(Continued from page 165.) 
Genus Tricyphona Zctterstedt. 
Tricyphona protea, new species. 
General coloration pale yellowish brown; wings with the free 
portion of vein Ri very long, only a little shorter than the sector; 
cell Ri short-petiolate; cell Ist M2. open by the atrophy of m. 
Male. — Length 6.4 mm.; wing, 6.5 mm. 
Described from an alcoholic specimen. 
Rostrum and palpi pale; palpal segments nearly subequal, 
the fourth a little longer than the third and more ' slender. 
Antennae dark brown, the basal segments paler; flagellar segments 
oval, the terminal segment -not elongated. Head yellowish, 
darkest on the vertex. 
Thorax light yellowish brown without apparent darker stripes. 
Halteres short, pale, the knobs large. Legs with the coxcC and 
trochanters dull yellow; remainder of the legs broken. Wings 
a pale yellowish tinge; veins yellowish brown. Venation: Sci 
ending just before the fork of i?2+3; Sc2 some distance before 
the origin of the sector, this distance about equal to the basal 
deflection of Cu\; vein i?2 fused with R\ for a short distance back 
from the wing-margin, this fused portion about equal to r-m; 
petiola of cell Ri short, less than r-m\ cell 1st Mi open by the 
atrophy of m. 
Abdominal tergites dark brown, paler laterally; sternites dull 
yellow; apices of the segments darker brown; hypopygium dull 
yellow. 
Habitat. — Washington. 
Holotype. — cT, Mt. Rainier, Washington. 
In many respects this is a very remarkable fly, easily told 
from all its relatives by the great length of vein Ri before its 
fusion with R\. I have pointed out in another paper the reasons 
for changing the nomenclature of the radial \'eins in the Pediciini, 
this vein Ri having been hitherto considered as being the radial 
cross-vein.
