needed type material. From the 1950s on, he began to be very active in the following main lines of research: To survey the fauna of Hungary and that of the Carpathian Basin. From 1957 till 1980 he wrote numerous summarizing articles in which the latest faunistical results were published, mostly on the large groups of Lamellicornia and Rhynchophora, with special regard to the Börzsöny Mountains. In the series of the Fauna of Hungary (Fauna Hungáriáé), launched by the Hungarian Academy of Sciences, he wrote the respective parts of Lamellicornia and Rhynchophora (excepting the family Apionidae). In our home literature these volumes were the first to treat in detail these two superfamilies, which for some time to come set the line of investigations not only for Hungary but, in spite of its Hungarian language, for the research of Central Europe, too. Since the appearance of the volumes a clearly noticeable upswing could be observed in the study of these beetles. As the result of his faunistical researches today an exactly identified large material of the Carpathian Basin is housed in the Zoological Department of the Hungarian Natural History Museum, which is important even when measured with international standard. The study of Lamellicornia on world material. His first contribution on this line appeared in 1938: the revision of Oryctes

. In 1941 he published the revision of the genus Megasoma, in 1947 the genus Dynastes

, in 1951 the genus Goliathus, in 1952 the genus Anthypna

, then from 1955 on, he began to work on the African groups of Aphodiinae: in 1955 those from Ruanda-Urundi, in 1960 East Africa, in 1964 Belgian Congo, in 1981 South Africa. Besides these large contributions, of course, he published many smaller articles bringing out many scientific novelties. In the 1960s he resumed to his old plans and began to make revisions and monographic elaborations of the rhinoceros beetles on world level. Between 1966 and 1977 he published the results of his studies in 20 parts of some 1600 pages, both in Hungarian and foreign scientific journals. This series brought him international recognition and later instigated him that these 20 parts published in 8 different journals be compiled into one integrated whole. Thus, in 1977 he began to Concentrate all his energies on the writing up of this work. The Hungarian Academy of Sciences provided him the opportunity to publish this rather voluminous work in one volume, which came out as a joint edition with the Dr.W. JUNK by Publishers in early 1985, running up to some 800 pages. He wrote over 200 scientific papers. His works appeared in 22 countries, in the beginning mostly in German, later in English. Of course, his faunistic investigations concerning the Carpathian Basin were published in Hungarian. He spent some 20 years in the Zoological Department of the Hungarian Natural History Museum, during which time, he built out an extensive correspondence with people all over the world. He was always ready to help in any question in which he felt himself competent. In recognition of his scientific achievements in 1957 he received the academic degree of "candidate of science" in biology. He was member of the organizing committee of the Central European International Entomofaunistic Symposium (SIEEC). At the VHIth Symposium he was awarded the medal " I|n entomofaunistica excellenti" which was held at Hradec Kralove (CSSR). He was active member of the Hungarian Entomological Society for the last 50 years. He was honourable member of the Yugoslavian Entomological Society, and member of the Austrian and Bavarian Entomological Societies. His large special collections, like those of the Scarabaeidae and Melolonthldae, as well as the materials of Passalidae and Lucanidae were purchased by the Hungarian Natural History Museum. The Coleoptera material of the Börzsöny Mountains remained in his family's possession.He himself collected all over Hungary and in various parts of the Carpathian Basin. He visited Ghana and South Africa several times, helped mostly by his son, Dr. Sebastian ENDRŐ DY-YOUNGA, where he made extensive collectings for the Hungarian Natural History Museum, Budapest. His memory will stay with us for a long time to come, as his lasting works will retain his name in the international scientific literature. Dr. Zoltán KASZAB
