long; club three-jointed, a little broader than the funicle, and not 

 quite equal in length to the three preceding funicle joints combined, 

 the basal joint subquadrate; second joint as long as the basal; third joint 

 conical; ocelli in a very low triangle, the postocellar line more than 

 twice the length of the ocellocular line; occiput immargined above, 

 cheeks margined posteriorly; dorsal portion of pronotum very nearly 

 as broad as the mesonotum and distinctly shorter than the mesoscutum ; 

 mesepistemum granularly rugulose, the mesepimeron indistinctly, 

 longitudinally striate; propodeum very nearly perpendicular to the 

 apex of scutellum, broadly but very shallowly impressed medially, the 

 impressed area granularly rugulose; remainder of propodeum more 

 coarsely rugose; marginal and postmarginal veins practically equal, 

 the stigmal about three-fourths the marginal; abdominal petiole nearly 

 twice as long as the hind coxae, rather slender, flattened and nearb' 

 smooth above, longitudinally striate at sides and beneath, and joinin,; 

 the main part of abdomen ventrally, or, at least, at the antero-ventr ,1 

 angle; body of abdomen subglobose and ending in a short sharp pc''c, 

 strongly compressed from the sides, very strongly arched above ;e 

 attachment of petiole as viewed from the sides, a little longer than e 

 head and thorax combined and viewed laterally not one-third lo <^x 

 than thick dorso- ventrally ; fifth segment the largest, approximr ?ly 

 twice the length of fourth on the median dorsal line ; ovipositor slig ^\y 

 exposed at tip; hind coxse granularly rugulose like the middle of 

 propodeum. Black; flagellum dark brown; scape brownish testaceous; 

 coxae and femora black ; apices of femora and all tibiae yellowish brown ; 

 all tarsi pale yellowish, claws brown; wings hyaline, venation brownish. 



Male. Length 1.35 mm. Scape somewhat swollen beneath, reach- 

 ing to the front ocellus ; pedicel globose ; between pedicel and first funicle 

 one small ring-joint; funicle five-jointed, the joints, except the fifth, 

 narrowed at apex into a distinct neck, each joint about twice as long as 

 the thickened portion is thick and bearing hairs about twice as long as 

 the length of segment; neck on apex of first segment shorter than on 

 the other segments and the thickened portion longer; fifth segment not 

 narrowed at apex, about twice as long as thick, with the hairs shorter 

 than on the other segments; between each of joints two, three, four, and 

 five of the funicle is what appears to be a very small transverse ring- 

 joint, (visible only in balsam-mounted specimens) ; club two-jointed, the 

 joints subequal in length, the apical joint ending in a very short incon- 

 spicuous nipple-like point; the propodeum is usually nearly uniformly 

 reticulately rugose all over, the sculpture of the depressed area not 

 markedly different from the rest of the surface; abdominal petiole 

 longer than the hind coxae, but not twice as long, slender, and weakly 

 shagreened, not striate; body of abdomen small globose, hardly more 

 than half as long as the thorax. Otherwise similar to the female, but 

 with all tibiae mostly blackish -brown.
