Characters. — ■ Head round, flattened in front, placed low upon the thorax; front broad and 
high; eyes circular, somewhat bulging; ocelli three in number, the laterals large, closely contiguous to 
the eye margin, the middle one very small, placed in a groove on the front; palpi incurved, four jointed, 
the first joint small, the second somewhat thickened, the third longer than the second, the fourth longest; 
antennae 2 + 14 jointed, the first joint cylindrical, the second cupuliform, setose at the apex, the flagellar 
joints torus-like, closely sessile, somewhat compressed, nearly bare. Thora.x stout, oval, highly 
arched; mesonotum with short depressed hairs, setose only on the margin; scutellum semicircular, 
setae on the margin; metanotum arched. Abdomen clavate, compressed, constricted at the base, in the 
male six segmented, apical segment and forceps small, in the female six segmented, the ovipositor short, 
with two terminal lamellae. Legs strong, the fore legs short; coxas long and stout; all femora short, 
compressed, fore femora longer, middle subequal, hind pair shorter than the corresponding tibiae; tibis 
strong, almost clavate, all with lateral setae and long spurs. Wings longer than the abdomen, oval, with 
rounded base. Costa ends at some distance from the apex of the wing at the point where the radial 
sector enters the margin; subcostal vein very short, ending in Rj ; basal cell R long; media forks under 
or proximad of the basal section of the radial sector; cubitus forks far proximad of the base of the radial 
sector, the branches making a very acute angle with each other, but more divergent toward the margm ; 
anal fold strong, anal vein short, incomplete, delicate (PI. 6, Fig. 15).
