treestumps and near fallen timber, and onespecimen has been reared from a pupa foundunder oak (Quercus) bark in April (Chandler,1975). Chandler (1975) and AlIen(1983) both mention localities of older forest- mixed woodland and older park area.M. dolium has been recorded once earlierfrom Norway as Lissa loxocerina Fallen bySiebke (1877). It was found in the botanicalgarden at T0yen in Oslo August 1st. 1847.The specimen, a female, is present in ZoologicalMuseum of Oslo. In the Zoological Museumof Oslo one additional specimen, a malecollected by Esmark and labelled «Oslo»only, was found. This is the only material inNorwegian museums. The name M. loxocerinaFallen 1829 was synonymized by Hennig(1941) in his revision of the Megamerinidae.Lyneborg (1962) reports M. dolium as distributedall over Denmark, but not common.In Sweden it is a southern species distributednorth to the provinces Bohuslan, Vastergotland,Oland and Gotland (Ringdahl 1960).Waiter Hackman (pers. comm.) has informedus that M. dolium is distributed in SW-Finland,and that it is a rare species there.M. dolium is probably a rare fly also inNorway. It is doubtful that the Botanical gardentoday can sustain populations of fliesdeveloping in rotten wood or fallen timber. Itis noteworthy that in a survey of anotherisland, Ost0ya, in the inner Oslofjord withMalaise-traps, window-traps and netting duringthe years 1982 to 1984, no specimenswere found even though localities should besuitable for M. dolium. Parts ofouter Vestfoldhave also been surveyed during the last years,but no specimens of this species have beenfound.ACKNOWLEDGEMENTSWe are most grateful to the following peoplefor information on the distribution of M. dolium:A.A. AlIen, London (England), W.Hackman, Helsingfors (Finland) and U.Qvick, Eskilstuna (Sweden).REFERENCESAlIen, A.A. 1983. Further notable Diptera fromWindsor forest. Ent. Rec. J.
