AUSTRALIAN HTMENOPTEBA CHALCIBOIDEA, IV.—GIBAULT. 197 



•compressed. Head and thorax very densely, finely polygonally scaly or shagreened, the thorax 

 with some scattered thimble punctures. A line of foveae across cephalic edge of propodeurn, 

 the latter shining but with faint scale-like sculpture which is not quite as distinct as that 

 of the abdomen. 



Habitat : Melbourne, Victoria. Galls on Eucalyptus. Four males, six females, September 

 ll. 4 



Type: In the National Museum, Melbourne, two pairs on a card, a slide with a male 

 antenna and female head, wings and hind legs. 



2. OMPHALOMORPHELLA BICOLOR new species. 



Female: — Length, 0.80 mm. 



Antennae inserted a little below the middle of the face, 11 -jointed with two ring-joints, 

 the club 3-jointed and with a distinct terminal spine, the flagellum rather strongly clavate, 

 the second ring- joint very large, nearly as large as funicle 1 yet distinctly shorter; first ring- 

 joint very short. Mandibles with two equal acute teeth, small. Scutellum simple. Propodeum 

 with a median carina but no others, short at meson, finely scaly. Thorax polygonally reticulated, 

 the lines indented. Marginal vein longer than in the genotype, a little longer than the 

 submargmal (not distinctly shorter as in auripes) , distinctly longer than the elongate post- 

 marginal which is twice the length of the stigmal. Hind tibial spur single, small. 



Black, the wings subhyaline, the abdomen yellowish brown, pale yellow across base and 

 with about five obscure dusky cross-stripes. Legs concolorous with abdomen, the coxae dark, 

 subeoncolorous. Tibiae and tarsi pallid, also the scape; rest of antenna black. Funicles 1 and 

 2 wider than long, small, 2 a little longer; 3 and 4 each abruptly enlarging, 4 large and 

 globular, yet a little shorter than the pedicel; 3 distinctly wider than long. Funicle 3 twice 

 the size of 1. 



From one female captured in jungle, November 15, 1913 (A. P. Dodd). 



Habitat: Harvey's Creek (Cairns), Queensland. 



Type: Xo. Hy 2508, Queensland Museum, Brisbane, the specimen on a tag; head and

Genus OMPHALOMOMYIA Girault. 



The genus bears four ring- joints. 



1. OMPHALOMOMYIA LIVIDICAPUT Girault. 



A female, forest, Gordonvale, Queensland, May 8, 1914. Second ring-joint of the four 

 very short, the others rather large. Funicle 3 at least half the length of the long pedicel, 

 1 somewhat longer than wide. In this second female the par apsides were not washed with 

 purple. Propodeum scaly, with a carina just laterad of the spiracle. Wings subhyaline. Type 

 re-examined but not the type antennas. 



Genus CHEYSOCHAEIS Foerster. 

 1. CHRYSOCHARIS DUMASI new species. 



Female: — Length, about 1.30 mm. 



Very similar to Achrysocharoides sarcophagus Girault except that the scutellum is 

 simple and the hind femur and proximal half of hind tibia are concolorous with the body, 

 the fore femur and tibia slightly washed with dusky. The scape is wholly concolorous and 

 as deeply colored as the rest of the antenna. Hind wing short, acutely pointed. Marginal 

 fringes of the fore wing short. Funicle 3 barely longer than the pedicel, a little the shortest, 

 1 broad, a little the longest of the funicle; club 2-jointed. Hind wing where widest (apex of 



* Labels indefinite. The numbers were 64 and 7. The dates were 9.11 and 4.11 which may mean 

 November 4 and 9, September 11 and April 11 or September and April, 1911.
