THE GRASSHOPPER'S COUSINS
says the notes "are sharp, snapping crepitations and sound like the slow snapping of the teeth of a stiff comb as some object is slowly drawn across it." He represents them thus: tek-ek-ek-ek-ek-ek-ek-ek-ek-ek-ek-tzip. But, however the song of Microcentrum is to be translated into English, it contains no suggestion of the notes of his famous cousin, the true katydid. Yet most people confuse the two species, or rather, hearing the one and seeing the other, they draw the obvious but erroneous conclusion that the one seen makes the sounds that are heard.

We now come to that artist who bears by right the name of "katydid," the insect (Fig. 24) known to science as Pterophylla camelli?folia and to the American public as the greatest of insect singers. Whether the katydid is really a musician or not, of course, depends upon the critic, but of his fame there can be no question, for his name is a household term as familiar as that of any of out own great artists, notwithstanding that there is no phonographic record of his music. To be sure, the cicada has more of a world-wide reputation than the katydid, for he has representatives in many lands, but he has not put his song into
