Tribe SPHEGIGASTEEINI. 



The Australian genera of this tribe may need thorough revision. The genera are 

 difficult to define. 



Genus SYNTOMOPUS Walker. 



1. SYNTOMOPUS AUSTRALIENSIS Girault. 



The propodeum bears three distinct carinae, a median and two lateral. The type is 

 probably a female, stated to be a male in the original description. It has been re-examined. 

 The type measures 1.75 mm., is on a slide and was captured at Kuranda, Q., December 18, 

 1912. 



Genus MEEISMUS Walker. 



1. MERISMUS SQUAMOSUS new species. 



Female: Length, 1.20 mm. 



Dark purplish, the wings hyaline, the stigmal vein about half the length of the marginal, 

 the postmarginal distinctly longer than the stigmal. Legs yellowish brown, also the scape. 

 Thorax reticulate scaly, the scutellum distad of the transverse line glabrous. Propodeum long, 

 with a short neck, strongly tricarinate. Second abdominal segment occupying somewhat over 

 half of the surface, deeply semicircularly emarginate, the third segment not half its length. 

 Mandibles 4-dentate. Petiole a little longer than the hind coxae. Club long, with an apparent 

 fourth joint near tip, the distal funicle joints quadrate, funicle 1 subequal to the pedicel, 

 somewhat longer than wide. Antennae 13-jointed with two ring-joints. Pronotum transverse, 

 its cephalic margin subacute. 



Male: — Not known. 



Described from one female captured by sweeping in forest, April 7, 1913. 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. Hy 2790, Queensland Museum, Brisbane, the specimen on a tag, the head 

 and hind legs on a slide. 



2. MERISMUS SCUTELLARIS new species of A. P. Dodd and A. A. Girault. 



Female: — Length, 1.75 mm. 



Dark metallic green, the legs (including the coxae) and antennal scape golden yellow, 

 rest of antennae black. Scutum and propodeum densely reticulated, the parapsides, axillae and 

 scutellum almost smooth, and shining. Scutellum with a very distinct cross-suture and also 

 with a deep oval fovea or depression in its centre. Propodeum long, strongly tricarinate. 

 Abdomen short, convex above, straight beneath, the petiole as long as the hind coxae, the second 

 segment occupying over half of the surface, its caudal margin straight. Wings hyaline; 

 marginal vein scarcely longer than the postmarginal and twice as long as the stigmal. Mandibles 

 4-dentate. Pedicel somewhat longer than any of funicle joints which are subquadrate, a 

 little longer than wide, club joints longer than wide. 



Described from one female caught sweeping foliage and grass along the Mulgrave Eiver, 

 mostly jungle, March 30, 1913 (A.A.G.). 



Habitat: Mulgrave Eiver (Gordonvale), Queensland. 



Type : No. Hy 2791, Queensland Museum, Brisbane, the specimen on a tag, the head
