meson. Also the marginal vein is not distinctly longer than wide, only slightly so.. Thorax 

 not seen nor hind wings. 



Habitat: Cooktown, Queensland. Jungle. 



Type: No. HySdSO, Queensland Museum. Brisbane, one female on a slide in fragments. 



5. NEOBRACHISTA NOVIFASCIATA new species. 

 Antea„ first supplement, p. 101. Length. 1 mm. Second stripe of abdomen a little 

 distad of middle, the first a little out from base. Funicle 1 not quite half the length of 2 

 (in the genotype only a fourth the length). June. Type on a slide. 



Genus NEOBKACHISTELLA Girault. 



1. NEOBRACHISTELLA MAXIMA Girault. 

 One' female, sweeping grass in forest, Gordonvale (Cairns), Queensland, April 10, 1914. 

 Wholly black, the vertex orange yellow, the thorax scaly reticulate, the so-called third ring- 

 joint is twice the size of the others (as regards width) nearly' but somewhat longer. Scape 

 short. Mandibles tridentate. The median groove of thorax is confirmed. 



GENUS CENTROBIELLA Girault. 

 1. CENTROBIELLA MAGNA Girault. 



One male, forest, Gordonvale, Queensland, April 12, 1914. The antenna? and legs are 

 dusky black; the curved line of cilia back from the stigmal vein includes about six setae. Fore 

 wings with about seventeen lines of regular discal cilia, the caudal wings with a pair of 

 conspicuous lines cephalad and a very faint line caudad. 



Also one female, the same place, May 4, 1914. by sweeping in the forest. It agrees with 

 the male. The ovipositor is extruded for half the length of the abdomen. Caudal wings with 

 three lines of discal cilia, the third faint. Thorax densely sealy-sKagreened. Pedicel and club 

 dusky black. 



In this genus, apparently, the funicle is 2-jointed as in Neobrachistella, that is. the first 

 joint very short and more or less hidden. 



Genus OLIGOSITA Haliday. 



1. OLIGOSITA SCURRA new species. 



Female: — Length, 0.70 mm. 



Differs from americana in having the funicle joint distinctly longer than wide, the body 

 golden yellow, immaculate but the distal two club joints black; the discal cilia visible (low- 

 power) only near apex. Funicle joint distinctly longer than club 1 which is not much longer 

 than wide, the middle club joint nearly twice its (the first's) length, longest of the flagellum, 

 the third joint a little shorter than the second. Pedicel a little shorter than the funicle. Fore 

 wings a little wider than their longest marginal cilia. Differs from sacra in having the funicle 

 longer than the proximal club joint, the proximal tarsal joints long and the club blackish ou 

 more than the distal half. 



Male: — Not known. 



Described from one female captured by sweeping in forest. September 16, 1913 (A. P. 

 Dodd). 



Habitat: Kuranda, Queensland. 



Type: No. Hy2121, Queensland Museum, Brisbane, the above on a slide. 



2. OLIGOSITA AMERICANA AUSTRALIS new variety. 

 Oligosita americana Girault, antea, I, pp. 76, 86. 

 Differs from americana in having the proximal tarsal joint longer and more slender, the
