This species has been taken in widely separated spots in eastern 

 United States and at Antioch, Calif. Most of the localities from 

 which it is known are coastal, and it is suspected that the character- 

 istic habitat is coarse marsh grass.

Front wing 4.7 to 8.0 mm. long; clypeus rather short, rather weakly 

 convex, with a very weak, blunt, median apical tooth, but the tooth 

 appearing to be rather strong because apical part of clypeus is im- 

 pressed on each side of it; temple full, strongly convex; tyloids linear, 

 sharp, moderately strong, extending about 5 segments; mesoscutum 

 mat marginally and near notauh, the rest subpolished, its punctures 

 small, weak, separated by about 1.5 then* diameter; mesopleurum 

 polished, with moderate-sized punctures that are separated by about 

 1.5 their diameter, but on much of median part of mesopleurum the 

 punctures obscured by \vrinkhng; first tergite exceptionally short; 

 second tergite of male moderately mat, with small weak punctures 

 that are separated by about 2.5 their diameter; second tergite of fe- 

 male subpoUshed, with fine, weak, very sparse punctures; ovipositor 

 sheath about 0.37 as long as front wing; ovipositor strongly com- 

 pressed, its tip as in figure 327, j. 



Black. Palpi and tegula* fuscous or black; front and middle legs 

 beyond first trochanters ferruginous, the apex of their fifth tarsal 

 segments brownish; hind second trochanter, femur, and tibia ferrugi- 

 nous, the apical 0.12 ± of the femur and tibia infuscate; hind tarsus 

 ferruginous brown or fuscous, each segment a little paler at the base; 

 wings faintly infuscate; extreme apex of male first tergite and apical 

 0.3 ± of female first tergite ferruginous; second and third tergites
