chitinous rod (R). The mem- branous tube (H) bears several ridges on its inner surface, and enters. Fig. 20. Chitinous plate on uterus and the parts of the ovipositor (greatly magnified). Fig. 20 (1).

The anterior end of the membranous tube is supported by a shears-shaped structure (C). This structure is made up of two chitinous plates (the handles of the shears) separated by a thin strip of membrane (see Fig. 20, C), and two membranous parts (the blades of the shears) darker coloured at their points on which are situated a few Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Association of Applied Biologists; Association of Economic Biologists.
