obscure shade as that of thorax and front, but with a silvery shade 

 in some lights; the pollen best defined on narrow base of second 

 segment, basal half of third, and all of anal segment. Legs brown- 

 ish, tibia? rufous. Wings distinctly smoky-yellow along the veins. 

 Tegulse smoky-yellowish, front scale slightly more whitish. 



Holotype, No. 19556 U.S.N. M. 



A male from Victoria, British Columbia, April 2, 1906 (E. M. 

 Anderson, through F. Kermode), measures 6 mm., wing 5.5 mm., 

 and differs in wings being clear, tegulai watery-whitish, pollen of 

 base of second abdominal segment broadening on sides, tibia? only 

 narrowly rufous on middle, and antenna? wholly deep black. It 

 may be a distinct species, but seems congeneric with the above 

 female. 



Family LarvcBVoridce. 



Okanagania new genus. 



Genotype — Okanagania hirta Townsend, new species. 



Differs from Ostracophyto as follows: Male. — Facial profile 

 deeply bent in, the epistoma very prominent. Facialia with thick 

 bunch of bristles just above vibriss^e, but otherwise bare. Eyes 

 thickly clothed with long hair. Parafacials bare, wide. Front at 

 vertex a little narrower than eye, much narrowed in middle, 

 widening still more anteriorly than at vertex, very prominent in 

 profile. Parafrontals broad anteriorly, with bristly hairs outside 

 the frontal row and long hair on \ertical and ocellar regions. 

 Occipito-orbital fringe very long, decreasing in length gradually 

 from the outer verticals. Vibrissa inserted w^ell above oral margin, 

 widely separated. Second antennal joint long; third broad, not 

 twice as long as second. Arista thickened on more than basal half, 

 first joint short, second joint elongate. Long apical decussate pair 

 of macrochaetse on scutellum; discal pair of straight bristles, with 

 several others approximating them in strength. Median marginal 

 and discal macrochaeta? on second and third segments, median and 

 lateral discal on fourth with marginal row, fourth and fifth rather 

 thickly covered with long hair besides the bristles. Thorax, 

 pleurae, scutellum, venter and legs also with long hair and bristles. 

 Claws elongate, about as long as last tarsal joint. Hypopygium 

 large. Apical cell narrowed at extremity, narrowly open, ending
