(1) Faunistic insect collecting was done in Suriname from September 1963 to December 1964 with two types of “malaise” traps. (2) Trapping was practised on nine localities in different habitats, operating from the seacoast near Paramaribo via the older coastal belt and the savanna region into the rainforest of the hilly interior. (3) During this operation, a total of about 90.000 insects was collected. There was but little variation in the proportions of the different orders of insects taken in the nine localities. This is explained by the mode of sampling. (4) The catches show the following relative abundance: Diptera 1/2, Hymenoptera 1/5, Lepidoptera 1/7, Coleoptera 1/20, Hemiptera 1/40, Orthoptera 1/50, others less than one percent. (5) The variation within the orders was: Diptera 36—72%, Hymenoptera 11—33%, Lepidoptera 8—37%, Coleoptera 1—11%, Hemiptera 1/2—9% and Orthoptera 1—4%. (6) Most of the collected insects belong to dayfliers, i.e.: Diptera, most of the Hymenoptera (Aculeata), Lepidoptera Rhopalocera and Odonata. Other species collected are active at night. The moths and micro’s were represented 10 times as many as the Rhopalocera, but the Nematocera formed only 1/6 of the Diptera. Among the flies 1/5 belonged to the Tabanidae.
