ARDALOIDES new genus. 
In this genus the axillae are not advanced. 
Type: The following species. 
1. ARDALOIDES SIMITHORAX new species. Genotype. 
Female: — Length, 1.80 mm. 
Lark metallic green, the abdomen black, whitish at distal third of the second segment. 
Wings with a substigmal blotch. Caudal coxfo concolorous, femora and legs brownish yellow, 
the hind femora subfuscous, the tibise lighter. Midventer of abdomen yellowish white. Thorax 
polygonally reticulated, the propodeum glabrous, with a distinct, long median carina and a 
lateral sulcus mesad of the small oval spiracle, the propodeum at apex ending in a nose; 
abdomen shining, with a long petiole, the second segment also long, obconical, depressed, 
■occupying over a third of the surface, the third less than half its length. Scutellum with 
marginal grooves which join around the apex. Parapsidal furrows short, distinct. Pronotum 
transverse quadrate. Antenna? 9-jointed wuth two ring-joints, the club solid, four funicle 
joints. Pedicel fuscous, short, funicle 1 longer than it and longest of the funicle, the next 
three joints globular. Club slightly nippled at tip, longer than any of the fiiniele joints. 
Mandibles 7-dentate. Hind tibial spurs normal. Postraarginal and stigmal veins long, the 
former the longer, the marginal somewhat shorter than the submarginal but over twice the 
length of the stigmal. 
The genus is characterised by the 9-jointed antennas with two ring-joints and the solid 
•cluh, also the long petiole. 
Male : — Hot known. 
Described from one female captured by sweeping in jungle, September 12, 1913 
(A. P. Dodd). 
Rahitat : Kuranda, Queensland. 
Type: Ko. RyB700, Queensland Museum, Brisbane, the specimen on a tag; head and 
nind legs on a slide. 
2. ARDALOIDES 10-DENTATUS new species, 
..—Differing from the typical form in having 10-dentate mandibles, the blotch 
on the fore wing subobsolete, the caudal coxm brown, the scutellum bears a short median 
sulcus at a little over proximal fourth (in the typical form in center of scutellum a round 
fovea or puncture, it is a little distad of center and may be accidental). In both species, the 
lateral half of each side of propodeum is scaly, the rest glabrous. In this species lateral 
carina? are certainly absent and true grooves but there is a groove-like depression. In the 
genotype T could not with certainty make out whether or not it was a true groove but 
apparently not. In both species the parapsidal furrows curve off some distance before 
pronotum. 
In the genotype the mandibles are pale, dark brown at tip; in this species the mandibles 
:are all dark broAvii. The scape is pale lemon yellow in both. 
Described from one species caught in forest, June 30, 1914. 
Hahitat: Gordonvale, Queensland. 
Type: Ho. }ly^701, Queensland Museum, Brisbane, the specimen on a tag.
