GEeNus LISSEURYTOMA Cameron. 
‘* Marginal vein thrice longer than the stigmal, postmarginal shorter than the latter, 
the stigmal branch as long as stigmal, its apex slightly thickened, oblique. Head and thorax 
not umbilicately punctate, smooth, parapsidal furrows distinct; scutellum large, narrowed 
toward base, the apex broadly rounded, margined by a keel. Abdomen with the basal segment 
sessile, longer than any of the others, the second to fifth of almost equal length. Metanotum 
flat, triangular, its sides stoutly keeled, the middle with two fine keels. Eyes ovate, the lower 
side more sharply pointed than the upper; malar space two thirds of their length. Antenne 
12-jointed, stout, third joint conical, longer than wide, fourth and fifth as wide as long, the 
others wider than long. Legs stout, hinder tibize with one spur. 
The thorax is longer than usual, but not the pronotum; it is fully one-half longer than 
the abdomen; the flattened, only slightly sloped metanotum adds to its length. The head is 
transverse behind; the temples are very slightly developed. The ocelli are in a wide triangle, 
in almost a curve. 
A distinct genus. The single spur on the hind tibizw separates it from all the other 
described genera, except Phylloxeroxenus, but that has the thorax umbilicately punctate. The 
pronotum is not quite so largely developed as it is in Hurytoma, and is more distinctly narrowed 
at the base.’’ 
1. LISSEURYTOMA VIOLACEITINCTA Cameron. Male. Genotype. 
Length, 4 mm. 
‘*Black, abdomen distinctly violaceous, base and apex of tibizw obscurely, and tarsi, 
testaceous; wings hyaline, nervures black, an obscure cloud, of transversely oval shape before 
the stigmal branch. Pro- and mesothorax opaque, pro- and mesonotum very closely, finely, 
transversely striated in front. Metanotum smooth shining. 
The hair on the legs and metapleure is longer than elsewhere; that on the legs is long, 
white and sparse. Hind tibie flattened, broader than the others; metatarsus as long as 
second and third joints united, and a little shorter than the apical. The apex of the antennal 
scape does not reach much beyond the middle of front, nor do the antennal depressions. 
Habitat: Gosford, New South Wales.’’ 
GENUS SYSTOLE Walker. 
1. SYSTOLE KOEBELEI Ashmead. ‘Female. 
Length, 2.5 mm. 
Robust, brownish yellow and sparsely pubescent; stemmaticum, occiput, pedicel of 
antenne, except narrowly at apex, anterior margin of mesonotum and sutures dividing sclerites 
of thorax, black. Wings hyaline, pubescent, the veins brown, the subcostal vein interrupted 
by a white bulla at its junction with the marginal vein; marginal and postmarginal veins 
about equal, longer than the stigmal. Head viewed from above subglobose, with scrobes deep 
and extending nearly to front ocellus; pedicel obconical, twice and one half longer than thick 
at apex; flagellum clavate, first three joints very small, together shorter than the pedicel 
and very much narrower, moniliform, the joints beyond widening and wider than long. 
Thorax rugulose, except the black anterior portion of mesonotum which is smoother but with 
delicate transverse aciculations. Abdomen oval, finely coriaceous and sparsely pubescent, the 
segments after the second subequal in length. 
Habitat: Australia.

2. SYSTOLE OPUS Girault. Female. 
Length, 1.10 mm. 
Black, the wings hyaline, the antenne concolorous, also the coxe and most of all femora 
the tibie and tarsi yellowish brown; third and fourth abdominal segments smooth, the next
