The distinctive characters between the species in this genus, and 

 those in Hydrophoria, are somewhat diflicult to define ; the only posi- 

 tive point of difference being the comparative size of the scales of the 

 alulets, which are unequal in size, and larger in proportion, in Hydro- 

 phoria than in Hylemyia. Schiner has repudiated the genus Hydro-
