Like its cousin the lobster, the insect, in its imago or perfect state has a body, the latter part of which is composed of rings. There are ten or eleven of these rings, the ones toward the head being very like each other, but toward the tail end there is a marked alteration in 'size and form. The last three or four segments or rings are usually very much reduced in size, particularly on the under side, thus causing the end of the body to curve in. The

The last three or four segments or rings are usually very much reduced in size, particularly on the under side, thus causing the end of the body to curve in. These smaller segments give rise to certain long, slender growths on the under side, ultimately form- ing tubes, capable in some cases of being with- drawn into the body. These terminal organs, in some species, are very complicated. As in other creatures, the ovaries of the insect lie one on each side of the inner cavity of the body, egg-tubes or oviducts leading from them to the outer world. In the male, sperm-sacs and sperm- ducts take the place of ovaries and oviducts. The oviducts and sperm-ducts communicate at their outer opening with the elongated terminal organs, which, in fact, form tunnels through which the eggs and sperm-cells may be safely conducted to any given 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 Morley, Margaret Warner, 1858-1923.
