AUSTRALIAN EYMENOPTEEA CHALCIDOIBEA, IV.— GIRAULT. 283- 



2. ALOPHOMORPHELLA NIVEIPES new species. 



Female: — Length, 2.5 mm. 



Dark metallic green, the legs (except caudal coxae) and the scape white. Scutellum and 

 axillae brassy. Fore wings with a long-ovate dusky spot with its axis obliqued caudo- 

 proximad from the end of the stigmal knob; but this spot does not touch the stigmal vein 

 being half the length of that vein directly caudad of its apex. Antennas black; funicle ] 

 distinctly the longest, elongate, twice the length of the pedicel, longer than the club; funicles- 

 2 and 3 subequal, 4 shorter than 3, slightly longer than wide; third club-joint nipple-like, 

 itself with a short, stout terminal nipple. Mandibles about 6-dentate. Stigmal vein a little 

 over a third the length of the marginal, shorter than the postmarginal yet slender. Grooves 

 of scutellum joined around apical margin. Abdomen glabrous, distad finely scaly. Thorax 

 densely punctate, the axilla? and scutellum more densely scaly, the propodeum glabrous, with a 

 distinct median carina which has a narrow sulcus along each side of it; lateral carina 

 represented by a straight line of fovea? running meso-caudad from the spiracle to near apex 

 of the median carina; this lateral line of foveas does not reach the spiracle by the latter 's own 

 diameter and a little more. Spot on fore wing not twice longer than wide. 



From one female taken in jungle, May 3, 1914 (A. P. Dodd). 



Habitat: Tweed Heads (Tweed Eiver), New South Wales. 



Type: No. Hy 2691, Queensland Museum, Brisbane, the specimen on a tag; head and 

 caudal tibia on a slide. 



PAEENTEDON new genus.

1. PARENTEDON AUSTRALIS new species. 

 Length, 2 mm. The types were taken in forest, December 27, 1912 and January 8, 1913. 



2. PARENTEDON SOBRINUS new species of Girault and A. P. Dodd. 



Female: — Length, 1.95 mm. 



Similar to the genotype but the abdomen is more uniform in color (not submetallie 

 distad) and darker, the margins still obscurely darker. The following structural differences: 

 The grooves on the scutellum are separated around distal margin by only slightly more than 

 their own width (distinctly more separated in australis) ; on the propodeum there are a 

 number of weak oblique carina? from the side of the distinct median carina and also from 

 the cephalic margin of propodeum mesad of the spiracle, the longitudinal space between the 

 two groups of carinas, smooth, the lateral of the two separated from the small round spiracle 

 by a broad complete sulcus; caudal margin of propodeum cariuated, turning up toward the 

 spiracle and thus forming the more or less distinct lateral carinas as in australis; the spiracle 

 is somewhat larger in this species; sculpture of mesothorax alike in both species; mandibles 

 with only eleven teeth. Antennas dark, scape whitish, the pedicel so beneath ; funicle 4 quadrate. 



Described from one female caught by sweeping in forest, June 18, 1912 (A. A. Girault). 



Habitat: Northern Queensland (Gordonvale near Cairns). 



Type : No. Hy 26B2, Queensland Museum, Brisbane, the above specimen on a tag. 



Both australis and the above species have a hoodlike neck at apex of propodeum. 



3. PARENTEDON SIMILIS new species of Girault and A. P. Dodd. 



Female .'—Length, 1.50 mm. 



Similar to the preceding species (sobrinus) but slenderer, the abdomen slenderer and 

 brownish interiorly (along mesal portion) only, the femora and tibia? nearly white, the abdomen 

 narrower and with a short, distinct petiole and the second segment occupies only a third of 

 the surface (not a half or nearly). Mandibles 14-dentate. Segments 3 and 4 of abdomen,
