AUSTRALIAN HYMEN OPTERA CHALCIDOIDEA, IV.—GIRAULT. 187 



ZAOMMOMENTEDON new genus. 



Female: — In my table of genera runs to Pleurotropomyia Girault from which it differs 

 in bearing a complete, distinct median sulcus on the scutellum in addition to one along distal 

 two thirds of scutum. Also the eyes occupy near the whole side of the head, the antennae 

 inserted far down near the mouth, the serobes short, forming a triangle but continued to the 

 cephalic ocellus in the form of a long sulcus. Eyes hairy, rather coarse, not reaching to base 

 of mandible. Postmarginal and stigmal veins unequal, the former longer, subelongate, the 

 latter a little longer than usual, the marginal vein very long. Hind tibial spur normal. 

 Propodeum with distinct lateral carina? only, these joining along caudal margin, the spiracle 

 minute, round. Lateral carina at base (cephalad) forking, a short branch running latero- 

 caudad, mesad of the spiracle and a complete, narrow sulcus just laterad of spiracle. A pair 

 of rather widely separated median carina; indicated at apex of propodeum by short spurs from 

 the carinated caudal margin. Abdominal petiole slender, longer than the hind coxa?. Second 

 segment of abdomen short, somewhat longer than the others; scutellum long. Mandibles' 

 6-dentate! Axilla? barely advanced. 



Hale: — Not known. 



1. ZAOMMOMENTEDON MANDIBULARS new species. Genotype. 



Female: — Length, 1 mm. 



Metallic blue-green, the wings hyaline, the legs (except hind coxa?, other coxaa not 

 plainly seen) and scape pure white. Pronotum, propodeum, extreme meso-caudal angles of 

 parapside and apex of scutellum glabrous, the pronotum with a line of fovea across cephalic 

 edge. Head and rest of thorax polygonally lined, the lines not raised. Hind wings with 

 about seven lines of discal cilia where broadest. Funicle joints oval, 1 a little the longest, 

 the pedicel still smaller. Terminal seta of club short, distinct. 



From one female caught in jungle, January 18, 1914 (A. P. Dodd). 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. Hy 2486, Queensland Museum, Brisbane, the specimen on a tag, the head on 

 a slide. 



NEOPSEUDACRIAS new genus of A. P. Dodd. 



Female: — Agreeing with Pseudacrias Girault but there are only two ring-joints, the 

 hind tibial spur is not stout, the second abdominal segment occupies fully two thirds of the 

 surface. Propodeum with a pair of diverging median carina? and true lateral carina?. Antenna? 

 9- jointed, the funicle 3, the club 2- jointed. 



Male: — Not known. 



1. NEOPSEUDACRIAS SPLENDIDUS new species of A. P. Dodd. Genotype. 



Female: — Length, 1.75 mm. 



Dark metallic green, the abdomen darker, the propodeum coppery, the coxa? concolorousj 

 rest of legs and antennal scape intense lemon yellow, rest of antenna? black. Wings hyaline,, 

 the stigmal and postmarginal veins very short. Thorax finely reticulate, the reticulation in 

 raised lines, the center and apex of scutellum smooth. Propodeum smooth. Petiole short and 

 stout, the abdomen stout, conic-ovate. Pedicel shorter than any of the funicle joints, which 

 are much longer than wide, the first slightly the longest, the first club joint subequal to funicle 

 3 and longer than 2 which terminates in a short spine. Mandibles bidentate, the teeth acute. 



From one female caught by sweeping foliage in jungle, May 19, 1913 (A. P. Dodd). 



Habitat: Kuranda, Queensland. 



Type: No. Hy 2487 , Queensland Museum, Brisbane, the specimen on a tag, the head 

 and a hind leg on a slide.
