b) Berlese selector. When the sifting of the material must be avoided for the sake of soft-bodied insects, a Berlese selector is to be used. Small probes of any decaying material, humus or soil samples are placed on a sufficiently tight mesh and kept there till dry. The jar or tube beneath the plastic funnel contains ethanol for the instant preservation of the small insects. The type of Berlese selector used has been described in a publication by J. BALOGH Sc S. MAHUNKA. Water collections According the nature of the waters and the expected material, three different methods have been applied: a) With drawing net in stagnant waters. b) By a filtering method. A plancton or water net is kept or fixed downstream, and the stones, sand, gravel or mud of the stream bed are scratched over the net. The floating insects, together with some litter, are filtered by the net. c) Singled collection from under stones in water. In cases where method b cannot be applied,the insects have been collected with Leonhard forceps from the bottom of quickly-lifted stones. In the first two methods, if much litter lias been filtered together with the insects, the material is placed on the horizontal wire mesh of a Moczarsky-Winkler selector on the spot for dropping and preliminary selection. Shore washing This new method of floating of the shore insects is designed to replace the difficult method of damming, described by earlier authors. The advantage of shore washing compared with damming is that it can be used equally well with stagnant waters and streams without the tedious process of dam building. Eight to ten bucketfuls of water are splashed over the same
