thoumieu; and, in spite of the very conspicuous differences, is 
apparently more closely related to that genus than to any of the 
other genera included by Ashmead or to any of Cameron’s 
Oriental heresiarchine genera. In the apically rounded clypeus, 
the distinct sternauli, the straight first tergite, the exserted ovi- 
_positor, and the wing venation it is further allied to Stenodontus. 
The posteriorly and dorsally swollen head with very deeply con- 
cave ,occiput; the strongly dentate clypeus; the less-strongly 
convex face; the longer-jointed, compressed flagellum; the lack of 
areolation on the posterior half of the propodeum; the longer, 
slenderer legs; the very inconspicuous, basally located gastro- 
ceeli; and the highly ornamented body readily distinguish it from 
that genus. 
Female.—Head as broad behind eyes as at eyes, the temples 
convexly sloping, nearly as long anteroposteriorly as eye; occi- 
put almost semicircularly excavated, strongly and completely 
margined ; vertex strongly elevated above eye margins, declivous 
both before and behind, the upper margins of eyes and of poste- 
rior ocelli at the same level; cheeks rather weakly convex and, 
compared with the temples, narrow; frons not at all excavated; 
face weakly convex; eyes broadly reniform, parallel within; cly- 
peus distinctly separated from face, medially by elevation and 
laterally by deep oval fovez, broadly arched basally and rounded 
apically, the apex margined with a row of conspicous, uneven 
teeth; labrum not exserted; mandibles strongly curved, very 
acute; malar space practically obliterated; second joint of maxil- 
lary palpus triangular; antennz about three-fourths as long as 
body, incrassate and somewhat compressed beyond middle; scape 
robust, deeply emarginate, basal joints of flagellum slender. 
Thorax scarcely as wide as head; pronotum with upper margin 
Swollen laterally, epomia absent; notauli obsolete, being repre- 
sented anteriorly on each side by a small pit; scutellum large, 
flat, not at all elevated above level of mesoscutum; prepectus 
strong and complete; sternauli distinct for about half the length 
of the mesopleura; a broad, low, polished elevation below the 
wings; propodeum weakly and narrowly set off from postscu- 
tellum, gently curved from base to apex, with a broad shallow 
longitudinal groove from apex of areola to apex, only basal lateral 
areas and areola defined, the basal median area represented by 
@ single short median carina, spiracles small, about twice as 
wide as long; wings immaculate, areola trapezoidal, suboblique ; 
legs long, rather slender, hind metatarsus comprising about half 
of the tarsus, hind coxe with neither spine nor scopa beneath.
