ISTANCE, however, lends enchantment to the song of the katydid, for it grates on our nerves as well as on our ears, when at close quarters. The katydid makes his music in a manner similar to that of the cricket but is not, however, so well equipped since he has only one file and only one scraper for playing. As with the meadow grasshoppers and crickets, only the males make the music, the wings of the females being delicate and normally veined at the base. The ears, too, are in the same position as those of the cricket, and may be seen as a black spot in the front elbow. The song is persistent and may last the night long: "Katy did, she didn't she ; James Whitcomb Riley says, "The katydid is rasping at the silence," and the word rasping well describes the note. The katydids are beautiful insects, with green, finely veined, leaf-like wing-covers under which is a pair of well developed wings, folded like fans; they resemble in form the long-horned grasshoppers.

Sometimes this region is pale brown and sometimes green, and with the unaided eye we can plainly see the strong cross-vein, bearing the file.
