THE TRIBE CHALCIDINI — BURKS 273 



one-third height of compound eye; frontogenal suture extending 

 transversely from compound eye to dorsal articulation of mandible; 

 combined widths of compound eyes one-half greater than width of 

 interocular space at level of antennal bases; diameter of posterior 

 ocellus one-half interocellar width. 



Dorsum of thorax coarsely punctured, anterolateral angles of pro- 

 notum strongly carinate, almost laminate, anterior dorsal margin 

 with carina interrupted on mesal one-quarter; parapsidal furrows 

 partly obliterated; prepectus entirely concealed by a hooklike projec- 

 tion of anterodorsal angle of mesoscutum; mesoscutellum bidentate 

 at apex, these projections small, upturned, usually acutely pointed; 

 metepisternum conspicuously pitted, densely covered by long setae; 

 metacoxae glabrous, setose except on outer dorsal side; metafemora 

 (fig. 12, c) glabrous, rather sparsely covered by short pubescence, 

 semiglobose, outer ventral basal tooth one-fourth to one-third size 

 of following teeth, second and third teeth long, slender, slightly 

 curved, apical tooth large, blunt; inner tooth wanting; metatibia 

 with apex long, sharp, slightly curved. 



Propodeum sparsely covered by long pubescence, conspicuously 

 carinate; two lateral teeth present on either side, one rather blunt, 

 upturned, located at each posterolateral angle, others on either side 

 of insertion of petiole, spiracular openings nearly vertical; petiole 

 glabrous, slightly less than three times as long as wide at widest 

 point, several long setae present on each lateral margin near base, 

 lateral carinae lacking, basal lamina broad on ventral side, indis- 

 tinct or wanting on dorsal side; gaster shorter than metafemur; 

 abdominal tergites 3 to 7 with sparse lateral setae ; eighth tergite very 

 faintly reticulated, sparsely covered by short setae; spiracular open- 

 ings with anterior margins straight ; cerci oval, located near anterior 

 margin of epipygium ; apices of ovipositor sheaths provided with long 

 setae on ventral side. 



Male: 4.5-5 mm. Antennal scape (fig. 8, j) slightly broader at 

 apex than base ; combined widths of compound eyes one-third greater 

 than interocular space at level of antennal bases; inner tooth of 

 metafemur wanting; petiole three times as long as wide.

 dorsata (Cresson) only in being red instead of yellow.
