The same vein on the right wing (B) is much smaller and has no file, but the inner basal angle ot the tympanum is produced into a large lobe bear- ing a strong scraper (s) on its margin. The quality of the katy- did's song seems to differ somewhat in different parts of the country. In the vicin- ity of Washington, the in- sects certainly say ka-ty-did as plainly as any insect could. Of course, the sound is more literally to be represented as ka ki-kak', accented on the last syllable. When only two syllables are pronounced they are always the first two. Sometimes an individual in a band utters four syllables, "katy-she-did" or ka ki-ka- kak\ and again a whole band Fig. 26.

In New England, the katydids heard by the writer in Connecticut and in the western part of Massachusetts uttered only two syllables much [48].
