( 71 ; VI. On the Lamellicorn Coleoptera of Japan. By Chas. O. Waterhouse. [Read March 15th, 1875.] The present paper is intended to give a complete account of the Lamellicorn Coleoptera, known at the present time to be inhabitants of Japan. A considerable collection was brought to this country by Mr. George Lewis, containing, as will be seen from the list, very numerous species new to science, all collected in South Japan. I have added to this list a few new species from the northern island, and such others as have already been noticed as inhabitants of Japan. SCAEAB^ID.E. Temnoplectron parvulum, C. "W.
