THE TRIBE CHALCIDINI — BURKS 347 



Description. — Pale yellow, with tan, brown, or black markings; 

 markings variable, vertex and occiput of head usually, three dorsal 

 marks on pronotum, broad band extending from apex of mesoscutel- 

 lum to anterior margin of mesopraescutum (fig. 10, /), isolated spot 

 on each lobe of mesoscutum, anterior and posterior margins of axillae, 

 faint markings on outer surface of metafemur (fig. 12, <?), and 

 usually transverse dorsal bands on gaster, tan, brown, or black. 



Female: 4.5-5 nun. Apex of antennal scape just attaining level 

 of posterior ocelli; ring segment one-fourth length of segment 4, 

 segments 4 to 10 equal, last three slightly shorter; scrobe cavity 

 shallow, edge carinate only at ventral margin; interantennal projec- 

 tion with a small carina, this carina usually extending up into scrobe 

 cavity nearly to anterior ocellus, sometimes somewhat shorter; frons 

 laterad of scrobe cavity uniformly covered with large shallow punc- 

 tures, area ventrad of antennal bases minutely shagreened ; width of 

 malar space one-quarter height of compound eye; combined widths 

 of compound eyes slightly greater than interocular space at level 

 of antennal bases; left mandible with two acute teeth, right with 

 three, dorsal one larger and blunt, two ventral ones small, acute, 

 their apices converging slightly; frontogenal suture curved; diameter 

 of posterior ocellus one-half width of interocellar space. 



Anterolateral angles of pronotum minutely carinate, anterior dorsal 

 margin acarinate; maximum length of mesopraescutum slightly less 

 than maximum width; parapsidal furrows partly obscured; axillae 

 each with a single row of setae near posterior margin; apex of 

 mesoscutellum provided with a minute lamina; metepisternum con- 

 spicuously punctured, setae inconspicuous; surface of metacoxa uni- 

 formly shagreened, without setae on outer dorsal side; metafemur 

 (fig. 12, o) rather narrow, not flattened on outer side, outer surface 

 sparsely provided with setae, ventral margin with 16 to 20 minute 

 teeth ; small inner tooth present ; apex of metatibia acute. 



Propodeum mostly smooth, minute mesal and apical carinae pres- 

 ent, lateral projections wanting; petiole three-fourths length of meta- 

 coxa, surface minutely shagreened, a sparse double row of long 

 setae present on either side, basal lamina narrow, not interrupted on 

 dorsal side, petiole markedly expanded in middle (fig. 13, h) ; gaster 

 acuminate, usually one-fourth longer than metafemur; abdominal 

 tergites 4 to 7 each with two or three transverse rows of setae ; cerci 

 oval, located midway between base and apex of epipygium; apex 

 of ovipositor sheath minutely roughened. 



Male: 3.5-^ mm. Antennal scape broad from base to apex (fig. 

 9, q) , apex of scape slightly exceeding level of posterior ocelli, meta- 

 femur with 16 to 18 outer ventral teeth, inner tooth sharp; petiole
