. The Cambridge natural history. Zoology. CHAPTER XXI NEUEOPTEEA GONTIXVEB TRICHOPTEEA, THE PHKYGANEIDAE OR CADDIS-PLIES Fam. XI. Phryganeidae—Caddis-flies. (TEICHOPTEEA of MANY AUTHOES) Wings more, or less clothed with hair, nervures dividing at very acute angles, very few transverse nervides; hind pair larger than the front, with an anal area lohich is fr^equently large and in repose iMcately folded. Antennae thread- like, porrect, of many indistinct joints. Mandibles ctbsent or obso- lete. Coxae elongate and free but contiguoiis. Metamorphosis great; larvae caterp)illar-like, usucdly in- habiting cases of their o%on con- struction. Pupa resembling the perfect Insect in general form, becoming active previous to the last ecdysis. Wingless forms of the imago excessively rare. The caddis-flies are Insects of moth-like appearance, found in tlie neighbourhood of water; their larvae live in this element, where they may sometimes be found in abundance. Phryganeidae are not very attractive Insects, and there are few of large size; Hence they have been much neglected by entomologists, and very little is known about the exotic forms of the family. The habitations constructed by the larvae are, many of them, of a. -Hahsus guttatipeiinis. (After M'Lachlan.).
