PHASNODISCOIDES new genus. 
1. PHZENODISCOIDES AUSTRALIENSIS new species. Genotype. 
Female :—Length, 1.60 mm, 
Bluish black, the legs yellowish brown, the coxe pale, the hind femora pale proximad, 
washed with bluish along distal two thirds; axille meeting inwardly, reddish brown. Wings 
sooty, with a dirty appearance, clear as far out as the bend of the submarginal vein. Antenna 
12-jointed with a very short ring-joint, the 3-jointed club and the distal funicle joint white, the 
rest black except the yellow-brown scape; first two funicle joints longest, subequal, each a little 
longer than the pedicel, cylindrical. Teeth of mandibles subequal, strong but not very long. 
Postmarginal and stigmal veins equal, each about a third shorter than the marginal. An obscure, 
oblique hairless line from the base of the stigmal vein. Propodeum with a median ¢arina, 
opaque, not sculptured, the thorax finely reticulated but the scutellum smoother distad. Head 
- impunetate or nearly, with an obtuse ridge between the antenne. Frons moderate. Palpi white. 
Funicle 1 nearly thrice longer than wide. 
Habitat: Gordonvale (Cairns), Queensland. Forest, April 27, 1913. 
Type: No. Hy 2979, Queensland Museum, Brisbane, the above specimen on a tag, the 
head on a slide. 
CERCHYSIELLA new genus. 
Seemingly closely allied with Cerchysius Westwood, the mandibles long and slender, the 
two outer (lateral) teeth long and subequal, each over twice the size of the third but the 
postmarginal vein is hardly developed, very much shorter than either the marginal or stigmal 
veins which are not very unequal, the marginal vein about thrice longer than wide, the stigmal 
a little longer than it. Also, the mesonotum is densely coriaceous, the scutellum glabrous, the 
axille shining but finely reticulated, meeting inwardly. Funicle joints distad of 1 a little 
wider than long, the club wider than the funicle and about haif its length. Head rounded, the 
frons moderately broad, the face inflexed, the cheeks two thirds the length of the eyes. Hind 
tibia with two spurs. Fore wings with an oblique hairless line. Valves of the ovipositor slightly 
exserted. Antennw 12-jointed, one very short ring-joint. 
1. CERCHYSIELLA NIGRA new species. Female. Genotype. 
Length: 1.60 mm. 
Black, lustrous, the wings hyaline; distal half of tibize and the tarsi reddish brown on the 
intermediate legs, the tarsi and tips of tibiz in other legs pale yellowish. Pedicel a half 
longer than thick at apex, longer than the first funicle joint which is a little longer than wide. 
Funicle 6 wider than long the joints widening a little distad. Third mandibular tooth acute, 
not truncate as in nigrella. 
Habitat: Gordonvale (Cairns), Queensland. Jungle, May 25, 1913. 
Type: No. Hy 2980, Queensland Museum, Brisbane. 
2. CERCHYSIELLA NIGRELLA Girault. Female. 
Length, 1.60 mm. 
The same as nigra but the mandibles are somewhat stouter and the third tooth not so 
well developed being in fact very short and truncate against the side of the middle tooth; the 
first funicle joint is distinctly longer than wide, three-fourths the length of the pedicel (in 
nigra funicle 1 is nearly quadrate and not more than half the length of the pedicel). The 
funicle joints are all stouter. Hind tibia with two spurs. The two outer teeth of mandibles are 
jonger and stouter than in the genotype. Apex of distal club joint white. 
Habitat: Halifax (Ingham) Queensland. February 25, 1913. 
Type: No. Hy 2981, Queensland Museum, Brisbane.
