AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, XII—GIRAULT. 281 
dark brownish. Thorax finely scaly reticulate. Abdomen suffused with brown, at distal two 
thirds crossed by a rather narrow orange transverse stripe which diffuses or broadens somewhat 
in the lateral aspect. Extruded valves of ovipositor black. Pedicel a little longer than wide, 
the funicle joints rather stout, all wider than long, enlarging distad, 5 largest and as long 
as the short pedicel. 
From one female captured by sweeping in forest, Mount Pyramid, 2,000 feet, June 3, 
1913 (A. P. Dodd). 
Habitat: Gordonvale (Cairns), Queensland. 
Type: No. Hy 8300, Queensland Museum, Brisbane, the specimen on a tag, the head 
and a hind leg on a slide. 
DITROPINOTELLA new genus. 
Female:—In J. ©. Crawford’s (1907) table of genera running to Ditropinotus Crawford 
but differing from that genus and nearly all the allied genera in bearing 12-jointed antennae 
with one distinct ring-joint, the club only 2-jointed. Hind femora compressed, unarmed, the 
tibial spurs normal. Occipital impression immargined. Propodeum with a pair of median 
carine close together and a line of fovew running from the spiracle and around the caudal 
margin. Postmarginal vein somewhat shorter than the marginal, much longer than the stigmal. 
Seutellum simple. Mandibles distinctly bidentate, the inner margin of the second tooth 
broadly, obliquely truncate. Abdomen sessile, greatly compressed (a mere line from above), 
from lateral aspect broadly ovate, the ovipositor exserted for not more than a fourth of its 
length; segments not visible in dorsal aspect but as seen dorso-laterad all the caudal margins 
straight. 
1. DITROPINOTELLA COMPRESSIVENTRIS new species. Genotype. 
Female :—Length, 1.65 mm. 
Bright metallic green, the wings hyaline, the legs yellow-brown but the coxee washed 
with metallic. Seape colored like the legs. First three or four funicle joints subquadrate, 
shorter than the pedicel, joints 5 to 7 wider than long. Scape blackish at distal half. Head 
and thorax densely finely scaly, the propodeum glabrous, the scutum and pronotum with many 
scattered thimble punctures. 
From eight specimens reared from galls with Rhicnopeltella nubilipennis Girault, 
which see. 
Habitat: Melbourne, Victoria. 
Types: In the National Museum, Melbourne, five females on a tag; one fore leg, 
several hind ones and heads on a slide. 
IDARNIN. 
IDARNOMORPHA new genus. 
Female :—Like Idarnes Walker but the antenne are 13-jointed with one rimg-joint, the 
club 4-jointed, the last joint minute, like a nipple yet articulated. Mandibles bidentate. 
Extruded portion of the ovipositor about three and a half times longer than the body. 
Postmarginal vein nearly a half longer than the rather long stigmal, as long as the marginal 
vein. Funicle joints barely longer than wide, shorter than the pedicel. Ring-joint large. 
Abdomen depressed, longer than the thorax. Mandibles tridentate. Coxe not especially long. 
Seutellum flat, with two grooves, one on each side. 
Male :—Antennx 3-jointed, the last two joints forming a club. Mandibles strongly 
bidentate. Tarsi 5-jointed, the three intermediate joints transversely linear. Head with an 
antennal fovea, longer than wide. Wings entirely (apparently) absent.
