Genus Phyllolabis Osten Sacken. 
Phyllolabis latifolia, sp. n. 
General coloration light gray; wings pale gray, the stigma pale grayish brown; 
R2+3 shorter than R3 alone; cell 7st M2 short; male hypopygium yellow with the 
foliaceous appendage of the eighth sternite very broad and but indistinctly bifid at 
its tip. 
Male.—Length about 6.5 mm.; wing, 7.5 mm. 
Rostrum dark brown, heavily gray pruinose above; mouth-parts reddish brown; 
palpi dark brown. Antenne moderately elongate, dark brown throughout, the flagellar 
segments long-oval, provided with venticils that are but little shorter than the seg- 
ments. Head light gray with an indistinct black median line. 
Pronotum rather large, heavily light gray pruinose. Mesonotal prescutum 
brownish gray pruinose without distinct stripes; pseudosutural fovee black, short- 
triangular; tuberculate pits not evident; remainder of the mesonotum gray pruinose, 
the scutellum more brownish. Pleura clear light gray. Halteres pale. Legs with 
the coxe and trochanters pale brownish yellow; remainder of the legs dark brown, 
the bases of the femora paler. Wings pale gray; stigma rather indistinct, pale 
grayish brown; veins dark brown; Sc and the abortive vein behind Cu more yellowish. 
Venation similar to P. claviger but R2+3 shorter, less than R3 alone; veins R2 and R3 
more divergent, R2 at the wing-margin being distinctly closer to R7 than to R3; cell 
1st M2 shorter, especially the outer deflection of M3. 
Abdomen brown, sparsely gray pruinose. Hypopygium light yellow, including 
the pleurites and pleural appendages. Genitalia similar to P. claviger, differing as 
follows: outer angle of the pleurite much longer, projecting conspicuously beyond the 
pleural appendages; dorsal pleural appendage not slender and strongly bent at mid- 
length but very broad and flattened, roughly subtriangular with the base narrowest. 
Foliaceous appendage of the eighth sternite very broad and flattened, widest at the 
base, thence with the sides almost parallel slightly expanded at the distal end, the 
caudal margin of this leaf-like lobe slightly concave, feebly or indistinctly notched 
medially. 
Habitat.—Oregon. 
Holotype, 6, Forest Grove, March 28, 1919 (F. R. Cole). 
Genus Tricyphona Zetterstedt. 
Tricyphona sparsipuncta, sp. 0. 
Close to T. septentrionalis Bergr.; median prescutal stripe split by a pale line; 
wings subhyaline, the costal region more yellowish; r-m connecting R4+5 and M1+2. 
Female—Length, 7.5—8.8 mm.; wing 9.2—11 mm. 
Rostrum very short, transverse, dark brown, sparsely gray pruinose, the anterior 
margin with a row of a few long yellowish bristles; mouth-parts and palpi dark 
brown. Antenne dark brownish black, the basal four or five segments enlarged and 
very crowded as in this group of species. Head dark brown aboye, the front and a 
narrow margin around the eyes and across the anterior part of the vertex light gray. 
Mesonotum very high and gibbous. Mesonotal prescutum light grayish yellow, 
with three dark brownish stripes, the median stripe split by an indistinct pale capil-
