47^ fHRYGANEA* 



Genus III Phryganea. 



T HJESE infers, as well as the lad, are of a fmall fize, 

 and are at fuft iight eafilj diftinguifhed by tlie antennaep 

 •which are longer than the thorax, or even the whole 

 body. The mouth is without teeth, but furnillied with 

 four palpi ; the four wings are incumbent ; the under 

 ones, when unfolded, are very broad in proportion to the 

 lizc of the animal tiiat wears them *. 



There are twenty- fur fpccies ranged under this tribe, 

 which Linnceus has divided into two families j the firft 

 char .£leriied by having the fetae which fpring from the 

 extiemity of the abdomen truncated like the beards of an 

 ear of corn ; and the fecond, by having the abdomen 

 fi-rple, without appendices. 



The phryganeae, before they become inhabitants of the 

 air, h.ive, like the ephemercs, been aquatic animals ; their 

 apartments in the water are lingularly conftrufled \ their 

 form is that of a tube, the inward texture of which is 

 filk, while it is outwardly compofed of fand, ftraws, or 

 chips of wood. When the animal within finds its chry- 

 falid flate approach, it {lops up the ends of this tube 

 witli threads of a loofe texture, through which the water 

 may penetrate, while it prevents the approach of vora- 

 cious infc^ls.
