Front wing 2.25 to 6.5 mm. long; body punctures fine, moderately 

 close; combined face and clypeus strongly convex transversely, weak- 

 ly convex longitudinally, sloping forward from mouth to near antennal 

 sockets; upper edge of face produced between antennal sockets as a 

 short broad point which is bent backward a little between bases of 

 antennae; temple convex; back of head dropping vertically from hind 

 margin of hind ocelli to foramen magnum; occipital carina weak or 

 absent laterally, absent above and below; cheek about 1.1 as long 

 as basal width of mandible; mandible rather small, moderately wide 

 basally, the rest narrow; lower tooth of mandible much shorter than 

 upper tooth; apical edge of labrum protruding a little beyond clypeus; 

 flagellum rather short to long, filiform, slender to thick; upper part 

 of pronotum strongly swollen, rounded off to upper margin; pro- 

 pleurum weakly convex; scutellum weakly convex, without a lateral 

 carina; areolet absent; intercubitus separated from second recurrent 

 by about 0.75 its length; nervulus strongly postfurcal, usually by 

 about 0.6 its length; nervellus broken near its lower 0.3; prepectal 

 carina complete, ending dorsally at front end of subtegular ridge; 

 sternaulus broad, moderately long; metapleurum with a groove next 

 to pleural carina which contains a row of short hairs, otherwise polished 

 and impunctate except sometimes for a few hairs near its dorsal margin; 

 propodeum rather long, abruptly declivous at apical transverse carina, 

 with all carinae, except that usually the carina dividing median basal 

 area from areola is lacking and that in a few species the costula is also 

 lacking; propodeal spiracle usually elongate but sometimes subcircular; 

 legs stout to very stout; base of hind coxa projecting behind its socket 

 as a weak shoulder; second trochanter of front and middle legs fused 

 with its femur; spurs of middle tibia of approximately equal length; 

 tarsal claws pectinate or apparently simple; abdomen a little widened 

 medially; first tergite rather narrow basally, its spiracle near its 

 basal 0.35, its lateral longitudinal carina sharp, usually to the apex, 

 its median longitudinal carinae sharp basally, usually obsolescent 

 somewhere beyond the midlength of the tergite; epipleura of first two
