l)in(.'d. Maiulililcs rather small, short and thick, tridentate at apex, with 

 the lower tootli acute and rather long, the other two less acute and sep- 

 arated by a shallow eniargination. ^Maxillary palpi four-jointed, the 

 first three joints subequal, the first very slender at base, the fourth 

 about twice as long as the third and triangular ; labial palpi with three 

 short joints, the first longest, the second shortest. 



Thorax rather robust, convex above ; pronotum and mesoscutum of 

 usual shape ; axillae short, transverse and acutely meeting or nearly so ; 

 scutellum rather large and acutely rounded at apex, strongly elevated 

 and depressed on the disk, the sides abruptly declivous towards the base 

 and more convex towards the apex'; propodeum short at the middle, 

 but lengthening towards the sides ; metapleura not very large but reach- 

 ing to the hind coxae, the metepimeron visible as a narrow sclerite 

 between the meso- and metapleura ; prepectal plates strongly chitinized 

 and separated below from the mesopleura by a narrow sclerite which is 

 l)robably a part of the mesosternum. 



Abdomen triangular, strongly depressed, hardly more than half as 

 long as the thorax; the vibrissal plates located shout one-half way be- 

 tween the base and middle; the fifth ventrite not compressed but pro- 

 duced after death beyond the apex of the dorsum and enclosing the base 

 of the ovipositor; protruded portion of the latter nearly as long as the 

 abdomen, the sheaths slender and terete. 



Wings with uniform discal ciliation, the marginal fringe short, the 

 speculum distinct and wider below ; costal cell rather wide ; marginal 

 vein about twice as long as thick, the stigmal about a third longer, the 

 postmarginal a little longer than the stigmal ; hind wings with the costal 

 cell narrow throughout but reaching to the booklets. Legs moderately 

 long and slender ; the middle tarsi with well developed spines on the 

 plantar surface, the tibial spur as long as tiic first tarsal joint: hind 

 tibiae with two apical spurs of which the inner is much the longer. 



Sculpture very finely reticulate ; the frontovertex with four rows of 

 small punctures, the mesonotum including scutellum with numerous, mi- 

 nute setigerous punctures ; scutellum more coarsely reticulate but becom- 

 ing smoother and somewhat polished on the sides and apex; basal tergite 

 of abdomen about as coarsely reticulate as the .scutellum. 



Eyes with a very fine, short pubescence ; mesonotal pubescence rather 

 long and bristle-like but not con,spicuous ; propodeum and metapleura 

 bare except for a few whitish, fine hairs just behind and laterad of the 

 spiracles; abdomen rather coarsely pubescent, the apex of the lr:St ter- 

 gite with a double row of moderately long bristle-like hairs ; the ovi- 

 positor sheaths finely pubescent. 



Coloration metallic black. 



Male: Similar to tjie lem;de with the head thinner and wider, the 

 eyes smaller and more oval; the frontovertex much wider or as wide 

 as long; the ocelli considerably larger, arranged in an equilateral tri- 

 angle, the posterior pair touching the eye-margins and less than half their 

 diameter from the occipital margin ; scrobes converging, nearly meeting.
