ROVARTANI KÖZLEMÉNYEK FOLIA ENTOMOLOGICA HUNGARICA (SERIES NOVAI 1959. TOM. XII. Nr. 11. Contributions to the ecology of beetles living on the forest-floor. By I. Popp Bakonyi Museum, Veszprém. Project. - In the spring of 1955 /27 IT­18 VI/ I made surreys on the ecology of beetles living on the forest floor of the Hárebokor-Hllle neer Budapest. According to botanists the foreet is e typicel Potentillo-Querceturn. Zólyomi ana­lysed the foreet botanieally, end the Team of the Zoosyste­matical Institution investigated it from the point of view of zoocoenology and production-biology. To complete their researches I strove to receive an approximative picture with regard to the quantitative data of some beetle species of the floor level. The aim of my Investigation wee to secure data on the following question: what kinds of numerical laws can be drawn from the behavior of beetle semaphoronts /Sze­lónyi/ belonging one or two fenotyp and of relatively small specimen numbers during the spring on the floor level of a forest of a known phytocoenological composition. To solve the complex problem as easy as possible I differentiated it into three points: 1/ The abundancy of the beetles on a given area. 2/ When does abundancy attain a relatively constant value in the course of the spring? 3/ The mobility of the beetles.
