AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, VII.—GIRAULT. 171 
2. TETRACNEMELLA VIRIDISCUTELLUM new species. 
_ Female :—Length, 0.85 mm. Differs from the preceding principally in having the frons 
broad. 
Dark metallic blue, the wings hyaline, the scutellum contrasting green; knees, tarsi, 
tips of tibie (all of middle tibize except just below knees), yellowish; funicle and club 
whitish, also tips of pedicel and scape. Head and thorax densely scaly. Funicles 1 and 4 
shortest, all the others short, subquadrate, 4 a little wider than long; pedicel distinctly longer 
than any of the funicle joints; club a little over half the length of the funicle. Scutum with 
soft scattered pilosity. Axille not greatly separated. Stigmal vein twice the length of the 
marginal which is quadrate and subequal to the postmarginal. Otherwise as in the preceding. 
From one female taken by sweeping in forest, December 25, 1912. 
Habitat: Capeville (Pentland), Queensland. 
Type: No. Hy 3145, Queensland Museum, Brisbane, the specimen on a tag; head, hind 
wing and hind legs on a slide. 
38. TETRACNEMELLA MINUTELLA new species. 
Female :—Length, 0.85 mm. 
Dark grass green, metallic, the wings hyaline, the venation, knees, distal half of cephalic 
tibiw, distal three fourths of middle tibix, tips of caudal tibiz, tarsi and tegule pale yellowish 
brown. Funicle yellowish brown, the club a little darker, the pedicel and scape dark metallic 
green. Abdomen dark, shorter than the thorax. Funicle joints subequal but widening a little 
distad. Frons moderately narrow. Venation as in viridiscutellum and resembles that species 
closely but in the head it is like australiensis except that the frons is subprominent. Differs 
from viridiscutellwm in having the cephalic tibiz# mostly yellowish, the scape and pedicel wholly 
dark metallic, the frons is narrower, the thorax is a trifle more densely, finely scaly. Scutum 
and seutellum large in both species, the scutellum extending to base of abdomen. 
From one female caught on forest uplands, May 3, 1914 (A. P. Dodd). 
Habitat: Tweed Heads (Tweed River), New South Wales. 
Type: No. Hy 3146, Queensland Museum, Brisbane, the specimen on a tag; head, a 
hind leg and a fore wing on a slide. 
PARECTROMOIDES new genus. 
Female:—In the table of genera runs to Eeclromoides Girault but differs in that the 
marginal vein is longer than either the postmarginal and stigmal which are subequal and rather 
long, the venation as in Hurytoma. Also, the scutellum is larger, extending to base of abdomen. 
The marginal vein is five or more times longer than wide. Scrobes long, separated by a median 
ridge from between base of antenne. rons moderately narrow. Mandibular teeth a little 
unequal, acute. Flagellum capitate, the funicle cylindrical, the scape long and slender, longer 
than the club which is about two thirds the length of the funicle. Cheeks about as long as the 
eyes. Ovipositor distinctly shortly extruded. Club long-ovate. Thorax convex, not flat as in 
Ectromoides. Cephalic legs compressed. 
1. PARECTROMOIDES MAGNISCUTELLUM new species. Genotype. 
Female :—Length, 1.50 mm. Stout. 
Dark purple, the abdomen dark green, the extruded valves of ovipositor and antennz 
(except the brownish yellow apical end of scape) black. Seutum with an obscure silvery stripe 
across caudal edge. Fore wings with a distinct yellow stain from whole of the marginal vein 
two thirds the way across the caudal margins and diffused distad under the stigmal vein, the 
venation yellow. Legs concolorous except tarsi, tips of tibiz, distal half of caudal femur, 
caudal two pairs of knees, distal half of middle tibizw and all of, caudal tibiz, which are rich 
yellowish brown. Frons with a double row of fine punctures along the eyes, otherwise scaly.
