and mandibles reddish brown. Head circularly striate, the mandibles as in Orasema. Thorax 
uniformly rugoso-punctate, the scutellum obtuse at apex. Parapsidal furrows complete, 
punctate. Dorsum of thorax plane. Abdomen large, compressed, upturned, the petiole some- 
what longer than the hind coxa. Metatarsus slender. Scape somewhat shorter than funicle 1, 
distinctly longer than wide, the pedicel short, wider than long; funicle 1 longest of the 
antenne, widening distad, one and a half times longer than wide at apex, or that many times 
longer than funicle 2, which with the following joints are no longer than wide at apex, 
narrower at base, becoming smaller toward apex, the simple club joint a little longer than 
funicle 2 (in one antenna the distal funicle joint was fused with the club); funicle joints armed 
around apex with several short, nipple-like tubercles. Antenne 11-jointed, no ring-joint.

Habitat: Port Darwin, Northern Territory. 
Type: No. Hy 3282, Queensland Museum, Brisbane, the female on a tag; head on a slide. 
GENUS EPIMETAGEA Girault. 
Synonym: Astilbula Girault. 
The same as Metagea Kirby but the antennze not moniliform and only 10-jointed. 
Also agreeing somewhat with Pseudochalcura Ashmead but differing again in lacking one 
antennal joint. Head thin, triangular, the antennz inserted slightly below the middle of the 
face, the club solid and ovate, longer than any of the funicle joints but slightly shorter than 
the simple cylindrical scape; pedicel obconic, short, subequal to joint 4 of the funicle, bearing 
from one side of its apical margin a single, very long, slender but stiff bristle-like seta which 
reaches distad nearly to the apex of joint 3 of the funicle. Proximal funicle joint longest, 
nearly twice the length of the pedicel, all the funicle joints obconic, widening distinctly 
distad, all more or less prolonged obtusely from one apical corner, the distal joints more so. 
None of the joints petiolate or subpetiolate; no ring-joint. Mandibles long and falcate, acute 
at apex, the right with two large triangular teeth within, the left with one that is larger 
than either of those of the right; also exteriorly at base each with a large tooth. From 
beneath the clypeus there projects a flat, palmate (9-digitate) brownish plate, above and 
between the mandibles; clypeus convex along its distal margin, the latter with two teeth on 
each side of its end, the first very obtuse, the second more toothlike but not large. Ocelli 
nearly in a straight line across the short vertex, the cephalic one within and at the apex of 
the short scrobicular cavity. Parapsidal furrows complete, with deep punctures. Scutellum 
normal, terminating in a short plate whose distal margin is entire though convex. Thorax 
elevated convexly in places but the convexities obtuse. A rather large toothlike plate from 
the lateral aspect of the thorax some distance ventrad of the axilla. Thorax with large 
irregular reticulations or narrow carinate lines, but not punctate except the large punctures 
in sutures. Abdomen with a distinct petiole (which is moderate in length), depressed, diamond- 
shaped from dorsal aspect, opaque. Petiole somewhat over twice longer than wide. Proximal 
tarsal joints of all the legs long and slender but the first tarsal joints are not half the 
length of the tarsi. Venation obscure, the stigmal and postmarginal veins short, much 
shorter than the marginal, the stigmal the longer of the two, curved or bent like a boomerang. 
Wings hyaline, all ciliation nearly absent; a trace of marginal cilia disto-caudad. From 
lateral aspect, scutellum appearing as if terminating in a short acute tooth. The axille meet 
mesad. 
1. EPIMETAGEA PURPUREA Girault. Female. Genotype. 
Length, 3.5 mm. 
Metallic purple, the abdomen with green reflections; knees, tibiw, tarsi (except distal 
dark part of distal joint) and the antennae, brown, the latter suffused with purplish distad. 
Venation nearly invisible but the stigmal vein brownish. Head impunctate but with very
