In order to give the journal a more The Editor international appearance, the name was changed to Norwegian Journal of Entomology with Volume 22 in 1975. In 1979, support to the journal from The Norwe gian Research Council was discontinued. The council expected taxonomic and ecological papers to be published in international Nordic journals, like Oikos, Holarctic Ecology and Entomologica Scandinavica, which they supported. One problem remained. There was no journal for publishing local, faunistic papers. The situation changed later in the same year, when The Norwegian Research Council decided to sup port a series offaunistic journals. Our journal was continued as Fauna Norvegica Series B, with subtitle Norwegian Journal of Entomology. Up to 1993, Series B was published by Norsk zoolo gisk tidsskriftsentral at The Zoological Museum in Oslo, but from 1994 publication was taken over by Norsk institutt for naturforskning (NINA) in Trondheim. Due to financial problems, however, NINA deci ded to discontinue publication of the journal from 1998. For this reason, since 1999 the journal has again been published by The Norwegian Ento mological Society. The name was changed back to Norwegian Journal of Entomology, and the journal receives support from The Norwegian Ministry of Environment. «Catalogus Lepidopterorum Norvegiae» Dette er titteIen pa den trykte kataIogen over Norges somrnerfugIer.
