5. APHELINUS PERISSOPTROIDES new species. 
Female :—Length, 0.80 mm. Compared with types of ruskini, miltoni and grotwst. 
In my table of Australian species, disregarding the wings, runs to grotiusi from which 
it differs in being flattened and robust, the first club joint widens distad and is somewhat wider 
than long while the discal ciliation of the fore wings is broken into naked areas forming a 
colorless pattern somewhat as in Perissopterus except that the ciliated spaces are not infuscated 
deeply and the hairless ones less numerous than usual. From ruskini in the distal ciliation of 
the fore wing and general coloration. From miltoni much as from grotiusi. From fuscipennis 
in bearing but seven lines of cilia proximad of the hairless line, in having the pattern on the 
fore wing and somewhat different antennw. The ciliated areas on the fore wing are faintly 
dusky; the bare or half-bare spots are as follows: Apical margin narrowly; a rounded area 
just distad of venation; one in centre of blade opposite stigmal vein and one at caudal margin 
opposite the one distad of venation. When viewed with a lens, there appear to be four rounded 
faintly dusky spots arranged in a square in the centre of the wing. Mandibles bidentate. 
Legs white, immaculate. Postscutellum transverse. Seutum with a median groove. 
From one female captured in forest, April 17, 1914 (A. P. Dodd). 
Habitat: Cloncurry, Queensland. 
Type: No. Hy 2920, Queensland Museum, Brisbane, the female on a slide. 
This species has all the characters of Perissopterus except the small triangular post- 
scutellum; the mesonotal sclerites seem quite normal as do also those of my Perissopterus 
inexplicabilis. The genus Perissopterus should be carefully scutinized because its general 
resemblance to Aphelinus is most striking and we have just seen a species of the latter which has 
the fore wings which approach the peculiar type of wing pattern common to species of 
Perissopterus. 
6. APHELINUS MILTONI new species. 
Female :—Length, 0.67 mm. 
In my table to the Australian species running to grotiusi Girault from which it differs: 
as follows: The general coloration is deeper, being golden or orange yellow; the abdomen is 
somewhat more slender, the ovipositor somewhat extruded as in australiensis; the fore wings 
somewhat broader and bear shorter marginal fringes; club 1 is longer than wide (subquadrate 
in grotiusi); and in the fore wing, the oblique hairless line is barely differentiated and 
proximad of it there are about six lines of discal cilia (only three in grotiust). Mandibles. 
3-dentate in both species. 
From one female taken in forest, January 4, 1912. 
Habitat: Capeville (Pentland), Queensland. 
Type: No. Hy 2921, Queensland Museum, Brisbane, the specimen on a slide. 
Dedicated to John Milton. 
7. APHELINUS RUSKINI new species. 
Female :—Length, 1.15 mm. Robust. 
In my table of species runs to grotiusi from which it may be distinguished by having 
both funicle joints subannular as in fuscipennis, in having the first club joimt cup-shaped, 
somewhat wider than long, in bearing about seven lines of discal cilia proximad of the hairless. 
line, in being more robust and in bearing a distinct median groove on the thorax. General 
color dull honey yellow tinged with reddish. Fore wings with about thirty lines of very fine 
discal cilia where widest. Form as in fuscipennis. Differs from miltoni in being much more 
robust, duller and darker in color, in having the oblique hairless line very distinet, the cilia 
proximad of it distinctly much coarser than those of the main ciliation. Also the first club-
