In connection with studies of the use of fluorescent lamps for May-beetle control, which have been made during the past two years at Sanmyoji nursery, a number of experiment have been made with the release and recovery of marked beetles. A part of these studies reported herein, and the results summarised as follows : (1) "Himekogane" (Anomala rufocuprea Motschulsky) exhibited the highest recoveries among many species of May-beetle.(2) Of the beetles released at places 160 m or more away from the light sources or places from where the lamps were visible poorly owing to the state of topography, very few were recaptured.(3) The percentage recovery of the beetles liberated in windbreakwoods was also very low, and outside of them lower.(4) Meteorogical conditions (especialy, temperature, humidity, quantity of cloud, phase of the moon, force of wind) always influenced flying activity of the beetles.(5) As the distance from the liberated point to a lamp increased, the percentage recovery diminished successively, showing the curve hyperbola.(6) The majority of the beetles responded to the light were attracted within 30 minutes.
