1. Sound guided through the tracheal tube to the internal tracheal spaces in the region of the cricket ear is capable of eliciting auditory neural responses in the prothoracic ganglion if the tympanal membrane is allowed to vibrate freely. If the tympanal membrane motion is prevented mechanically neural responses are abolished (Fig. 3) whereas the sound pressure in the tracheal air spaces behind the tympanum is increased.

2.\ If the motion of the tympanum, as measured with laser vibrometry, is prevented by adjusting the internal and external sound pressure, then neural responses cease simultaneously (Fig. 5).

3.\ These findings demonstrate that motion of the large tympanum is a necessary requisite in the sound transduction process of the cricket ear.

The copiphorine tettigoniid Mygalopsis marki uses two acoustic defensive displays which are quite distinct from the tegminal stridulatory mechanism. Both adults and nymphs utilise a stridulation produced within the head capsule. Observation and simple experiment reveal that this sound is produced in conjunction with the passage of air into the buccal cavity. There are large trachea beneath the frons which may be associated as amplifiers of these noises. The hind wings of the adults have small downward projecting spines set in open membranous areas of the wings. When the insect is excited, these spines engage a highly specialised area of the cuticle on the dorsal terga. The production of the noise requires only slight movement of the abdomen. Its role in defense is discussed.
