OSTRACOPHYTO new genus. 



Genotype, Ostracophyto aristalis Townsend new species. 



Dififers from Mctaphyto (genotype, genalis Coqtiillett) as follows: 

 Female front at vertex hardly more than one third head width ; 

 frontal, vertical and orbital bristles much stronger, also ocellar 

 bristles; second antennal joint short, first and second aristal joints 

 elongate, arista thickened nearly to tip which is strong and sharp- 

 pointed; palpi shorter and more slender, a little widened at tip; 

 frontal bristles descending as low as base of arista, closely placed. 

 Abdomen with strong median discal and marginal bristles on inter- 

 mediate segments, anal segment with discal and marginal rows. 

 Apical cell short petiolate, hind crossvein strongly sinuate. 



Ostracophyto aristalis new species. 



Length of body, 8 to lo mm.; of wing, 7 to 9 mm. Two females, Wood- 

 side, California, April 25, 1906; Santa Clara county, California, April, 1902 

 (Coleman). 



Black, rather shining. Face and front silvery pollinose, the parafrontals 

 showing largely blackish throvigh the pollen, which here has a faint brassy 

 tinge. Frontalia dark brown, first two antennal joints slightly rufous, arista 

 soft black. Palpi yellowish, their bases fuscovis. Thorax and abdomen thinly 

 and irregularly silvery pollinose ; four equal deep black vittse on thorax ; scu-

Holotype, No. 19570 U. S. N. M. 



The holotype, which is the Woodside specimen, was labeled by 

 Coquillett " Mctaphyto aristalis Coq.," but I can not find that the spe- 

 cies was ever published. 



UPODEMOCERA new genus. 



Genotype, Upodemocera rohinsoni Townsend new species. 



Differs from FahricieUa as follows : Male. — Front at vertex nearly 

 or quite as wide as one eye. Profile of third antennal joint like that 

 of a shoe, the upper apical corner being greatly prolonged into an 

 angle and the lower edge at the same time bulged strongly. First 

 aristal joint very elongate, second twice as long as first and fully half 

 as long as last joint. Hypopygium massive, much larger. Lobes of
