a synonym of Ma-siphya hrasiUana Braiier and Bergenstamm, which 

 species he phicod in Bioniyia. Aldrich (1925, pp. 108-109), however,

 species strictly congeneric with the genotype TacUnomyia rohusta 

 Town^end."

aethers necessary for identification. The type has not been seen, but 



Aldrich s description (unpublished notes) verbatim follows:
