NO. 2128. NEW GENERA OF MUSCOID FLIES— TOWN SEND. 621 



ually narrowing beyond middle. The intermediate abdominal seg- 

 ments have discals that are a little stronger than the closely-set 

 bristles covering the surface. The latter are a beginning stage of 

 the densely-set spines of abdomen in other forms. Cubitus without 

 wrinkle or stump. No facio-orbitals. Three postacrostichals and 

 four postsutm-als. Four strong lateral scutellar bristles. Abdomen 

 thickly hairy, also plem-ae and parafrontals. 



EUGAEDIA, new genus. 



Genotype. — Gaediopsis setosa Coquillett, Rev. Tach., 1897, p. 136. 



Differs from Gaediopsis as follows: Row of long strong bristles on 

 middle of parafacials. No ocellars. Facial ciha of equal strength. 

 Cheeks of male about two-fifths eye-height. Antennae and arista 

 about as in Chaetogaediopsis . Short discals on second and third ab- 

 dominal segments. No definite wrinkle at cubitus. Three posta- 

 crostichals and four postsuturals. Pleurae rather thickly hairy. 

 Hairs of abdomen not long, normal. 



OEDEMATOCERA, ne-w genus. 



Genotype. — Hypostena jiaveola Coquillett, Rev. Tach., 1897, p. 61. 



A remarkable form approaching Hypertrophocera in the heavily 

 enlarged third antennal joint of male. Proboscis is much reduced, 

 short; palpi small; mouth evidently subatrophied. Facial plate 

 greatly enlarged; facial depression very deep in male, the faciaha 

 and parafacials forming sharp ridges. Wings short and broad. Dis- 

 cal macrochaetae on second and third abdominal segments. The 

 genus possesses the facies of Leslcia, and may be distinguished there- 

 from by the above characters. The eggs are microtype, and the 

 reproductive characters are distinctly Salmaciid. (TD 4463.) 



PHYLLOPHOROCERA, new genus. 



Genotype. — Phorocera stemalis Coquillett, Proc. U. S. Nat. Mus., 

 vol. 25, 1902, pp. 111-112. 



Differs from the genotype of Phorocera (assimilis Fallen) as follows: 

 Hale. — Front at vertex fully one-third head-width, frontal bristles 

 in double row, frontalia broader behind, all the bristles of front 

 stout; cilia of facialia stronger and less closely placed, parafacials 

 much narrowed below, facial depression broadened in comparison 

 with facial width, the cheeks not over one-fourth eye-height; second 

 antennal joint scarcely elongate, the third enlarged and strongly 

 convex in profile on upper edge; arista thickened on basal three- 

 fifths, abruptly thin thereafter; palpi much thickened apically. Four 

 sternopleurals and four postsuturals; thoracic and abdominal 

 macrochaetae stronger and shorter, not mixed with long hair on 

 the abdomen but with many short bristles and some hair ventrally.
