These fringes characterise the order, which in other re-spects is closely allied to the Orthoptcra, and they give the nameto it. The TJiysanoptera (dvcravoL, fringes; irTepov, a wing) havefiliform antennse and very large eyes, and the different species ofthe genus Thrips have a great diversity of wing fringing. Thestructure of the wings is somewhat analogous to that observedin the Lcpidoptcra, in the PtcropJiorina, and the Alucitina. The metamorphoses of the TJiysanoptera have not receivedmuch attention, but they are known to be of the incomplete quiet chrysalis condition is not observed, and the larvae areborn from the q^^, greatly resembling the adults. The absenceof wings is the great distinction between the larval and the imagostate, as it is in the closely-allied order of the OrtJioptera. Thelarva moults several times, and the wings are gradually added,the colour of the insect altering CHAPTER X. THE N E U R O P T E R A. All the varieties of metamorphosis may be observed amongstthe Neuroptera. Some of these insects never have a period ofinactivity, and do not undergo greater transformations than theOrthoptcra. But others have to submit to two metamorphosesbefore they become perfect, and the transformations are assharply defined as they are in the Ltpidoptera. These last undergocomplete, and those just mentioned pass through incomplete,metamorphoses. Other Neuroptera remain in a condition of inaction for a veryshort time, and their nymphs lose their activity and undergo arapid metamorphosis, as it were, at the very moment when
