NO. 2128. NEW GENERA OF MVSCOID FLIES— TOWNSEND. 625 



nearer to small crossvein. Third anteimal joint rather narrow, about 

 three times second. Proboscis beyond geniculation rather longer than 

 head-height, cm-ved strongly backward and upward at tip, subfleshy 

 but pointed apically. 



The genus is named in honor of Mrs. Annie Trumbull Slosson. 



EUCHAETOPHLEPS, new genus. 



GenotyjM.—ChaetopMeps polita Coquillett, Proc. U. S. Nat. Mus., 

 vol. 25, 1902, p. 107. 



Differs from CTmetopMe'ps as follows: No proclmate fronto-orbitals 

 in male. Male front averagmg no broader than one eye, very slightly 

 widening anteriorly, the face widenmg in same proportion. Para- 

 facials gradually narrowing below. Cheeks of male hardly one-sixth 

 eye-height. Apical cell narrowly open. Female unknown. 



UROPHYLLOPSIS, new genus. 



Genotype. — Admontia retiniae Coquillett, Rev. Tach., 1897, p. 54. 



Differs from ^^moTiim as follows: Facialia not ciliate. Parafacials 

 not broad, with practically only one row of very fine hairs, latter often 

 vestigial. Cheeks of female hardly over one-fourth eye-height. 

 Third antennal joint of female about three tunes as long as second. 

 Arista thickened on basal third. Basal aristal joints extremely short, 

 hardly distinguishable. Front tarsi of female not widened. Apical 

 cell closed in margin a httle before wingtip. 



TORTRICIOPHAGA, new genus. 



Genotype. — PseudomyotTiyria tortricis Coquillett, Journ. N. Y. Ent. 

 Soc, vol. 3, 1895, p. 55; referred to Hypostena, Rev. Tach., 1897, 



p. 60. 



Differs from VropJiyUopsis as follows: 



Female. — Front at vertex more than one-third head-width. Para- 

 frontals wider, parafacials bare, faciaha ciliate; third antennal joint 

 about two and one-half times second, arista thickened on nearly basal 

 half. Four sternopleurals, four postsuturals. Abdomen broad-ovate, 

 without median margmal pan- of bristles on first segment; thu-d seg- 

 ment with margmal row of 10 above, rather removed from margin; 

 anal segment with discal row of 10 and marginal row of 4 or 5; all 

 the macrochaetae erect and rather short. Apical cell with petiole 

 about two-fifths as long as hind crossvein, latter almost in middle 

 between cubitus and small crossvein.
