SuBcGENUS RHAMPHOMYIA, s. sTR., FREY 
Characters. — Males nearly always holoptic, ocellar triangle and bristles evident; antenne 
not greatly lengthened. Body rather stout, acrostichals present, dorsocentrals in one or more rows. 
Pygidium usually small, half-open, penis usually thick and more or less hidden, rarely exposed and 
filiform. Legs rarely distinctly slender, usually rather robust, the hind femora of both sexes usually 
bearing bristles or spinules, sometimes in the females without bristles below and in the corresponding 
males with bristles only at base or middle, legs of females sometimes pennate. Axillar incision of 
wings acute, the alulz usually well developed. 
Type species : R. sulrala, Meigen. This group is well represented in palazarctic and nearctic 
regions. Dr. Frey notes (in litt.) « es ist auffallend, wie viele gelbbeinige RhamfAomyia-Arten in Nord- 
Amerika vorkommen; diese Arten sind wahrscheinlich àálter als die schwarzbeinigen Arten ». The 
following species can be assigned to this subgenus: R. albosegmentata, Zett., albina, Zett., amplipedis,
