II.—"Shinné-shinné."
The shinné-shinné—also called yama-zémi, or "mountain-sémi"; kuma-zémi, or "bear-sémi"; and ō-sémi, or "great sémi"—begins to sing as early as May. It is a very large insect. The upper part of the body is almost black, and the belly a silvery-white; the head has curious red markings. The name shinné-shinné is derived from the note of the creature, which resembles a quick continual repetition of the syllables shinné. About Kyōto this sémi is common: it is rarely heard in Tōkyō.
[My first opportunity to examine an ō-sémi was in Shidzuoka. Its utterance is much more complex than the Japanese onomatope implies; I should liken it to the noise of a sewing-machine in full operation. There is a double sound: you hear not only the succession of sharp metallic clickings, but also, below these, a slower series of dull clanking tones. The stridulatory organs are light green, looking almost like a pair of tiny green leaves attached to the thorax.]

III.—Aburazémi.
The aburazémi, or "oil-sémi," makes its appearance early in the summer. I am told that it owes its name to the fact that its shrilling resembles the sound of oil or grease frying in a pan.
