Female :—Length, 2 mm. 
Like insularis but the tibize concolorous also except the cephalic tibia which are washed 
with metallic green dorsad; antennzw wholly black wneous, the funicle joints all a little longer 
than wide, somewhat shorter than the pedicel and subequal to each other. Vertex and upper 
face with numerous thimble punctures. Propodeum not seen. Second and third teeth of 
mandibles not very well differentiated, short, obtuse, the division between them rather shallow. 
Postmarginal vein distinctly longer than the stigmal. Tips of tibiew whitish. 
Described from one female taken from a window, March 18, 1914. 
Habitat: Gordonvale (Cairns), Queeensland. 
Type: No. Hy 3168, Queensland Museum, Brisbane, the fore wings, head and hind tibia 
- on a slide. 
TRYDYMIFORMIS new genus. 
A genus differing from Trydymus Ratzeburg in the structure of the clypeus and from 
other genera of its tribe in the normal venation, 12-jointed antenna and their insertion and 
so on. 
1. TRYDYMIFORMIS AUSTRALIENSIS new species. Female. Genotype. 
Length, 1.75 mm. Steel blue, metallic, the wings hyaline, the legs concolorous except 
all of tibiz and the four proximal tarsal joints which are white. Reticulated and with scattered 
minute setigerous punctures, the abdomen densely reticulated, except the second segment which 
is glabrous and occupies about half of the surface. Abdomen depressed, ovate, as long as the 
thorax, segment 7 longer than segments 3-6 united, the latter transverse. Abdomen pilose. 
Propodeum with a strong median carina. Mandibles small, bidentate. Antennewe 12-jointed, 
concolorous to black, inserted below the middle of the face, one ring-joint, the club 3-jointed, 
the distal one terminating in a distinct spinelike seta. Funicle joints transverse, all shorter 
than the pedicel, the first longest and narrowest, the last three subequal. Propodeum glabrous. 
Marginal vein subequal to the submarginal, the stigmal shorter than the postmarginal. Clypeus 
not produced at meson, there gently concaved. 
Habitat: Gordonvale (Cairns), Queensland. Jungle, June 14, 1913. 
Type: No. Hy 3169, Queensland Museum, Brisbane, a female on a tag, the head and hind 
legs on a slide. 
NEOSYSTASIS new genus. 
Female :—Runs to Systasis Walker, the antenneze inserted above the middle of the face 
but the first funicle joint is elongate, the postmarginal vein elongate, over twice the length of 
the stigmal, the abdomen long and conical, longer than the rest of the body, the thorax is finely 
polygonally lined and with scattered umbilicate punctures. Mandibles with two acute teeth. 
Antenne 12-jointed. 
1. NEOSYSTASIS UMBILICATUS new species. Genotype. 
Female :—Length, 1.85 mm. 
Dark metallic blue, the head, seutellum and abdomen purple, the legs straw yellow (hind 
coxa metallic at base); also the seape, the club suffused with whitish. Fore wings distinctly 
infuscated, the infuscation taking the shape of an obscure midlongitudinal line which diffuses 
over the blade from each side. Marginal fringes very short. Hind wings knife-shaped, rather 
narrow, the margin subparallel, the apex blunt. Funicle 5 a little longer than wide, 4 distinetly 
longer than wide, a little longer than the pedicel, 3 and 2 each longer in succession proximad, 
1 a fourth longer than 2, subequal to proximal two elub joints combined. Scape moderately 
long, slender. Face with scattered thimble punctures, rather numerous; punctures numerous on 
whole of mesonotum but a median path down scutellum, slightly broadening distad, narrow 
proximad, free of punctures. Axilla not advanced, with only one or two punctures; punctures
