Bright metallic greenish blue, the knees, tibiz and tarsi yellowish brown, the tarsi 
paler, the first eight joints of the antenna dusky, the rest black; scutellum distad of transverse 
suture and the postscutellum polished. Scutum finely, transversely lineolated, longitudinally 
so distad, the scutellum finely, polygonally scaly, also the axille. The abdomen polished. 
Habitat: Babinda, Queensland. Jungle (500 feet), October 28, 1911.

TOMICOBIELLA new genus. 
Female:—Head small, triangular, the antenne inserted at the mouth border, filiform, 
8-joited without a ring-joint, the club solid; scape long and slender, the club also long, 
cylindrical but a little less than two thirds the length of the scape; funicle joints about twice 
longer than wide, a little less than half the length of the club. Mandibles 4-dentate. Pedicel 
somewhat longer than funicle 1. Hind femur short, compressed, unarmed; hind tibial spurs 
double, short and stout. Cephalic femur very slightly enlarged, simple. Marginal vein short 
(as in the Eurytomide), only about four times longer than wide, much less than a third the 
length of the submarginal, subequal to the stigmal, the postmarginal vein practically obsolete. 
Pronotum distinct, transverse; scutum wider than long, the parapsidal furrows moderately 
delicate, complete. Scutellum simple but its distal margin indented. Axille widely separated. 
Postscutellum a transverse row of fovew. Propodeum transverse-linear, broadening a little 
laterad, foveate, mesad prolonged into a thick petiole-like projection to which is attached 
the abdomen. The latter thus appears to be stoutly petiolate. Second segment of abdomen 
(which is ovate) occupying fully somewhat over two thirds the surface, its caudal margin 
‘straight. Ovipositor just tipping abdomen at apex. Fore wings with short marginal fringes, 
the discal ciliation normal. Mesepisternum large, indented. A short tuft of hairs from base 
of abdomen on each side of meson. 
1. TOMICOBIELLA SUBCYANEA new species. 
Female :—Length, 1.30 mm. Tolerably stout. 
Very dark metallic blue-black, the wings hyaline, the legs brown except cephalic coxa 
and femur which are concolorous; rest of cephalic leg white. Antenne brown, the distal third 
of club black. Funicles 3 and 4 somewhat the longest of the funicle; 1, 2 and 5 subequal. 
Club a little wider than the slender funicle, thrice longer than its width. Second abdominal 
segment, axille and caudal margin of pronotum glabrous. Thorax scaly reticulated and with 
scattered thimble punctures which bear solitary, long black sete. ‘‘ Petiole’’ with a few 
longitudinal ruge, one of which is median, the surface densely sculptured. Axille with two 
rather large fovee caudad. Abdomen dark blue.

Eright metallic green with eneous tinges (especially axilla, centres of seutum and
