AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, XIII.—GIRAULT. 311 
1. PLEISTODONTES IMPERIALIS Saunders. Genotype. 
Habitat: Australia. Fruit of Ficus macrophylla. 
2. PLEISTODONTES NIGRIVENTRIS new species. Female. 
Length, 2.20 mm., excluding ovipositor which is exserted for a length about equal to 
that of the abdomen. Head not quite twice longer than wide. Postmarginal vein longer than 
the stigmal, the latter long. 
Orange yellow, the posterior margin of the head, flagellum, all of abdomen except at 
base, an hourglass-shaped marking down meson of pronotum and cephalic part of scutum (a 
smaller end cephalad; shaped like an inverted eggcup), a stripe across apex of thorax (about 
apex of scutellum), the tegule and a dot in a line longitudinally with them, cephalad (opposite 
the apex of the eggcup-shaped marking), jet black; also the valves of the ovipositor. 
Mandibles bidentate at apex (but 5-dentate), the antenne 11-jointed without a ring-joint, the 
scape hemispherically dilated (foliaceously). Third and fourth funicle joints subequal, longest, 
Jonger than the pedicel which is subequal to the distal funicle joint. Postmarginal vein 
longer than either marginal or stigmal, the latter shortest. Wings hyaline. Body glabrous. 
Pedicel wider than long; funicle 1 with the process which encloses 2, the latter longer than 
wide. 
Habitat: Mount Tambourine (type), Queensland and Tweed River, New South Wales. 
Type: No. Hy 3360, Queensland Museum, Brisbane, the female on a tag, the head on 
a slide. 
CERATOSOLENSIA new genus. 
Female :—Agreeing with Ceratosolens Mayr but the antenne are only 10-jointed, the 
club 2-jointed, the last two funicle joints wider than long, no ring-joints; first funicle joint with 
a sheath-like process. Mandibles bidentate, the appendage serrate. Marginal, stigmal and 
postmarginal veins subequal. Spiracular fovea long, gougelike. Head somewhat longer than 
wide, without a tuberele. Ovipositor as long as the thorax and abdomen together. 
Male :—Differing from Ceratosolens in that the antenne are only 4-jointed. Mandibles 
strongly bidentate. 
Type: The following species. 
1. CERATOSOLENSIA FICOPHAGA new species. 
Female :—Length, 1.60 mm. Fore wings very broad. 
Shining black, the distal third of the abdomen and the head suffused with brown. Wings 
hyaline. Legs yellow, the antenne brownish, the scape and pedicel darker. Fourth funicle 
joint longest. Body glabrous. Parapsidal furrows subobsolete caudad. Vertex and center 
of face yellowish. Pronotum pubescent. Intermediate femur dusky centrally. 
Male :—Length, about-3 mm. Apterous and normal for the subfamily. 
Rich yellow, the head chestnut brown, the pronotum brownish. Antenne and legs con- 
colorous with the head and body respectively but the former with extreme tip pale yellow; 
the antennz lie for nearly their entire length in what appears to be a closed canal; the first 
joint is stout, the second shortest, subequal in width to the two following, the third longest 
but not much longer than the fourth and last which is somewhat longer than the first; the 
second joint is only about two thirds the length of the first. Types re-examined. 
Described from several dozen specimens of each sex taken from a partly ripe fig, jungle, 
September 18, 1912. Also in January.
