landscape, but we exchanged extensive information on the systematics and ecology of the fauna and flora of these diverse landscapes. The recent paper in the Natural Areas Journal by Báldi (1999) outlined the great species richness of the country and shows how the work of many scientists, professional and non-professional alike, bring the true biological diversity to the attention of the scientific community - national and international. Our own work on the H. J. Andrews Experimental Forest, a Long-Term Ecological Research site in western Oregon, United States, has produced almost 4000 species of insects and other arthropods, but clearly, we have a long ways to go (Parsons et al. 1991). Several strokes kept me out of commission for a while, but I am back with the insects again, with a wonderful expanded vision, thanks to my Hungarian friends - köszönöm. My thanks to D. Tilles of the Valley Library, Oregon State University, for critical help in obtaining difficult literature, to B. Hall for her illustrations of the structures, and to L. Parks for manuscript preparation. REFERENCES Ashlock, P. D. and J. D.
