met with in all winged insects ; and the pedal organs may occur in 
several parts of the legs {Coleoptera, Phryganeidce) ^ or may<be restricted to 
certain parts. They may be either femoral {Pediculidce), tibial (Ortho- 
ptera^ Pseudoneuroptera, Formicidce), or tarsal, {Coleoptera, &c.). The 
tympanal organs in the front legs of Locustidm and Gryllidm correspond 
to atympanal organs in the other legs. The occurrence of these differen- 
tiated and undifferentiated organs in these insects, as well as in the 
Blattidm, and especially in the A cridiidce^ which are also provided with 
abdominal tympanal organs, is highly interesting ; and the author can 
scarcely doubt that these peculiar structures are organs of hearing.
