Eightyeight psyllid species are recorded in the area under examination. All of them are reported in a list, which is ordered by families and made up on the basis of bibliographical information, direct collec- tions on their host plants and captures by trays. Moreover, a few taxonomic notes are given on some species of little clear systematic interpretation. Zoogeographical information is also given on the species under discussion, determining that the groups of the widely diffused in the Palaearctic and of the European species are the most represented in the psyllid fauna of the examined area. ' In the end, a few faunistic notes are reported on the psyllid of the Italian administrative region Friuli-Venezia Giulia. The knowledge on the jumping plant lice (Psylloidea) of the South-Ea- stern Alps is rather fragmentary and dispersed in numerous pubblications, which concern different subjects. The present note wishes to gather all the available information on the topic, being it based not only on data from the literature but on both the direct field collections and captures by yellow water trays. Most of the for- mers have been carried out by one of us (C.R.); other samples come from Prof. L. Masutti (Istituto di Entomologia agraria, Universita di Padova) and Mr L. Tamanini (Museo civico di Rovereto, TN). The captures by trays have been realized near Gorizia and Udine, during 1984 and 1985, and the speci- mens have been sent to us by Mr P.G. Coceano (Centro Regionale per la Sperimentazione Agraria, Pozzuolo del Friuli, UD). We acknowledge with many thanks the kind help of the mentioned Authors. DEFINITION OF THE INVESTIGATED AREA In the present study, the Adriatic side of South—Eastern Alps and Pre- Alps has been investigated, including the Italian slopes of Carnic Alps and (*5) Research work supported by CNR, Italy.
