Female: Black except for yellow fore- and midtibiae, extremities 

 of hindtibiae and all femora, scape of antenna, and wing veins. Aver- 

 age in length 3.4 mm. (3.2-3.8). Abdomen globular and plump with 

 only slight lateral compression; sixth tergum about V/i times the 

 length of the fifth; sculpturing of fine, shallow punctations covers 

 all of lateral surface of sixth tergum and extends over dorsal sur- 

 face on anterior half; covers most of lateral and dorsal surfaces of 

 all other abdominal terga; ninth tergum short and stubby, averaging 

 .14 mm. (.12-. 17) in length. Internal genitaha with broad dorsal 

 valves for horizontal length and their color is black; very little dorsal 

 extension ateriorly, of dorsal and ventral valves, so that stylet arch 

 is close to a horizontal plane; average length of genitaha 1.5 mm. and 

 average height .75 mm. ; thus height is about half of length. Propo-

 and on middle of hindfemora. Wing veins linear; marginal slightly 

 longer than postmarginal; marginal averages .30 mm. (.25-. 37) and 

 postmarginal averages .25 mm. (.17-. 30); stigmal club rectangular.
