1908] JOHNSON — DIPTERA OF THE BAHAMAS 69 THE DIPTERA OF THE BAHAMAS, WITH NOTES AND DE-SCRIPTION OF ONE NEW SPECIES. BY CHARLES W. JOHNSON. The following Diptera were mostly collected by Messrs. Thomas Barbour, Glover M. Allen and Owen Bryant during their trip to the Bahamas in the summer of 1904. The specimens from Mangrove Cay, Andros, were collected by Mr. Bryant, who visited the island after Messrs. Barbour and Allen had returned to the United States. This collection probably represents but a small percentage of the actual number to be found; it is however practically our first knowledge of the dipterous fauna of these islands, as only eight species have previously been recorded. The diptera of the West Indies have been, for the most part, studied somewhat superficially, owing to the limited amount of material that has been collected. The only exception to this is the island of St. Vincent, where Mr. H. H. Smith made a very extensive col-lection, which has been studied by Professors Williston and Aldrich,^ who record upwards of 350 species. The combined lists of Boeder ^ and of Coquillett ^ gives 193 species from Porto Rico. The writer in 1894^ recorded 115 species from Ja-maica, since that time about fifty species have been added to the list. The number of species recorded from Cuba is about 250. The species previously recorded have also been included, and the following list of over ninety species represent all that are known to occur on the islands up to the present time. Psychodidae.
