132 MEMOIRS OF THE QUEENSLAND MUSEUM. 
3. ENCYRTOMYIA ALBITARSUS new species. 
Female :—Length, 0.75 mm. 
Dark metallic green, the wings hyaline; funicle and club yellowish white; tarsi, tips of 
first two pairs of femora, knees, cephalic tibiz except centrally, middle tibiz except a rather 
wide band some distance below knee (midway between knees and the middle point of those 
tibie) and hind tibiew, white. Scutellum longitudinally, finely lined; scutum densely scaly. 
About four rows of coarser cilia proximad of the oblique hairless line. Funicle joints all much: 
wider than long, much shorter than the pedicel, widening distad but the first funicle joint is a 
little longer than wide; a minute ring-joint present. Agreeing with the description of 
Omphalencyrtus. Scape distinctly dilated for its entire length, the mandibles truncate. Frons 
a little narrowed (over six times the diameter of an ocellus). Stigmal vein very short, the 
postmarginal subobsolete. 
From one female caught July 14, 1912, on forest-downs. 
Habitat: Hughenden, Queensland. 
Type: No. Hy 3060, Queensland Museum, Brisbane, the specimen on a tag. 
Very similar indeed to albiflagellum but the pedicel is paler and the frons distinctly 
narrower. 
4. ENCYRTOMYIA AUSTRALIS new species. 
Female :—Length, 1.05 mm. 
Dark metallic green and scaly, the wings hyaline, and with an oblique hairless line. 
Agreeing with Plagiomerus diaspidis Crawford but the pedicel at proximal half dusky, the 
first funicle joint is longer than wide, the second transverse, shortest, the third a little longer 
than it while the fourth is the next longest of the four yet wider than long; pedicel over half 
the length of the funicle; the three club joints subequal in length. Marginal vein rather thick, 
longer than wide. Mandibles short, truncate, one edentate, the other with a small outer tooth, 
the inner broadly truncate. Antenne 10-jointed. Club long. 
From one female captured by sweeping the foliage of lantana, October 20, 1911. The 
mandibles in this species are anomalous. r 
Habitat: Mackay, Queensland. 
Type: No. Hy 3061, Queensland Museum, Brisbane, the head ot above specimen on a 
slide with Sympiesomorphelleus suttneri Girault. 
5. ENCYRTOMYIA VIRIDISCUTELLUM new species. 
Length, 0.98 mm. 
Very dark metallic blue-black, the seutellum contrasting, rather bright metallic green;, 
knees, tips of tibiz (all of intermediate tibiz except below knee) and tarsi straw yellow,. 
also the funicle and club; the scape and pedicel black, the former white at distal third, the 
latter around apex. Antenne with a very thin ring-joint. Teeth of mandibles not developed; 
scape slender, the pedicel elongate and slender. Thorax with a dense, minute sealy sculpture.. 
Funicle as figured for the genotype of Psylledontus, the club appearing solid. 
Habitat: Gordonvale (Cairns), Queensland. Jungle, November 1, 1913. 
Type: No. Hy 3062, Queensland Museum, Brisbane, a female on a tag, the head on a 
slide. A second female caught by sweeping mangroves, bank of Tweed River, Chindera, New 
South Wales, May 14, 1914 (A. P. Dodd). 
TRIBE ECTROMINI. 
The table of genera given at the end of this tribe has been followed. It was compiled 
from original sources as much as possible, mainly from Foerster, Mayr and Ashmead. The 
latter in his table of genera, makes the principal division on too variable a character—the
