AVSTBALIAN HYMENOPTEBA CHALCIDOIDEA, IV.—GIBAVLT. 
1ST 
ZAOMMOMENTEDON new genus. 
Female : — In my table of genera runs to Plcurotropomyia Giranlt from which it differs 
in bearing a complete, distinct median sulcus on the seutellum in addition to one along distal 
two thirds of scutum. Also the eyes occupy near the whole side of the head, the antennse- 
inserted far down near tlie mouth, the scrobes 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 stignial veins unecpial, the former longer, subelongate, the 
latter a little longer than usual, the marginal vein very long. Hind tibial spur normal. 
Propodeum with distinct lateral caringo only, these joining along caudal margin, the spiracle 
minute, round. Lateral carina at base (cophalad) 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 cai'ina3 indicated at apex of propodeum by short spurs from 
the earinated caudal margin. Abdominal petiole slender, longer than the hind coxae. Second 
segment of alulomeu short, somewliat longer than the others; seutellum long. Mandibles- 
6-dentate! Axillge barely advanced. 
Male : — Not known. 
1. ZAOMMOMENTEDON MANDIBULARIS new species. Genotype. 
Female: — Length, 1 mm. 
^letallic blue-green, the wings hyaline, the legs (except hind coxse, other coxaa not 
plainly seen) and scape pure wliite. Pronotum, propodeum, extreme meso-caudal angles of 
parapside and apex of seutellum glabrous, the pronotum with a line of fovea across cephalie 
edge. Head and rest of thorax polygoually lined, the lines not raised. Hind wings with 
about seven lines of discal cilia whore broadest. Eunicle joints oval, 1 a little the longest,, 
the pedicel still smaller. Terminal seta of club short, distinct. 
From one female caught in jungle, January IS, 1914 (A. P. Dodd). 
IfaMtai: Gordonvale (Cairns), Queensland. 
Type: No. TTySiSG^ Queensland oyfuseuin, Brisbane, the specimen on a tag, the head on 
a slide. 
NEOPSEUDACPIASi 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, tlie second abdominal segment occupies fully two thirds of the 
surface. Propodeum with a pair of diverging median carinfe and true lateral carina3. Antennae 
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 gi'oeu, the abdomen darker, the propodeum coppery, the coxas concolorous; 
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 scutelbun smooth. Propodeum smooth. Petiole short and 
stout, the abdomen stout, cojiic-ovate. Pedicel shorter than any of the funicle joints, which 
are much longer than wide, the finst slightly the longest, the first club joint subecptal to funicle 
.3 and longer than 2 which terminates in a short spine. Mamlibles bidentate, the teeth acute. 
From one female caught by sweeping foliage in jungle, May 19, 1913 (A. P. Dodd). 
Hahitat: Kuranda, Queensland. 
Type: No. Ily2487, Queensland Museum, Brisbane, the specimen on a tag, the head 
and a hind leg on a slide.
