NEOTROPICAL CADDIS FLIES I — FLINT 



459 



The structure of the mouth parts, legs, and other sclerotized areas 

 of the body seem to be geuericaliy constant, at least in the other 

 larvae of this genus known to me. Inasmuch as the larva of only one 

 other Neotropical hydrobiosine genus (described on p. 462) is known, 

 it is impossible to prepare generic keys to the larvae.
