than wide, 2 and 3 subquadrate, 4 a little wider than iong, 6 distinctly wider than long; club 
not especially enlarged, the flagellum regularly clavate, the club a little less than half the 
length of the funicle; antenna 12-jointed, inserted at the clypeus. Frons very broad, the 
lateral ocelli their own diameter from the eye margins, the eyes somewhat longer than the 
cheeks. Fore wing with an oblique hairless line; marginal vein about thrice longer than wide, 
the postmarginal very short, about a third the length of the marginal, the stigmal a little 
longer than the marginal. A single line of coarser discal cilia proximad of the hairless line; 
marginal fringes very short. Mandibles with two rather stout, acute teeth. Head sublenticular,. 
the scrobes not long, the surface finely, transversely sheened but with scattered thimble 
punctures a line of which runs over the partially impunctate vertex along the eyes. Axille 
“joined acutely at the meson. Scutum and axille sculptured like the head but the punctures 
are rather numerous minute setigerous ones; scutellum glabrous. Metapleura with white 
pubescence; propodeum short at meson, with a median carina joined to the apex of scutellum,. 
widening laterad,and there with distinct transverse ruge (cephalo-laterad), otherwise glabrous. 
Abdomen pointed conic-ovate, a little longer than the rest of the body. Secutellum with sparse 
pubescence. Segments 3 and 6 of abdomen transverse, shorter than 2, 7 apparently occupying

Dark metallic blue, the abdomen purple, the scutellum green; wings hyaline; legs and 
antenne pale yellow (coxe not plainly seen). Antenne inserted near the mouth border, the 
serobes tolerably long, forming a triangle, the scape slender; pedicel metallic, bluish except at 
apex, twice longer than wide’ at apex, much longer than any of the funicle joints of which 
1-4 are subequal, each a little longer than wide, 5 and 6 longest, somewhat longer than wide 
and a little wider than the others; club slender, a little wider than the funicle and somewhat 
over half its length. Mandibles with the second tooth truncate, rather broad, its lateral 
apical angle subacute, the apex a little concaved. Axille widely separated. Marginal vein 
somewhat thickened, a little longer than wide, the postmarginal vein a little shorter than the 
marginal, the stigmal nearly twice longer than the marginal; oblique hairless line present. 
Frons narrow, the cephalic ocellus about its diameter (or a little less) from the eye margin; 
cheeks nearly as long as the eyes; frons not prominent but the face inflexed. Head with very 
fine surface sculpture and with a few very minute setigerous punctures. Seutum and axille 
like the head but the minute setigerous punctures rather numerous on the former. Scutellum: 
finely, densely punctulate or shagreened. Pronotum transverse. Proximal two segments of - 
abdomen greenish, scaly, the rest shining, the abdomen flat, pointed-ovate, as long as the thorax,. 
the ovipositor distinctly but very shortly extruded, white. Scutellum overhanging meson of
