Drosophila testacea von Roser, 1840, und D. limbata von Roser, 1840 werden wiederbeschrieben. 1. Introduction The collection of Diptera made by von Roser belongs to one of the oldest parts of the insect collections in the Naturkundemuseum Stuttgart. Due to the fact that von Roser published lists of the flies in his collection in a Journal which was not well known in his time, his descriptions of new species were mostly overlooked. In addition, the descriptions were extremely short and ambiguous. Most of the speci-mens were not originally labelled except for some type specimens. At some unknown time in the last Century printed labeis „Württemberg v. Roser" were added. Therefore the identification of type specimens is sometimes difficult. The first revision of the von Roser collection was made by Becker (1903) who recognised most of the species described by von Roser. Further revisions of the Drosophilidae were made by Duda and Basden. Duda integrated his findings in several publications, especially in the Drosophilidae section of Lindner's „Fliegen der palaearktischen Region" (1934/35). Some years ago the late E. B. Basden en-trusted me with notes and drawings made by him during his revision of the von
