6. ABLERUS SAINTPIERREI new species. 
Female : — Length, 0.85 mm., excluding ovipositor which is half the length of the abdomen. 
Like speciosus but more robust, the wings broader and the black stripe around hind tibia} 
is at apex; the fore wings, moreover, bear very short marginal cilia. Stripe of fore wing from 
the stigma! vein ; face blue-green at ventral half. 
From one female captured on a window, February 3, 1912. 
Habitat: Cooktown, Queensland. 
Type: No. Hy 1737 , Queensland Museum, the above specimen on a slide. 
7. ABLERUS HYALINU3 new species. 
Female: — Length, 1.15 nun., excluding ovipositor which is a fifth the length of the 
abdomen. 
Differing from the preceding species in bearing nearly hyaline wings; otherwise like 
speciosus but the legs are wholly white; ovipositor valves white at tip; mesopostscutellum 
with a silvery lustre, the parapsides white. Closely allied with speciosissi mu$ (see table). Like 
speciosisf.imus but. the thorax with a straight, narrow’ silvery white band across it between the 
scutellum and posteeutellmn. Hind coxao at proximal half couoolorous. Silvery white at tip 
of abdomen centrally and down mesopleurum from apex of the white on the parapside. Face 
with a metallic wavy stripe across it through the antennas, occiput concolorous at ventral half. 
The faint stripe across the fore wing in both species originates at about the distal third of the 
marginal vein, in hyalinus, the wing stripe is extremely faint. A second specimen was larger, 
more robust. 
From one female reared from a mass of galls on Eucalyptus, September 3, 1912. 
Habitat: Nelson (Cairns), Queensland. 
Type: No. Hy 1738, Queensland Museum, the above specimen on a slide. 
8. ABLERUS GROTIUSI new species. 
Female: — Length, 0.70 mm. 
Differing from all the Australian species in having a wing pattern like the Javanese 
pulchriceps Zehntner. From that species, however, differing in being smaller, the fore wings 
narrower, their longest marginal cilia over half the greatest wing width (in the Javanese 
species less than half) ; in this Australian species, the wing pattern is less distinct, the spot 
at the distal margin of the blade is longer and extends over more of the apical margin; of 
the two large white spots distad of the w’hite stigmal vein, the distal one is larger (hardly so 
in pulchriceps where both are large and subequal) ; the area leading proximad from the apex of 
the blade does not form a prong like fuscous marking. Moreover, in groliusi, the white second 
funicle joint is subquadrate like the third which it equals, while in pulchriceps it is twice the 
size of the black third joint and only slightly shorter than the first and fourth. 
Male : — Unknown. 
Described from one female captured by sweeping in forest, January 19, 1913. 
Habitat: Magnetic Island (Townsville), Queensland. 
Type: No. Hy 1739, Queensland Museum, the above specimen on a slide (mounted with 
three females of A. pulchriceps Zehntner from Java). 
Respectfully dedicated to Hugo Grotius.
