In the present instalment and in further parts und.er the same title I
expect to continue the review of the Tipulidae of Tropical Africa, .
placing particular stresson the rich .fauna of the Belgian Congo. At
the present time I am consideringespeciallyan interesting seriesof
theseflies that was taken by M. G. Menrrrn, Institut pour Ia Rech.erche
Scientifiqueen Afriqu'e Centrale,I.R.S.A.C.,
or Mont Muhi, Itombwe
North Kivu, during July 1955,I wish to €xpressmy thanks to the Chiefof the Entomological Section of the Musde Royal du Congo Belge,
Mr. P. Beslmwsrv for the loan of this collection.Types of the novelties
and representativesof the specieshave been returned to the MusdeRoyal du Congo Belge,at Tervuren.
