tibial spurs slender, nearly colorless. Mandibles tridentate, the inner tooth shorter and rather 
broadly truncate. Thorax densely, finely scaly. Propodeum without a distinct median impres- 
sion, scaly and finely rugulose, brown. Propleurum suffused with yellowish.

2. XANTHOSOMA PULCHRICORPUS new species. Female. 
Length, 2.20 mm. 
Honey yellow, the dorsum of the abdomen with broad nearly confluent black stripes 
across it, the scutellum and propodeum black, also the area bounded by the ocelli and a large 
rounded spot at base of scutum centrally. Wings hyaline. Antenne and legs honey-yellow. 
~ First funicle joint subequal to the pedicel which is fuscous; club only 2-jointed, apparently 
3-jointed. Marginal vein stout; fifth segment of abdomen a half or less longer than the 
fourth. Propodeum with a distinct median channel with carinated sides. Hind tibie with 
two spurs. Margins of scutellum yellow, also segment 2 of abdomen, the latter glabrous. 
Funicles 2-5 wider than long. 
Habitat: Magnetic Island, Townsville. Forest, January. 
Type: No. Hy 3262, Queensland Museum, Brisbane, the female on a tag, a caudal tibia 
and portion of an antenna on a slide. 
8. XANTHOSOMA HAECKELI new species. Female. 
Length, 1.60 mm. 
Black, the wings hyaline; legs and petiole straw yellow; abdomen at base above (most 
of segment 2), beneath and along sides at proximal half, sides and venter of thorax (except 
the last region), parapsides and axillze (both the latter darker), reddish yellow. Thorax rather 
densely finely reticulately lined, the propodeum with a broad, scaly, longitudinal mesial path, 
not impressed, limited laterad by a distinct carina; rest with several irregular ruge. Face 
and cheeks lemon yellow; antennz black, the scape yellow, funicle joints all somewhat wider 
than long, except the first which is subquadrate, subequal to the pedicel. Second tooth of 
mandible broadly, concavely truncate, nearly forming two teeth. One spur of hind tibia 
much shorter. Antenne 9-jointed, the club not truly divided in the usual place; one ring- 
joint. Propodeum sparsely rugulose. Fifth abdominal segment somewhat the longest. Post- 
marginal vein a little shorter than the stigmal which is a half shorter than the somewhat 
thickened marginal. Petiole somewhat longer than wide. Seutum and scutellum with a 
aumber of obscure pustule-like punctures. 
Habitat: Gordonvale (Cairns), Queensland. Jungle, June 5, 1913 (A. P. Dodd). 
Type: No. Hy 3263, Queensland Museum, Brisbane, the female on a tag and a slide 
bearing the head and a hind leg. 
GENUS AXANTHOSOMA Girault. 
Like Xanthosoma Ashmead but the abdomen plainly twice the length of the head and 
thorax combined. Allied with Aximogastra Ashmead but abdominal segments less equal, the 
abdomen beyond the seventh segment produced into a thin setiform process as long as the 
head and thorax combined; segments 5 and 6 are about equal, long, each about twice the 
length of 4. Head and thorax not umbilicately punctate only finely transversely wrinkled. 
Stigmal and postmarginal veins unequal. Segment 6 of abdomen a little longer than segment 
5. Hind tibize with two spurs. First funicle joint longer than the pedicel, only about two 
thirds the length of the scape; a few scattered thimble punctures on the propodeum. Antenne 
10-jointed.
