THE GRASSHOPPER'S COUSINS The song of ensiger sounds like the noise of a miniature sewing machine, consisting merely of a long series of one note, tick, tick, tick, tick, etc., repeated indefinitely. Scudder says ensiger begins with a note like brw, then pauses an instant and immediately emits a rapid succession of sounds like chwi at the rate of about five per second and continues them an unlimited time. McNeil repre- sents the notes as zip, zip, zip; Davis expresses them as ik, ik, ik; and Allard hears them as tsip, tsip, tsip. The song of

It consists of a long shrill whir which Rehn and Hebard describe as a continuous zeeeeeeeeee. The sound is not loud but is in a very high key and rises in pitch as the player gains speed in his wing movements, till to some human ears it becomes almost in- audible, though to others it is a plain and distinct screech. A large conehead and one with a much stronger instrument is the robust conehead, Neoconocephalus robustus (Fig. 28). He is one of the loudest singers of North American Orthoptera, his song being an intense, continuous buzz, somewhat resembling that of a Cicada. A Caged Specimen Singing fore wings separated and in a room makes a deafening noise. somewhat .elevated- the head o downward The principal buzzing sound is ac- companied by a lower, droning hum, the origin of which is nor clear, but which is probably some secondary vibra- tion of the wings. The player always sits head downward. Fig. 28. The robust cone- head, Neoconocephalus robus- tus, in position of singing, with ?1.
