160 ORDER IV. Phryganea. 



Schasffer has divided this Genus into the Per- 

 la and Phryganea, with the fame diftincT: charac- 

 ters as GeofFroy 5 thefe two authors, I appre- 

 hend, were chiefly induced to purfue that me* 

 thod, becaufe the number of joints, of which 

 the Tarfi are compofed, obliged them to ar- 

 range the different kinds of Phryganeae under 

 different orders. 



The Antennas of the Linnaean Phry- 

 ganeae, are filiform, and they have three (lem- 

 mata. 



The leffer Phryganese refemble the Tineas fa 

 much, asnot to be diftinguifned from them without 

 difficulty -, but, upon clofe examination, efpecially 

 if the eye is aided by the microfcope, the 

 wings of the firft are found to be almoft co- 

 vered with fhort hairs inftead of the fcales 

 which adorn the wings of the Tineas. The 

 mouth of the Phryganea is like wife furnifhed 

 with palpi, which are wanting in the Tineas. 



The larvas belonging to this Genus, live in 

 the water in tubes of filk 5 covered on the out- 

 fide with fmall pieces of wood, fand, gravel, 

 leaves of plants, &c. Nay, fometimes the larva 

 attaches to its tube the fmaller teftaceous ani- 

 mals.
