Syrphidae from Suriname

This study is intended as a continuation of the “Preliminary List of Syrphidae” published in volume V of this journal. As no further information on the Syrphid flies of the other Guianas has come to my knowledge these countries can be left out of consideration here. Since the dispatch of the manuscript of the “Preliminary List” to the editors several species not yet known from Suriname have been received. Once again a large part of these flies were collected by my son Drs. P. H. van Doesburg junior. Dr. D. C. Geijskes, Director of the Suriname Museum, Paramaribo, has also sent me big lots of Syrphids in which many interesting species were represented. To both gentlemen I wish to express heartfelt appreciation. Moreover my son deserves special thanks for interrupting his own demanding work to produce the beautiful, exact illustrations.
