NO. 2018. SYNOPSIS OF GENERA OF AGROMYZIDM—MALLOCH. 145 



which extend above the level of the epistome, I consider its position 

 in the Milichin^ more nearly the correct one than if it were retained 

 in the Agromyzinae. 



HEMEROMYIA OBSCURA Coquillett. 

 Hemeromyia obscura Coquillett, Joum. N. Y. Ent. Soc, vol. 10, 1902, p. 190. 



Female. — Shining black, anterior margin of frons narrowly, face 

 and cheeks, third joint of antennaa on lower half and tarsi yellow. 

 Halteres with milky- white knobs. 



Frons one-third as wide as head at anterior margin, at posterior 

 ocelli one-half as wide as head; surface of frons granulose; ocellar 

 triangle glossy, distinct; center stripe opaque, bare except for the 

 pair of bristles on anterior margin; orbits glossy on upper half, four 

 bristles present; antennae small, haK hidden below the anterior mar- 

 gin of frons, which is slightly protuberant, third joint rounded, cov- 

 ered with very short, white pile; arista swollen at base, bare, its 

 length short of the breadth of frons at anterior margin; face concave; 

 cheeks higher posteriorly than anteriorly, the shape much as in 

 Meoneura, but the bristles much weaker on the diagonal ridge, the 

 upper bristle, in front, midway between the apex of antennas and 

 lower margin of cheek, and in line with lower margin of eye ; proboscis 

 fleshy (palpi retracted); occiput invisible on upper half. Mesono- 

 tum with surface finely granulose; four pairs of dorso-centrals, no 

 other setulae on center of disk ; mesopleura and sternopleura with 2-3 

 bristles each; scutellum as disk of mesonotum, the basal pair of 

 bristles weaker than the apical pair. Abdomen with dorsum bare, 

 the setulae confined to the lateral margins and the apex. Legs with 

 femora slightly thickened, fore femur with 2-3 long bristles on apical 

 half of postero-vertical surface, and a row of shorter ones from these 

 to base; other femora with shorter bristles on ventral surfaces; no 

 tibial bristles present; apical spurs weak. Wings clear, veins black- 

 brown; inner cross vein at near to wing middle, at distinctly beyond 

 end of first vein, and at about one-third from apex of discal cell; 

 outer cross vein at slightly more than its own length from inner, and 

 about same length from end of fifth vein; third and fourth veins 

 subparallel on last sections; sixth vein very distinct, but not reaching 

 wing margin. 



Length. — 1.5 mm. 



Redescribed from type-specimens. 



Locality. — Las Vegas, Hot Springs, New Mexico (H. S. Barber). 

 I have also seen two specimens taken by Mitchell and Cushman on 

 Chisos Mountains, Brewster County, Texas, June, 1908.
