AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, XII—GIRAULT. 295 
bearing also sparse, long, yellow-white hairs, the upper sides of the propodeum also thus 
clothed. Scape subobclavate, the pedicel longer than any of the funicle joints of which the first 
three are longest and subequal, the distal one plainly wider than long. 
Habitat: Gordonvale (Cairns), Queensland. Associated with a cecidomyiid gall on 
Careya australis. 
Type: No. Hy 3324, Queensland Museum, Brisbane, the female on a tag. 
2. NEOMEGASTIGMUS COLLARIS new species. Female. 
Length, 1.35 mm., excluding the ovipositor which is extruded for a length about 
equal to that of the abdomen. 
Like lividus but the ovipositor is extruded for a shorter distance and the pronotum is 
pale orange; also the legs are whiter. Head dark orange yellow. Abdomen subsessile. 
Habitat: Thursday Island, Torres Strait. Forest in March. 
Type: No. Hy 3325, Queensland Museum, Brisbane, the female on a tag and a slide. 
38. NEOMEGASTIGMUS PETIOLATUS new species. Female. 
Length, 1.95 mm., excluding the black extruded valves of the ovipositor which are 
about two thirds the length of the abdomen. 
Orange yellow, the abdomen (its short, distinct petiole pallid), propodeum and distal 
third of seutellum lightly purplish black. Fuscous spot from stigma large, nearly a band 
across the wing. Caudal margins of segments 2-4 of abdomen incised at meson, the incision 
large, wide on segment 2, minute on segment 4. Cephalic legs (femur and distad) pale, the 
others concolorous with the abdomen but all tarsi pale, the antenne straw yellow. Funicle 
joints all shorter than the pedicel. Thorax densely reticulated and transversely lineolated. 
Habitat: Mackay, Queensland. Open fields in October. 
Type: No. Hy 3326, Queensland Museum, Brisbane, the female on a tag. 
A second female from the foliage of Tristania, September 3, 1913 at Gordonvale 
(Cairns), Queensland (E. J. Girault). 
4. NEOMEGASTIGMUS FILIUS new species. Female. 
Length, 2.50 mm., excluding extruded part of ovipositor which is a little longer than 
the abdomen. 
Like collaris but much more robust, the ovipositor longer than the abdomen and the 
legs differ in that the coxw and the hind femora are brown. The nearly black dash from the 
stigma is longer and somewhat curved. The proximal funicle joint in this species is plainly 
longer than wide, 1-3 subequal, the others shortening somewhat, the distal funicle joint a 
little longer than wide. Pedicel slightly longer than the distal funicle joint. In collaris all 
the distal funicle joints are subquadrate, barely longer than wide and distinetly shorter 
than the pedicel, the distal funicle joint a little wider than long. The caudal margin of the 
pronotum in both species is concolorous with the scutum. 
Habitat: Gordonvale (Cairns), Queensland. December 19, 1911. 
Type: No. Hy 3327, Queensland Museum, Brisbane, the female on a tag, the head with 
the slide type of collaris. 
5. NEOMEGASTIGMUS SALTENSIS new species. Female. 
Length, 1.50 mm., excluding ovipositor. 
Like lividus Girault but the femora also concolorous and the extruded portion of the 
valves of the ovipositor are slightly shorter than the abdomen. Funicle joints 1-4 subequal, 
each barely longer than wide, the remaining widening and shortening a little in succession, 
joint 7 a little wider than long. Scutellum simple as with the other species. Propodeum not 
plainly seen. Pedicel distinctly longer than any of the funicle joints.
