142 MEMOIRS OF THE QUEENSLAND MUSEUM. AUSTRALIAN HYMENOPTERA CHALCIDOIDEA— I. SECOND SUPPLEMENT. 1 By A. A. Girault. Magnification as in previous descriptions. Family TRICHOGRAMMATID^E. CH^TOSTEICHINI. Genus NEOBRACHISTA Girault. There are two funiele joints, the first transverse but wider than the ring-joints. The scape of the male is dilated veutrad, sometimes enormously. 1. NEOBRACHISTA TRIFASCIATA new species of A. P. Dodd and A. A. Girault. Female: — Length, 1.10 mm. Like novifasdata Girault but besides the three black stripes across the abdomen, there is a spot on each side of meson just caudad of the first stripe and a smaller spot on each side of meson farther caudad and more laterad ; the second and third cross-stripes are very broad, tne second not interrupted at the meson; the scutum is without the median sulcus which is present on the seutellum only; the scape is distinctly more compressed. Compared with the type of novifasdata. Male: — not known. Described from one female captured by sweeping in the jungle, January 15, 1914 (A. P. Dodd). Habitat: Gordonvale (Cairns), Queensland. Type: No. Hy ::i:i. Queensland Museum. Brisbane, the above specimen on a slide. 2. NEOBRACHISTA FASCIATA NIGRIVENTRIS Girault. The male of this variety is probably that originally described with fasciata, the abdomen black. The scape is distinctly dilated ventrad. uniformly for its entire length. The male has been re-examined. 3. NEOBRACHISTA FASCIATA Girault. The male of this species is probably represented by a specimen caught April 4, 1914 at Gordonvale, Queensland, by sweeping grass in forest. It agrees in coloration as far as I could see and in structure except that the scape is enormously dilated ventrad, very much more so than in the male mentioned above, the rectangular, flat scape only somewhat longer than wide. Seutellum with a median groove, the scutum simple. 4. NEOBRACHISTA INCOMPERTA new species. Neobrachista fasciata Girault, partim. Female: — Colored like novifasdata, the abdomen with three distinct black cross-stripes, one proximad, two distad but the second stripe is complete, not distinctly interrupted at the 1 See Memoirs Queensland Museum, II, pp. 101 to 106.
