This paper deals with the Trinidad species included by C. H. T, Town send (Manual of Myiology, IV) in his tribe Masiphyiini. The evidence given supports the separation by Reinhard of the genus Siphosturmia Coc). and allies from Masiphya B. B. and allies. Four new species have been described in genera recognized by previous authors. Three new genera, each with a new species, have been described. Of these, one (Masiphyoidea) is certainly allied to Masiphya, but the affinities of the others (Pseudomasiphya and Mystacomyoidea) are open to doubt with the data available at present.
