These fringes characterise the order, which in other re- spects is closely allied to the Orthoptera, and they give the name to it. The Thysmioptera (Ovo-avoL, fringes; iiTepov, a wing) have filiform antennae and very large eyes, and the different species of the genus Thrips have a great diversity of wing fringing. The structure of the wings is somewhat analogous to that observed in the Lepidopteraj in the Pterophorina, and the Alucitina. The metamorphoses of the Thysanoptera have not received ^ much attention, but they are known to be of the incomplete kind. The quiet chrysalis condition is not observed, and the larvae are born from the o^gg^ greatly resembling the adults. The absence of wings is the great distinction between the larval and the imago state, as it is in the closely-allied order of the OrtJwptera. The larva moults several times, and the wings are gradually added, the colour of the insect altering 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 Duncan, P.
