AUSTRALIAN HYMENOPTEEA CHALCIDOWEA, IV.—GIBAULT. 287 



AEDALOIDES new genus. 

 In this genus the axillas are not advanced. 

 Type: The following species. 



1. ARDALOIDES SIMITHORAX new species. Genotype. 



Female: — Length, 1.80 mm. 



Dark metallic green, the abdomen black, whitish at distal third of the second segment. 

 TVings with a substigmal blotch. Caudal coxa? concolorous, femora and legs brownish yellow, 

 fhe hind femora subfuscous, the tibiae 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. Antennas 9-jointed with 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 funicle joints. 

 Mandibles 7-dentate. Hind tibial spurs normal. Postmarginal 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 antenna? with two ring-joints and the solid 

 •club, also the long petiole. 



Male: — Not known. 



Described from one female captured by sweeping in jungle, September 12, 1913 

 (A. P. Dodd). 



Habitat: Kuranda, Queensland. 



Type : No. Hy 2100, Queensland Museum, Brisbane, the specimen on a tag ; head and 

 nind legs on a slide. 



2. ARDALOIDES 10-DENTATUS new species. 



Female: — Differing from the typical form in having 10-dentate mandibles, the blotch 

 on the fore wing subobsolete, the caudal coxae 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 

 carinae are certainly absent and true grooves but there is a groove-like depression. In the 

 genotype I 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 mandible? 

 are all dark brown. The scape is pale lemon yellow in both. 



Described from one species caught in forest, June 30, 1914. 



Habitat: Gordonvale, Queensland. 



Type: No. Hy2701, Queensland Museum, Brisbane, the specimen on a tag.
