3. LEPTOMASTIX TRIFASCIATIPENNIS new species. 
Female :—Length, 2.15 mm. 
Similar to the original description of trifasciatus but the pronotum is also golden yellow 
except across cephalic and caudal margins and down the meson narrowly; propleura golden 
yellow. Middle tibia in both species yellowish. Axille with a carina between them in both 
species and the scutum bears short silvery pubescence. In this new species maxillary palpi 
4-jointed, hind tibial spurs double, the two white stripes on fore wing nearly equal in length 
(proximo-distad). Proximal margin of third stripe triangularly produced. 
From one female caught by sweeping forest, May 27, 1914. 
Habitat: Gordonvale (Cairns), Queensland. 
Type: No. Hy 3104, Queensland Museum, Brisbane, the specimen on a tag with type 
trifasciatus; head, fore wing and hind leg on a slide. 
4. LEPTOMASTIX AURATICORPUS new species. 
Female :—Length, 1.35 mm. 
Bright golden yellow, the flagellum (excluding pedicel) and a conspicuous spot on the 
thoracic pleurum caudad, jet black. Bulle and dorsal edge of scape dusky black, the former 
long; scape extending to tip of vertex; pedicel twice longer than wide; funicie 1 six (or more) 
times longer than wide, twice the length of the pedicel, 3 and 4 subequal, a little shorter than 
1 or 2, 6 a little longer than the pedicel; club not as long as the scape. Fore wings hyaline 
but distinctly embrowned along each margin (all of caudal margin narrowly except at each 
end and the cephalic margin more broadly from venation to cephalo-distal apex); fore wings 
somewhat over thrice longer than wide. Frons and face coarsely scaly reticulate; thorax more 
finely so, the scutum with numerous, minute, setigerous punctures. Axille very narrowly 
separated by a short, narrow carina (same in trifasciatus); propodeum without a median 
carina. Propodeum and base of abdomen naked, not with silvery pubescence as in the 
genotype. Marginal vein normal, about three and a half times longer than wide, a little 
longer than the stigmal vein which in turn is a little longer than the postmarginal. Costal 
cell very narrow. Head (cephalic aspect) a little wider than long, the eyes large, the cheeks 
only about a fourth the length of the eyes; frons broad; lateral ocelli about as far from the 
cephalic ocellus as from the eye margins; face convex, head lenticular, the scrobes very short. 
Mandibles with two small acute teeth. Abdomen as in Hpidinocarsis, shorter than the slender 
fore wings but as long as the thorax. Hind tibial spurs double, very unequal. 
From one female taken by sweeping in forest, August 30, 1913 (A. P. Dodd). 
Habitat: Gordonvale (Cairns), Queensland. 
Type: No. Hy 3105, Queensland Museum, Brisbane, the specimen on a tag; head and 
fore wings, middle and hind tibiz# on a slide with fore wing of genotype. 
5. LEPTOMASTIX BICOLORICORNIS new species. 
Female:—Length, 1.80 mm. Wings shorter than the abdomen which is longer than 
the rest of the body and acute. 
Dark metallic purple, the wings hyaline, the cox concolorous, the iegs yellowish brown 
except the femora above and near base. Antenne black, scape at apex broadly, a silvery white 
stripe along each side of scape, proximal fifth of funicle 1 and proximal four fifths of funicle 
2, silvery white. Pedicel over thrice longer than wide at apex, somewhat over half the length 
of funicle 1 which is longest, somewhat longer than 2 or 3 which are elongate and subequal; 
funicle 6 somewhat less than twice longer than wide, somewhat shorter and thicker than the 
pedicel. Head with very fine surface sculpture and distinct, moderate-sized thimble punctures. 
Body similar to that of the genotype except that the abdomen is longer than the thorax, the 
propodeum lacks the median carine# and the scutellum and scutum also bear the silvery 
pubescence. Thorax minutely densely sheened; scutum with short silvery pubescence, the
