1. NEOCAUDONIA SPINOSICLAVA new species of Girault and A. P. Dodd. 
Female. Genotype. 
Length, 3.50 mm. 
Very dark metallic green, the coxe, tibie and femora concolorous, the abdomen somewhat 
brighter, brilliant at base, the tarsi pale straw yellow, the antenne wholly black. Wings hyaline. 
Thorax (including propodeum) densely punctate. Abdomen finely scaly, the second segment 
smooth. Ring-joints wider than long; first funicle joint distinctly the longest, twice as long 
as the pedicel, which is as long as 6, the first club joint shorter than the second. Club no 
longer than funicle 1. Each end of tibia yellowish white. Clypeus longitudinally striate. 
One female, Halifax, March 29, 1914 (A. P. Dodd). 
Habitat: Babinda, Queensland. Jungle, February 11, 1914 (A.P.D.). 
Type: No. Hy 8203, Queensland Museum, Brisbane, the female on a tag; head and legs

2. NEOCAUDONIA AUREICORNIS new species of A. P. Dodd and A. A. Girault. 
Female.

the tibiz and tarsi yellow, the antennew yellow brown; funicle 1 barely longer than pedicel, no

Type: No. Hy 3204, Queensland Museum, Brisbane, the female on a tag, the head on a 
slide. 
A second female at Gordonvale, Queensland, April 27, 1913 (A. A. Girault). 
‘‘This genus appears to me to be the same as Amicromelus Girault of the Misco- 
gasteride’’ (A. A. Girault). 
TRIGONODEROPSIS new genus. 
In Ashmead’s (1904) table of genera running to Trigonoderus Westwood but the 
abdomen is totally different, being short sessile and ovate, no longer than the rest of the body 
and the scutellum has a transverse line of fine punctures across it. Propodeum with a distinet 
median carina but no others, polished. Marginal vein five or more times longer than the 
stigmal, the latter short, less than half the length of the postmarginal, the wings hyaline. 
Second abdominal segment longest, occupying about between a third and a half of the surface. 
Antenne 13-jointed, with two ring-joints, the club 3-joimted. Pronotum wider than long, 
transverse but with a median neck. Both mandibles 4-dentate, the maxillary palpi 4-, the 
labial, 3-jointed. Club short, ovate, without a nipple, the pedicel short, the funicle joints 
except the short first, wider than long. Parapsidal furrows very deep. Cephalic femur
