 on a slide. 



TRYDYMIFORMIS new genus. 



A genus differing from Trydymus Eatzeburg in the structure of the elypeus and from 

 other genera of its tribe in the normal venation. 12-jointed antennaj and their insertion and 

 so on. 



1. TRYDYMIFORMIS AUSTRALIENSIS new species. Female. Genotj'pe. 



Length. 1.7.5 mm. Steel blue, luetallii-. the wings hyaline, the legs concolorous except 

 all of tibiae and the four proximal tarsal joints which are white. Betieulated 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 8-6 united, the latter transverse. Abdomen j^ilose. 

 Propodeum with a strong median carina. Mandibles small, bidentate. Antenna^ 12-jointed, 

 concolorous to black, inserted below the middle of the face, one ring-joint, the club 3-joiuted, 

 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 glalirous. 

 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. Hy3169, Queensland Museum, Brisbane, a female on a tag. the head and hind 

 legs on a slide. 



XEOSYST.\SIS new genus. 



Female: — Runs to Sy.stasis Walker, the antennse inserted ab<ive the middle of tlie 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 

 |iolygonally lined and with scattered umbiliiate jiuuctures. Mandibles with two acute teeth. 

 Antenna! 12-joiiited. 



1. NEOSYSTASIS UMBILICATITS new species. Genotj-pe. 



Femalt : — Length, 1.S.5 mm. 



Dark metallic blue, the head, scutellum and abdomen purple, the legs straw yellow (hind 

 eoxa metallic at base) ; also the scape, 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 \ery short. Hind wings knife-shaped, rather 

 narrow, the margin subparallel, the apex blunt. Funicle .5 a little longer than wide, 4 distinctly 

 longer than wide, a little longer than the pedicel, '.i and 2 each longer in succession proximad. 

 1 a fourth longer than 2. subequal to proxiuuU two club joints combined. Scape moderately 

 long, slender. Face with scattered thimble punctures, rather numerous; punctures numerous on 

 whole of mesonotum but a median path dowu scutellum, slightly broadening distad, narrow 

 proximad, free of punctures. Axillae not advanced, with only one or two punctures; punctures
