4. Mid femur with one or more prominent bristles on distal half of antero ventral surface; 

 fore tibia with three dorsal and three posterior bristles; mid femur with an uninterrupted 



row of bristles on anterior surface spinosissima Mall. 



Mid femur with only setulae on distal half of anteroventral surface; fore tibia with one or 

 two bristles on dorsal and posterior surfaces; mid femur with an interrupted row of

Pogonomyza campestris sp. nov. 



Female. — Black species, shining. Head black; parafrontals, parafacials, and cheeks, 

 silvery gray pruinose, with blackish reflections. Frontal vitta black, opaque. Antennae, 

 palpi, and proboscis, black. Thorax blackish, with brownish gray pollen, subshining. 

 Abdomen piceous, polished, shining, with no trace of pollen. Legs black, subshining. Pul- 

 vilU fuscous. Wings yellowish; veins yellow. Calyptrae whitish, tinged. Halteres yellow. 



Eyes separated by a distance slightly less than one-third width of head. Frontal vitta 

 nearly equal in breadth to length of third antennal segment; sides subparallel; cruciate bristles 

 well developed; parafrontals with a few accessory setulae on posterior half. Para- 

 facials and cheeks narrow. Antennae short, equal in length to distance between vibrissae; 

 vibrissae strong and long; arista with short pubescence. Thorax with irregularly paired 

 acrostical bristles, between which are numerous setulae. Pra two-thirds as long as the 

 following bristle; posthumeral bristle not duplicated. Sternopleural bristles, 1 : 2, with an 

 additional weaker anterior bristle below. Abdomen broadly subovoid; tergum 4 with strong, 

 erect, marginal bristles; terga 2, 3, and 5 with weaker, appressed, marginal bristles; terga 

 4 and 5 with a transverse series of strong, erect, discal bristles on dorsum; tergum 3 with only 

 lateral discal bristles present on dorsum. Fore tibia with one weak anterodorsal, one median 

 dorsal, and one posterior bristle. Mid femur with a continuous row of bristles on anterior 

 surface, the anteroventral surface bare, and the posteroventral surface with three bristles 

 along proximal half; mid tibia with one anterodorsal, one posterodorsal, and three posterior 

 bristles. Hind femur with a row of bristles for almost the entire length of anteroventral sur- 

 face; posteroventral surface with four bristles along proximal half, besides the usual apical 

 bristles; hind tibia with five anteroventral, five anterodorsal, and three or four postero- 

 dorsal bristles, and a postero- and an anteroventral apical bristle. Costal thorn prominent; 

 m-cu cross-vein erect. Upper calyptra covering the lower. Length, 5.5 mm. 



Locality. — 1 9 , Montezuma Marshes, Cayuga, New York, June 1, 1920. 

 Type. — In author's collection. 



Pogonomyza campestris differs from P. prohoscidal s, the species which 

 it most closely resembles, in the length of the prealar bristle, the normal 

 thickness of the mid femora, and the polished appearance of the abdomen.
