Satô, M.: Some notes on dytiscoid-beetles from Vietnam (Coleoptera)

ANNALES HISTORICO-NATURALES MUSEI NATIONALIS HUNGARICI Tomus 64. 1972. Some Notes on Dytiscoid-Beetles from Vietnam (Coleoptera) By M. SATÔ, Nagoya, Japan Through the courtesy of Dr. Z. KASZAB, Director General of the Hungarian Natural History Museum, I have examined a large number of Dytiscoid beetles in the collection of the Museum. These specimens were captured in Vietnam by Dr. T. Pócs in 1963. According to the identification 29 species belonging to 14 genera of 2 families can be listed : 1 subgenus and 2 species are new to science and described herein. I received aquatic beetles for determination also from Mr. S. INOUÉ in Osaka. Ten Dytiscoid species in his collection can be added to the previous list. I am very grateful to Dr. Z. KASZAB for the opportunity to examine the interesting specimens and the publication of the paper. I wish to express my gratitude to Mr. S. INOUÉ for his kindness in making available several specimens, and to Dr. A. TAKAHASHI for his kind preparing of the manuscript. Family Noteridae 1.
