AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, VII—GIRAULT. 85 
otherwise hyaline, the venation black, the blade large, the postmarginal vein a fourth shorter 
than the stigmal the latter somewhat longer than the marginal. Third tooth of mandible 
shorter than the outer two which are equal and not long. Marginal vein a little longer than 
wide; from the stigmal an oblique hairless line which is incomplete and bounded proximad 
by five short lines of cilia. Knees and tarsi yellowish brown. Axille meeting inwardly, with 
a carina between them. Thorax densely scaly. Tegule large, reddish brown. Antenne black, 
12-jointed, joints 1 and 2 of funicle subequal, each about twice longer than wide, longer than 
the pedicel, the distal or sixth funi¢le joint a little wider than long; one very short ring-joint. 
Pronotum transverse. Scutum downy from numerous obscure setigerous punctures. Frons 
moderate. Cheeks a little over half the length of the eyes. Abdomen about as long as the rest 
ot body, conic-ovate. 
From one female taken by sweeping miscellaneous vegetation, left bank of Pioneer 
River, October 19, 1911. 
Habitat: Mackay, Queensland. 
Type: No. Hy 2986, Queensland Museum, Brisbane, the specimen on a tag; head, a fore 
wing and a hind leg on a slide. 
The club is not half the length of the funicle. Scape rather stout. Hind tibial spurs 
double. Mandibles broad. 
6. CERCHYSIUS OVIDUCTUS new species. 
Female :—Length, 0.75 mm., excluding the ovipositor which is extruded for two thirds 
the length of the abdomen. 
Metallic purple, the wings hyaline. Knees, tips of tibiz, tarsi and distal third of 
middle tibizw yellowish. Scutum and scutellum densely, finely polygonally scaly and with 
scattered, obscure, small setigerous punctures. Avxille distinctly separated for some distance. 
Seutellum metallic green at apex, a little shorter than the scutum. Valves of ovipositor black. 
Marginal vein a little longer than wide, the stigmal twice longer than it, the postmarginal 
subequal to the stigmal. Oblique hairless line present, with three or four scattered, short lines 
of cilia proximad of it, these cilia distinctly coarser than the very fine ciliation of the main 
part of the blade. Marginal cilia of fore wing very short. Abdomen flat, triangular, not 
as long as the thorax. Two outer teeth of mandibles a little longer than the inner, all acute, 
not long. Cheeks subequal in length to the eyes. the frons moderate. Head (cephalic aspect) 
rounded, the frons (lateral aspect) not prominent. Antenne inserted at the clypeus, quite as 
figured for Chalcerinys Perkins but the club is somewhat over half the length of the funicle, 
the first joint of the latter quadrate, the second a little longer than wide, the next four subequal 
in length but each very slightly broader in succession and somewhat longer than wide. Pedicel 
a little longer than funicles 1 and 2 combined. 
Male:—The same but the antenne filiform, 9-jointed, the club solid and distinetly 
longer than any of the preceding joints except the scape; pedicel short, barely longer than 
wide; funicle joints all distinctly longer than wide, 2 and 3 longest, each nearly twice longer 
than wide. Flagellum clothed with moderately long, soft hairs. 
Described from a pair captured by sweeping in the forest, December 24, 1911. 
Habitat: Double Island (Cairns), Queensland. 
Types: No. Hy 2987, Queensland Museum, Brisbane, the pair on a tag, the heads on a 
slide. 
In hispidiscutum and australis, the axille are rather broadly joined and with a carina 
between them. ‘The species australis differs from hispidiscutum mainly in having a fuscous 
band on the fore wing, that wing in the latter species hyaline; but also the marginal vein is a 
little longer in australis. The hairless line in both species is guarded proximad by short lines 
ot discal cilia, five in australis, three in hispidiscutum and the line is longer in the former.
