margin of wing; whole surface of wing distacl of the upward curve in 

 submarghial vein densely ciliated; marginal cilia very short. 



Anterior femur distinctly swollen, broadest between middle and 

 apex ; anterior tibia moderately stout and shorter than femur ; middle 

 tibia with three short, blunt spines on outer apical margin, the calcar- 

 ium a little shorter than basitarsus; basitarsus and two following tar- 

 sal segments of middle legs each with a double row of stiff spines 

 beneath; posterior coxa densely clothed with short white pile; pos- 

 terior femur moderately broad, a little broader beyond than before 

 the middle, and with its apical one-third weakly margined beneath 

 by a very narrow flange: hind tibia strongly compressed, not quite so 

 broad as femur, its posterior margin sharp; basal segment of pos- 

 terior tarsus about as long as two following segments combined. 



Abdomen as long as thorax and slightly narrower, weekly sculp- 

 tured, its apex rounded; ovipositor sheaths exsertcd about one-third 

 the length of abdomen. 



Male. — Length 2.1 mm. Color in large part testaceous, the vertex, 

 broad stripe along inner orbits, mesoscutum except broad lateral 

 margins, entire scutellum, and dorsal angles of axillae dark metallic 

 green or aeneous; frons medially, cheeks, most of propodeum, and 

 mesosternum more or less tinged with metallic or brassy ; dorsum of 

 abdomen, except at base and apex, dark brown; antennal flagellum 

 blackish; legs concolorous with sides of thorax, only the hind legs( 

 sometimes a little brownish ; wings hyaline. Pubescence pale, short, 

 and moderately dense, on dorsum of thorax, longer on inner orbits 

 and propodeum. 



Head strongly transverse, broadly but not deeply concave beliind, 

 almost perpendicularly truncate behind vertex ; lateral ocellus a little 

 less than its diameter in front of sharp posterior margin of head and 

 about equally distant from the eye margin; ocellar triangle obtuse, 

 the postocellar line about twice as long as line from lateral ocellus to 

 front ocellus ; anterior margin of frons not forming a sharp ledge at 

 its junction with malar space but with a trace of this ledge; malar 

 space equal to about half the vertical length of eye ; eye weakly pubes- 

 cent; antenna inserted below a line connecting lower extremities of 

 eyes; scape cylindrical, not quite attaining level of front ocellus; 

 pedicel about twice as long as broad; ring joint transverse; first funic- 

 ular segment about as long as pedicel; last funicular segment sub- 

 quadrate ; club a little longer than two preceding segments combined, 

 obliquely truncate. Mesoscutum convex, with fine reticulate-punctate 

 sculpture above, more weakly reticulated laterally ; parapsidal grooves 

 traceable but not deeply impressed ; scutellum convex, with very fine 

 reticulate-punctate sculpture giving an almost granular appearance; 

 axillae narrowly separated, the dorsal portion with sculpture like that
