Zorotypus, winged form (Caudell) Zorotypidae. no wider than the head; prothorax free, not concealing the head nor expanded laterally; meso- and metathorax distinctly separated. Abdomen elongate-oval, never much longer than the thorax, with ten strongly transverse segments; cerci short, oval, one-jointed, with a bristle-like appendage at tip. Legs similar, formed for running; hind femora stout, sometimes armed beneath with spiny bristles; tarsi two-jointed, the first joint short, the second with two claws at tip. Metamorphosis gradual, the nymph similar to the adult, especially to the wingless form. Winged form with narrow, membranous wings, the fore pair larger; venation greatly reduced; wings commonly falling off after maturity, leaving a stub attached to the body, but not separating at a preformed suture; body of winged form more heavily chitinized than in the wingless 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 Harvard University.
