Through the kindness of Dr. H. Höne, Bonn, I have the privilege of examining a large number of Pyralidae collected by him in China and Japan during his many years' residence in those countries. The material studied consists of duplicates of the vast co11ections sent to Prince Aristide Caradja in Rumania, and reported on by him in an extended series of papers in the years 1925 to 1939. In spite of his excellent taxonomic eye, Caradja did not study genitalia and rarely illustrated his species or discussed their structural characters. As Höne's collections have been the only ones to emanate from many of the regions he visited, and as Caradja's own collection, always remote, has for many years been inaccessible, and is believed to have been partly destroyed in wartime or post-war disturbances, the importance of the present material in elucidating the Caradja species is very great, and I owe Dr. Höne my most sincere thanks for permitting me to study it and to retain for the Canadian National Collection a substantial number of duplicates.
