AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, VII—GIRAULT. 83 
3. CERCHYSIELLA UMBILICATA new species. 
Female: Length, 2 mm. 
Dark metallic green, the abdomen purple except at extreme base; legs and antenne 
reddish brown except club, coxe and proximal half of femora; pedicel a little dusky. Wings 
very slightly stained. Mandibles long, slender, with two strong, acute outer teeth and a third 
much shorter inner one. Axillew a little separated. Head and thorax densely scaly, the vertex 
with scattered umbilicate punctures and a row of same along the eyes; scutum and scutellum 
umbilicately punctate, the punctures moderately coarse, not confluent, absent along the meson 
of scutellum. Abdomen very finely scaly, as long as the rest of the body, the ovipositor a little 
extruded. Propodeum subglabrous, with three narrow carine at the meson, the three well 
separated. Hind tibial spurs double, unequal. Scape distinctly compressed, (excluding bulla) 
stouter than the funicle; pedicel not much longer than wide at apex, longer than funicle 1 
which is longest yet barely longer than wide; following joints gradually shortening and 
widening; club no more than half the length of the funicle whose distal three joints are 
subpetiolate. Thorax clothed with short black hairs. Cheeks nearly half the length of the 
eyes. Frons moderately broad. Secrobes deep, forming a semicircle. Hind wings curved. 
Marginal vein about twice longer than wide, the stigmal long, curved, a half longer than the 
marginal; postmarginal vein not half the length of the marginal. Pronotum transverse. Costal 
cell of hind wings extending to the hooklets. 
From one female taken in jungle, May 8, 1913 (A. P. Dodd). 
Habitat: Gordonvale (Cairns), Queensland. 
Type: No. Hy 2982, Queensland Museum, Brisbane, the specimen on a tag; a fore wing, 
head and hind tibia on a slide. 
GENUS CERCHYSIUS Westwood. 
1. CERCHYSIUS AUSTRALIENSIS Ashmead. Female. 
Length, 2.6 mm. 
Afneous-black, the head blue-black, the face ventrad of scrobes metallic bluish green, 
the mesopleura, scutellum and abdomen decidedly metallic greenish; antennzw black; legs except 
coxe, distal half of hind femora and proximal two thirds of hind tibize, brownish yellow. Wings 
fuscous, the proximal one third hyaline. Venation brown. Stigmal and postmarginal veins 
longer than the marginal. Ovipositor about the length of the first joint of hind tarsi, their 
valves broad. j 
Habitat: Australia.

2. CERCHYSIUS HISPIDISCUTUM new species. 
Female: Length, 2 mm., excluding ovipositor. 
Similar to Rhopalencyrtoidea claripennis but at once distinguished specifically by the 
distinet whitish pubescence on the scutum (present in that species but not conspicuous), the 
whitish knees and tarsi, the wholly concolorous middle tibiz, the dark eneous green colour, the 
legs and abdomen (except at base) very dark purple, by the shorter marginal vein which is 
punctiform or nearly, slightly longer than wide, the somewhat shorter postmarginal (in relation 
to the stigmal), by the slender scape, the slender pedicel and the longer first two joints of the 
funicle which are longest, subequal, each a little over twice longer than wide and somewhat 
longer than the pedicel which is subequal to funicle 4. The ovipositor is extruded for a 
distinctly greater length (about two thirds the length of abdomen). Sculpture similar in both, 
or nearly but in the fore wing the discal ciliation is absent proximad until near the tip of the
