DISCUSSIONThe larvae of the Thaumaleidae inhabit thehygropetric zone of relatively cool springsand streams. Having amphipneustic respiratorysystem, with one pair of spiracles on thedorsal part of prothorax and one spiracle dorsallybetween the procerci (Saunders, 1923)they live partly submerged in the thin film ofwater flowing over rocks. The fauna of suchhabitats have not been examined in any extentin Norway. Although no immatures werefound at the site where T. verralli was captured,there is reason to believe that the localitysupports a population of thaumaleids. Accordingto Vaillant (1978) the imagines arerelatively sedentary and usually do not leavethe surroundings of the larval habitat.In contrast to the majority of Thaumaleidaespecies, T. verralli is widely distributedin Europe (Vaillant, 1969, 1978). The specieshas even been recorded from Iceland (Tjeder,1949b, Nielsen & al., 1954) and the Faroes(Pedersen, 1971). Vaillant (1978) listed T.verralli in «Limnofauna Europaea» as probablyoccurring in region 17, which includesDenmark and S. Sweden. The finding of thisspecies in region 20 adds weight to Vaillant'sexpectation and probably reflects that no intensivesearch for thaumaleids has been carriedout in Scandinavia to date. WesternNorway is relatively rich in hygropetric habitatsand although Vaillant (1978) pointed outthat there seem to be no exclusively borealspecies of thaumaleids in Europe, there isreason to expect that the number ofspecies inScandinavia may be higher than shown asyet.ACKNOWLEDGEMENTI thank Dr. F.

B 34, 31-34.A total of 316 specimens ofB. nigriventris Haliday, 1833, based on old revised and newcollections, have been recorded from around 70 localities. The distribution of B.nigriventris in Norway is given. B. nigriventris is common in the lowland north toTroms province, and is probably one of the most common species of Bibionidae inNorway. The species has been collected up to 900 m a.s.l. which belong to the subalpinezone, but it seems to be rare here. Most records are from mixed coniferous anddeciduous forests.The flight period is late May to July in the lowlands, except in the two northernmostprovinces where the flight period is June to early August. The few records from thesubalpine zone dates to late June and July. The sex ratio in all the material is I : I, but inMalaise traps the sex ratio changes towards 2 males per I female.Uta Greve, University of Bergen, Zoological Museum, Museplass 3, N-5007 BergenUniv., Norway.INTRODUCTIONHackman (1980) listed eleven Bibio, one Dilophusand one Penthretria from Finland,Adult Bibionidae are common in many partsofNorway.
