Key words: Europe B Proctotrupidae B Diapriidae BScelionidae B new species. Buhl, P. N.; Parmagade 36, st tv, DK-2300CopenhagenS, Denmark. Four of eleven new species described below were collected in connection with a fragmentation experiment in boreal spruce forest, carried out by the Norwegian Institute for Nature Research (NINA - cf. TpmmerSs & Breistein 1995). Six of the remaining species were sent to me by Mr. Lars Ove Hansen (Zoological Museum, University of Oslo), five of them in connection with a survey of the Norwegian proctotrupoid fauna to be published soon. The last remaining species I have collected in Denmark. The type material is deposited in the Zoological Museum, University of Copenhagen (ZMUC) and in the Zoological Museum, University ofOslo (ZMUO).

Runs to P. leviventris (Kieffer, 1907) in Nixon's (1957) key and generally similar to this species, but gravlundi has radial cell sharply closed and T2 without distinct punctures. Whereas petiole of leviventris has longitudinal carinae uneven and interrupted by transverse carinae, gravlundi has the two dorsal longitudinal keels even, uninterrupted on a smooth background. The punctation of sternite 2 is much finer in gravlundi than in leviventris. P. gravlundi has marginalis hardly halfas long as its distance from basalis and three-quarters as long as stigmalis which is 0.3 as long as the radial cell.

Propentacantha") autumnalis (Thomson, 1859) in Kieffer's (1926) key, but this species has T1 striated, only slightly humped anteriorly, and A2-A4 each not longer than wide. In shape of metanotal spine and T1 cornutus sp. n. seems to be similar to T. nigrinotum (Dodd, 1914) from Australia, but this species has frons entirely striated, T3 smooth, thorax and T1 reddish, and legs golden-yellow (cf. Dodd 1930). Trimorus microspinus sp. n. Holotype ?, Norway (EIS 35), BV, Rollag, Varviken, VI11.1995, Malaise trap, leg. L. O. Hansen & B. A. Sagvolden (ZMUO). Female. Body length 1.1 mm.

T3 distinctly reticulate, rather shiny, almost 1.2 times wider than long. T4 with finer reticulation, T5-T7 with microsculpture and some punctures. Male. Unknown. Runs to T. autumnalis (Thomson, 1859) in Hellen's (1971) key, but this species has no longitudinal line on frons and almost circular metasoma.

T1 smooth except for a few striae laterally; T2 one and two-thirds times longer than wide, striated to one-third of length, rest of tergite with uneven surface to three-fourths oflength; T3 almost smooth; apical tergites forming a long, upturned tail. Male. Unknown. Rather similar to T. promachivorus (Gahan, 1924) and T. benefactor (Crawford, 1911), but these two species have more transverse head and less slender antennae than ilione sp. n. (cf Crawford 1911 and Kozlov & Kononova 1983). T. benefactor and another similar species, T. lopicida Silvestri, 1932, also differ from ilione sp. n. in having a hump on T1 (cf. Masner 1976 and Kozlov & Kononova 1983). Acknowledgements 1 wish to thank June Breistein from NINA, Trondheim, and Lars Ove Hansen, Zoological Museum, University ofOslo, for sending me the material.
