5. APHELINUS PERISSOPTROIDES new species. 



Female: — Length, O.so nun. Conijiareil with t\'pes of riisk-ini, miUoiii and grotiusi. 



In my table of Australian speeies, disregarding the wings, runs to grotiusi from which 

 it differs in being flattened and robust, the first cUib joint widens distad and is somewhat wider 

 than long while tlie 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. Prom rusTciiii in the distal ciliation of 

 the fore wing and general coloration. From miltoiii 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 antenna'. The ciliated areas on the fore wing are faintly 

 dusky; the bare or half-bare spots are as follows: Apical margm narrowly; a rounded area 

 just distad of venation; one in centre of blade opposite stigmal vein and one at caudal margin 

 ()p])osite 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. Scutum with a median groove. 



Prom one female cai:)tured in forest, April 17, 1914 (A. P. Dodd). 



TJahitat: Cloncurry, Queensland. 



Type: No. Hy293(), 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 

 ine.rpticahiJis. The genus Perissopterus should be carefully seutiniied 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 

 Peris.W[)terus. 



6. APHELINUS MILTONI new speeies. 

 Female: — Length, 0.07 mm. 



In my table to the Australian species running to grotiu.'ii Girault from which it differs 

 as follows: The general coloration is deeper, being golden or orange yellow; the abdomen is 

 somewhat more slender, the ovijiositor somewhat extruded as in mistraliensis; the fore wings 

 somewhat broader and Iiear 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 

 ]>roximad of it there are about six lines of discal cilia (only three in grotiusi). Mandibles. 

 H-dentate in both speeies. 



Prom one female taken in forest, January -t. 1912. 



TJahitat: Capeville (Pentland), Queensland. 



Type: No. Hy 20-31, QueenshiTid Museum, Brisbane, the specimen on a slide. 



Dedicated to John Milton. 



7. APHELINUS RUSKINI new species. 



Female: — Length, 1.15 mm. Kobnst. 



In my table of species runs to grotiusi from which it may be distinguished by having 

 both funicle joints subannular as in fu.^eipeiinis, in having the first club joint 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. Pore wings with about thirty lines of very fine 

 discal cilia where widest. Form as in fuseipennis. Dift'ers from milloui in being much more- 

 robust, duller and darker in color, in having the oblique hairless line very distinct, the cilia 

 proximad of it distinctly much coarser than those of the main ciliation. Also the first club-
