AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, XI.—GIRAULT. 261 
1. CHROMEURYTOMA CLAVICORNIS Cameron. Female. Genotype. 
Length, 4.5 mm. 
““ Dark green, largely tinted with blue, and to a less extent, with violaceous; antennz 
sind legs, except the cox, rufo-testaceous; mandibles and palpi testaceous; wings hyaline, 
nervures pale testaceous. 
Vertex below the ocelli finely, closely striated; apex of pronotum, mesonotum and 
scutellum finely, closely striated, the striation stronger on the scutellum, weaker on the base 
of mesonotum; postscutellum microscopically striated, the parts bordering it fiery-red. 
Metanotum smooth. Metapleure fiery-red. Abdomen smooth. Apex of pronotum narrowly 
fiery-red. There is a wide curved furrow on the malar space. Ventral surface of the abdomen 
Jargely violaceous. 
I am not sute but that the deep rufous tint of the legs may be caused by discoloration 
through the action of cyanide of potassium.’’ 
This is probably one of the gall-inhabiting Perilampide. 
GENUS XANTHEURYTOMA Cameron. 
‘* Submarginal vein twice the length of the marginal, thickened toward apex, marginal 
thickened, postmarginal not one half the length of marginal, not longer than stigmal, which 
is triangularly thickened at base, at its junction with the marginal, the lower part of it 
narrowed, roundly curved. Antenne 11-jointed, short, thick, joints of flagellum wider than 
thick, not distinctly separated, at the most only pilose; the scape narrower than flagellum and 
does not extend much above the middle of the eyes; there is no clear club to the antenne; the 
front is not much depressed. 
Ocelli almost in a straight line, the central very little in front of the lateral. Parapsidal 
furrows clearly defined, rounded, meeting very shortly before base of scutellum. Scutellum 
large, longish-pyriform, the broad end at the apex; almost as long as the mesonotum. 
Metanotum short, steeply oblique; the centre with a keel on one side, the two parallel, not 
converging. Thorax not punctured, only very finely striated above. Abdomen sessile, distinctly 
shorter than thorax; its second segment much longer than the others; its apex bluntly 
rounded, broad; fifth segment shorter than fourth. 
Comes near to Xanthosoma Ashmead which may be known from it by the fifth 
abdominal segment in the female being nearly twice as long as the fourth, by the abdomen 
being longer than the thorax, and by the marginal vein being one and a half times, not twice 
longer than the stigmal. The parapsidal furrows are deeper, more clearly defined and more 
roundly curved than in Hurytoma; the seutellum is larger and much more narrowed at base 
than in that genus.’’ 7 
1. XANTHEURYTOMA FLAVA Cameron. Male. Genotype. 
Length, 2 mm. 
““Vellow; back of thorax deeper, more fulvous in tint; centre of the whole of basal slope 
of pronotum and the thoracie sutures more or less black, flagellum of antenne tinged with 
fulvous, legs a paler yellow than the body; wings hyaline, nervures testaceous, the dilated 
parts darker colored; stigmal vein triangularly dilated at base, the apical part a little longer 
than it, roundly curved. The metanotum and back of abdomen may be infuscated. 
Occiput transverse, infuseated, more or less obscurely striated. Hinder ocelli separated 
from each other by twice the distance they are from the eyes. Mesonotum and scutellum finely, 
closely, transversely striated. Parapsidal furrows distinct, roundly curved toward each other 
at apex, where they unite and are joined to the scutellar furrow by a short one. Scutellum 
large, ovate, twice longer than wide, obliquely narrowed to a point at the base, the apex broadly 
rounded. 
Probably a variable species, as regards the amount of black.’’ 
Probably a Taneostigmine.
