AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, IX.—GIRAULT. 205 
golden yellow. Stigmal vein only a little shorter than marginal; postmarginal slightly shorter 
than stigmal. Antenne 12-jointed, two ring-joints, three club joints, the first ring-joint minute; 
pedicel distinctly shorter than funicle 1 which is somewhat longer than wide, 2-5 subquadrate, 
wider than long; club not much wider than funicle, nearly as long as the three preceding joints 
united. Club joints of equal length. At least one mandible 4-dentate. 
Habitat: Gordonvale (Cairns), Queensland. Jungle, July 28, 1913 (A. P. Dodd). 
Type: No. Hy 3196, Queensland Museum, Brisbane, the female on a tag; head and hind 
legs on a slide. 
GENUS PARAHEYDENIA Cameron. 
Antenne slender, not thickened toward apex. Front wings with a small cloud on the 
costal nervure at the kase of its apical third; a larger cloud at and touching stigmal vein; 
marginal vein twice the length of stigmal; postmarginal thickened and projecting beyond 
the apex of the latter. Occiput transverse, temples obsolete above. Ocelli in a triangle. 
Eyes large, parallel; malar space distinct. Pronotum a litile longer than the mesonotum 
without the scutellum, the centre raised, widened towards the base; sides with a large, oval 
depression below the raised centre; it is distinctly narrower than the mesonotum, which is 
flat, narrowed in front and without furrows. Scutellum large, flat, wider than long, rounded 
at the base, the apex transverse; metanotum short, rounded, a keel running down the centre 
and one on either side of this on the apical half; sides bordered by a keel. First abdominal 
segment campanulate, longer than wide, the narrowed end at the base; second the longest, 
longer than the following united, the segments becoming gradually widened to the penultimate, 
the whole being shorter than the thorax. Fore-femora greatly swollen, straight on the lower, 
roundly broadly narrowed on the upper side; base in front slightly depressed in the middle; 
middle femora more slender than the hinder, as are the middle tibize than the posterior. 
Pedicel about twice longer than wide, funicle 1 twice the length of pedicel, 2 about one 
fourth shorter, the others shorter, 3 and 4 twice longer than wide, the others wider than long. 
Parapsidal furrows almost obsolete. 
ce... «6CNearly related to Heydenia, a genus which appears to be very little known. 
It is stated by Foerster to resemble one of the Dryinoide, which is certainly the case with the 
present genus. In Heydenia the parapsidal furrows are indicated; there are no keels on the 
metanotum nor clouds on the wings. ’’ 
1. PARAHEYDENIA LONGICOLLIS Cameron. Male. Genotype. 
Length, 4 mm. 
Upper part of head and thorax brassy golden, sutures blue; pleure similarly colored 
but more largely tinged with blue, especially below; abdomen dark purple, base blue, middle 
laterally tinged with golden brassy; legs dark red, four hinder coxe purple, tarsi testaceous, 
basal joint white; antennal scape red, pedicel brassy, other joints black; wings hyaline, 
venation black, an oval fuscous cloud at the stigma. Antennal furrows wide, converging and 
uniting above, dark green, closely reticulated-punctured, as is also the vertex; the rest of the 
head more finely punctured. Ocelli in an equilateral triangle, the hinder separated from each 
other by a slightly greater distance than they are from the eyes. Pronotum finely, closely 
transversely striated; pleure smooth. Mesonotum and scutellum closely, rather strongly, 
reticulated-punctured, the lateral divisions more finely than the central; mesopleurza more 
finely, similarly punctured, more finely so at the base, where there is a raised longish area, 
the narrowed end above; apex bordered by a smooth line. Metanotum smooth in the middle, 
a stout keel down its centre, with a less distinct one, bulging out in the middle, on either side 
of it; sides aciculated, also the metapleure, densely covered with white pubescence. Coxe and 
the dilated front femora closely, finely punctured; the former densely covered with white 
pubescence. Mandibles red, black at apex. Palpi white. 
Habitat: Wagga, New South Wales.
