fajjal tévesztették össze. Feltehetően tápnövényével, a szintén közép-ázsiai eredetű Eleagnus angustifolia-val hurcolták szét Európában a Macropsis eleagni Emeljanov kabócafajjal együtt . Eddig a Szovjetunió területéről Moldáviából, Ukrajnából, a Krímből, Oroszország középső és déli részéről, Grúziából, Örményországból és Azerbajdzsánból, azonkívül Romániából, Iránból és Anatóliából mutatták ki. A fajt az utóbbi években további országokban sikerült megfognunk, itt most részletesebben csak a magyarországi és bulgáriai adatokat közöljük. A faj feltehetően minden olyan európai országban megtelepedett, ahol tápnövénye és a klimatikus viszonyok lehetővé teszik egy második nemzedék kifejlődését is. Csehszlovákiában októberben, nem sokkal lombhullás előtt még sok lárvát, köztük fiatalokat is sikerült fogni,és feltehető, hogy azok elpusztulnak, mert csak a kifejlett egyedek telelnek át. A magyarországi példányok adatai: Siófok, 1979. X. 11., 16 hím, 22 nőstény; Bugac, árok mentén a Múzeum közelében, 160 m, 1987. VII. 13., 6 hím, 9 nőstény. A bulgáriai példányok adatai: Antonovo és Kesarevo között, Targoviste közelében, útszélen, 450 m, 1987. VII.24., 2 nőstény. Trioza neglecta Loginova, 1978 is a species of central Asian origin, the same as its host plant, Elaeagnus angustifolia

. The species has been described only recently; previously it was mistaken for Trioza elaeagni Scott (Dobreanu et Manolache, 1962) or Trioza magnisetosa Loginova (Loginova, 1978) . The two latter species have much narrower ranges and lack a wider ecological potency that would enable them to immigrate other climates and artificial caenoses in towns, etc. With the introduction of various cultivars of Elaeagnus angustifolia, a decorative shrub, T

. neglecta was introduced, together with the leafhopper Macropsis elaeagni Emeljanov [Tauterer, 1984), into all sorts of places in Europe. So far, T. neglecta has been reported from the territory of the USSR from Moldavia, the Ukraine, the Crimea, the central and southern part of the Russian Federation, Georgia, Armenia and Azerbaijan, furthermore from Rumania, Iran and Anatolia. It is new for the territory of Hungary and Bulgaria; the authors' further findings will be published elsewhere. The authors found the species also in Czechoslovakia in Moravia and Slovakia , Rumania and Yugoslavia, and received material for determination from Turkey from the close environs of Adana where specimens were found on apple trees (25.IX.

1978, lo ;, and 1979, Id*, 1 o., all leg. Y. Ylgit ). Beyond doubt, the species has been introduced to other European countries as well, where the authors were unable to collect, and its distribution in Europe is apparently limited only by climatic conditions which would permit complete development of a second generation. The authors have found no difference in the infestation of various cultivars of the host plant. The species is bivoltine throughout its range. In central Europe, adults of the first generation emerge in mid-June to late June and July; those of the second generation emerge rather late, from early September to early November when the host plants shed their leaves. In Czechoslovakia, large numbers of larvae of this species, even younger instars, can be found on the lower surface of lea\res of the host plants still at the end of October, shortly before leaf fall. This means that a considerable part of the second generation will die and that central Europe is probably passed by the limit of the possible distribution of the species in the case of incidental introduction. The species apparently hibernates in the adult stage; the authors have not yet succeeded to find overwintered adults in spring. The larvae on their dorsal side have dense, long and fine hair-like spines. The morphology of larvae and adults or" this species and its allies is slightly different from the current type in the genus Trioza

, and it is probable that they form a group of higher taxonomical value within this heterogeneous genus. Localities in Hungary: Hungária occ
