This sac represents the membranous laby- rinth, and is connected with the auditory nerve, which goes to the brain. This tympanal structure is to be found in the common black .cricket, fa- miliar katydid, and their allies, on the inside of the tibia of the front leg. The organs of hearing have different locations in dif- ferent insects. It has been demonstrated that the an- tenna1 of the male mosquito vibrate to the sound-wave of the tuning-fork. It is quite probable that a num- ber of other insects per- ceive sounds through nerves which terminate exteriorly in the antenna1.
