TRICHOPTERA (Caddis-flies). Four membranous wings ; the 

 anterior generally hairy, the posterior folded when at rest. 

 Mandibles rudimentary. 



The antennas are many-jointed, setaceous. The maxillary 

 palpi vary considerably in structure. The wings have longi- 

 tudinal nervures and few transverse ones ; and in repose they 

 are closed up and deflexed in an almost vertical manner. The 

 hairs covering them are mostly simple, but occasionally inflated 

 and scale-like. The abdomen has nine segments, the last bearing 

 appendages of very varied kinds. The tibiae are furnished with 

 fine spines and also with movable spurs ; the tarsi have a pair of 

 simple claws, between which is a short cushion [plantula] and 

 two membranous "arolia." 



The larvae are six-footed and aquatic, and construct cases of 

 bits of leaves, twigs, straw, sand, or shells ; in these cases the pupa 

 stage is assumed. 



M'Lachlan gives eight families for the European fauna. These 

 families include all the species known at present.
