1. TETRACAMPOIDES SETOSUS new species of A. P. Dodd. Genotype. 

 Female: — Length, 1.75 mm. 



Dark metallic blue, the coxas and femora concolorous, the scutellum and base of abdomen 

 brighter, the tibias and tarsi white, the antennas wholly black. Thorax with exceedingly fine 

 scaly sculpture and long whitish pubescence, the propodeum quite smooth. Abdomen with 

 second segment smooth, the rest with sculpture and pubescence like the thorax. Wings hyaline. 

 Scape moderately slender, the pedicel not long but as long as first two funicle joints combined; 

 flagellum somewhat elavate, the funicle joints fully twice as wide as long; club with a terminal 

 nipple, the club joints all much wider than long. 



Described from one female caught in jungle, February 5, 1914 (A. P. Dodd). 



Habitat: Babinda, Queensland. 



Type: No. Hy2495, Queensland Museum, Brisbane, the female on a tag; head on a slide. 



The middle lateral tooth on propodeum is really the acute caudo-lateral angle of that 

 region. — A. A. Girault. 



PLATTTETRACAMPE new genus. 



Male: — Form flattened, the vertex flat, the face much inclined ventro-caudad, the 

 antennas inserted at the mouth border, capitate, 11-jointed without ring- joints, the club 3-jointed, 

 the six funicle joints annular, the distal two stalked. Pronotum rather large, the scutum 

 wider than long, without a trace of furrows. Marginal vein longer than the submarginal but 

 not very long, the postmarginal one half the length of stigmal, the latter slender but rather 

 short. Mandibles bidentate. Scutellum simple. Tarsi 4-jointed. Abdomen rounded subquad- 

 rate, flat, with a very short petiole, all the segments short, transverse. Spiracle of propodeum 

 minute, round. Propodeum with a rather stout transverse carina at cephalic third (in reality 

 the caudal margin of the sunken postscutellum which continues laterad across the lateral part 

 of the propodeum cephalad of the spiracle), at the meson with two carinas which are curved 

 and wide apart, with a narrow, rather obscure sulcus in the place of the lateral carinas and an 

 oblique, complete carina just laterad of the spiracle. Hind femur swollen just before tip. 

 Hind tibial spur single. 



Female: — Not known. 



1. PLATYTETRACAMPE FUNICULUS new species. Genotype. 



Male: — Length, 0.90 mm. 



Black, shining; tarsi except first joint of hind tarsus and the funicle silvery white. 

 Fore wing yellowish under the marginal vein (margin to margin, the infumation suffused). 

 Pedicel over three fourths the length of the funicle, the joints of the latter rapidly widening 

 distad, 6 largest. Club a little longer than the pedicel. Scape not enlarged. Distal club joint 

 with a short nipple. Whole body scaly reticulate. 



From one male caught by sweeping in jungle, December 2, 1913 (A. P. Dodd). 



Habitat: Kuranda, Queensland. 



Type: No. Hy2496, Queensland Museum, Brisbane, the specimen on a tag; head, pair
