about equal in length to the three preceding funicle joints, three- 

 jointed, the sutures between joints not very distinct; pronotuni 

 viewed from above triangiilar, slightly broader than long and faintly 

 lineolated; lateral lobes and anterior portion of median lobe of 

 mesoscutum weakly sculptured and shining, median lobe posteriorly 

 with sculpture similar to that of scutellum but not so strong; 

 scutellum and axillae opaque above, the perpendicular margins pol- 

 ished ; propodeum mostly polished ; wings rather slender and extend- 

 ing barely beyond the ajDex of abdomen; hind femora above between 

 middle and -base distinctly swollen; abdomen about equal in length 

 to the thorax exclusive of pronotum, broadly rounded at apex, 

 smooth at extreme base, reticulately rugulose beyond, the apical 

 tergites opaque; fourth tergite broadly emarginate at apex; oviposi- 

 tor barely exposed at tip. Head dark greenish-bronze in color; 

 thorax black with a metallic or aeneous tinge on mesoscutum and 

 pleura, the sutures and pleura more or less tinged with brownish; 

 antennal scape rufous, darker at apex ; pedicel and flagellum bronzy- 

 black ; legs all dark brown ; f orewing fuscous with the base hj-aline 

 to the apex of submarginal vein and a complete narrow transverse 

 curved hyaline band near the middle ; posterior wing entirely hya- 

 line; abdomen black with irregular broad whitish band at apex of 

 first segment; tip of ovipositor pale. 



Male. — Length 2.3 mm. Head, viewed from above, appearing 

 three times as broad as thick antero-posteriorly ; eyes hairy, lateral 

 ocelli very slightly less than the diameter of an ocellus from the eye 

 margin ; vertex slightly convex, not flattened ; viewed from in front 

 the head is slightly broader than high, the cheeks rounded ; antennae 

 inserted very slightly above the lower extremities of the eyes, well 

 separated at base; scrobes triangular and well defined, not deep; 

 scape short and moderately thick, not extending above the vertex; 

 pedicel small and subspherical ; flagellum long and thick, fully twice 

 as long as the height of head, nearly uniform in thickness through- 

 out, the base and apex slightly tapering; first funicle joint distinctly 

 more than twice as long as thick; second and third joints subequal 

 and about twice as long as thick; fourth joint hardly one and one-half 

 times as long as thick; fifth, sixth, and seventh, successively decreas- 

 ing in length, the seventh quadrate; club apparently solid, not thicker 

 than the funicle, bluntly pointed at apex, and equal in length to the 

 three funicle joints preceding it. Pronotum, mesoscutum, axillae, 

 and scutellum with nearly uniform shallow reticulate-punctate sculp- 

 ture, subopaque; propodeum shining, very faintly reticulate with a 

 weak carina at the middle; middle tibial spur subequal in length to 

 the first tarsal joint, slender; abdomen much narrower and shorter 

 than the thorax, smooth at base above, more or less faintly reticulate 

 elsewhere. Dull aeneous black with the head anteriorly and the
