PARACALOCERINUS new genus. 
1, PARACALOCERINUS AUSTRALIENSIS new species. Genotype. 
Female :—ULength, 1.20 mm. 
Metallic purple, the scutellum and propodeum green; cephalic and intermediate tibiae 
pale brown, the hind tibiz whitish below the knees for some distance; tarsi pale brown. Fore 
wings brown from the bend of the submarginal vein to apex, the brown broken by a large, 
obliquely ovate white area at each wing margin and thus two opposite white areas, situated 
just a little distad of the apex of the venation. Stigmal and postmarginal veins short, the 
former a little the longer, the marginal vein long, four or more times longer than the stigmal; 
oblique hairless line distinct. Axille nearly meeting. Ovipositor valves black, extruded for a 
length equal to half that of the abdomen. Head and thorax with a fine scaly sculpture. 
Mandibles with two equal acute teeth. Propodeal spiracle minute, round. Antenne 9-jointed, 
the club solid, no ring-joint. Scape slender, the pedicel much longer than any of the funicle 
joints which are all much wider than long, and widening distad; scape without the bulla about 
as long as the funicle, the club more or less the same length. Frons moderately broad, the 
face inflexed. 
From one female captured by sweeping the forest floor, top of coast range of mountains 
(1,500 feet), May 26, 1912. ; 
Habitat: Gordonvale (Cairns), Queensland. 
Type: No. Hy 3086, Queensland Museum, Brisbane, the specimen on a tag; head on a 
slide. 
In a female from Gordonvale, January 1, 1913, caught by A. P. Dodd sweeping a jungle- 
clad forest streamlet, the middle tibia was lemon yellow. 
A female was caught in jungle, May, 1913, at the same place and another there in the 
forest on March 31, 1914, the latter with no trace of wings. Also, a normal female by sweeping 
grass in forest, Capeville, Pentland, Queensland, September 15, 1914. A female from Kuranda, 
Queensland, September 12, 1913 (A. P. Dodd). 
ECTROMELLA new genus. 
Female:—Head thin, somewhat longer than wide, the antenne 11-jointed, the funicle 
5-jointed, three club joints, one very short ring-joint; scape cylindrical. Wings hyaline, the 
marginal vein barely longer than wide, the stigmal short but distinctly longer than the marginal, 
the postmarginal nearly as long as the marginal, subobsolete; wings with an oblique hairless line. 
Axille barely separated. Abdomen pointed conic-ovate, the ovipositor not extruded. Form 
small, slender. The mandibles are very small, with two acute teeth. Frons narrow at upper 
face, rather broad caudad at occipital margin, the eyes rounded; cheeks long. Hind tibial 
spur single, the middle tibial spur over twice its size but not very stout. Oblique hairless line 
of fore wing obscure, apparently running along against the submarginal vein. Fore wings 
densely, very finely ciliate discally. Scutellum convexly rounded at apex.

Female :—Length, 0.65 mm. 
Dark metallic purple, the thorax mostly yellowish brown washed lightly with purplish, 
the pronotum and propodeum purple. Antenne yellowish brown, the pedicel as long as the 
first funicle joint which is twice longer than wide and distinctly longer than the other four 
joints of which 2 is shortest, somewhat shorter than 5 and narrowest; joints 3 and 4 subequal, 
each a fourth shorter than 1; club dusky, wider than the funicle. Thorax with a distinct scaly 
sculpture. Legs pale yellow. 7
