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.
