depression and the spiracular sulci nearly smooth and polished except 

 for some weak reticulation near the spiracles and occasionally some 

 subobsolete lines on the disk. The median depression on the propo- 

 demn is miusually shallow and mostly confined to the anterior half 

 of the propodeum, the posterior half of that sclerite having only a 

 very narrow crease or groove on each side of the median carina.

 green; thorax blackish, tinted more or less strongly with bluish green 

 on posterior margin of pronotum, posterior half of prescutum, scapulae,

 black; axillae strongly tmted with coppery; propodeum bluish green; 

 pleura black varied with green on mesepisternum ; all coxae and fe- 

 mora blackish, tinted with green; tibiae and tarsi reddish testaceous; 

 antenna] scape testaceous, darker toward apex; pedicel brownish; 

 flagellum black; mandibles dark reddish; wings hyaline, with a weak

 brown; abdomen black, the base beneath often more or less testaceous 

 and the fu-st tergite dorsally slightly greenish; ovipositor sheaths

 distance to apex. 



Head nearly imiformly heavily shagreened and moderately clothed 

 with whitish hairs. Eyes distinctly pilose; ocelli rather large, in a low

 malar space equal to approximately one-third height of eye; malar 

 groove present; anterior margin of face nearly straight. Antennal 

 scape subcylmdrical, nearly reaching to lower margin of anterior 

 ocellus; pedicel a little less than twice as long as broad;ringjointabout 

 two-thirds as broad as long; first funicular joint subequal m length to 

 pedicel but distinctly thicker, a little longer than broad; other joints 

 of funicle subquadrate and no thicker than first; club the same thick-

 combined. 



Thorax strongl}' shagreened and moderately hairy; parapsidal 

 gi'ooves sharply impressed; scutellum distinctly longer than broad, 

 with a distinct transverse furrow at apical one-third and carmately 

 margmed at apex, the groove setting oft' the apical carma foveolated 

 and not interrupted at middle; surface of scutellum behind cross 

 furrow distinctly reticulated, a little more weakly so medially than 

 laterally; mesepimeron smooth and bare, remainder of pleuron dis- 

 tinctly sculptm-ed and hairy; propodeum hairj^ laterally, bare medially; 

 spiracular sulci strongly foveated; all coxae and femora distinctly 

 sculptured, the median pair less strongly so than the others; tooth 

 on hind femur short, blmit, and located a little more than one-fiftli
