were there it was just the opposite, out of the 11 days we spent in Da Lat on 9 days it was either drizzling with rain or heavy tropical showers came down at least once a day. For collecting adult Psocoptera, especially by beating the foliage and dry twigs the time proved to be a good one. The collected 150 specimens speak for themselves. Although our knowledge of the South-east Asian psocids is rapidly increasing lately, hardly anything has been known from Vietnam. Consequently, the number of specimens, though fair, is still significant. As far as the Neuroptera fauna of Vietnam is concerned, in recent years a few contributions have been published. It was a pleasant surprise of the second author that the majority of the about fifty Neuroptera specimens belong to the family of Coniopterygidae, which are rather difficult to collect. As far as we are aware no reference is known from Vietnam of this fragile, very interesting group. On the other hand, for successfully collecting the soil inhabiting fauna other factors have to be considered. In one particular locality a smaller amount of time is needed but different biotopes must be selected where samples are taken. As shown in the subsequent list we solved this question fairly well. A much greater problem is locally extracting the soil fauna (e. g. by using the Moczarszky-Winkler bags) since not much time is available in a foreign country and much depends on local temperature and air humidity. Consequently, we brought back various soil, moss, lichen, litter and other samples to Budapest, where they were warmed by electric light bulbs and the duration of extraction lasted for one month. The preliminary results already supersede all expectations. The several scores of samples endured the two weeks of polyethylene packing and transportation quite well. When we are referring to the Cam Ly area, which is not shown on any ordinary large maps, then we are talking about a private rain-forest occupying about 50 ha., some 10 km from Da Lat, owned by Mr. Tran Le, who actually finished his university studies in Szeged (Hungary) some years ago. This rain-forest lies in a valley directed NW-SE, occupying the best part of bottom and the NE side of the valley surrounded on the top and partly on the sides by much degraded area, utilized at best as grazing grounds, occasionally with newly planted young pine saplings. In the valley at places the granite boulders are cut by stone cutters. We should like to take the opportunity here to thank Mr. Le for his helping hand in providing us his jeep and his understanding in allowing us to visit his forest several times.
