AUSTEALIAN EYMENOPTEBA CHALCIDOIDEA, IV.—GI$AULT. 273 



a dot at center of scutellum at meson, an elongate dot on median line of same at proximal 

 third and a shorter one at distal third; cephalic and caudal margins of propodeum very 

 narrowly; center of immediate base of abdomen; four marginal dots on abdomen along 

 proximal half and a marginal dot a little distance proximad of tip; opposite the four proximal 

 marginal dots a cross-stripe of which the distal three are double, the first of the couplets 

 much more distinct, the stripes not quite reaching the marginal dots; a fifth, unpaired and 

 faint stripe just caudad of the others but farther away from the fourth than the first four are 

 from one another; stripes 2-4 connected very narrowly along the meson. Thorax and vertex 

 with scattered black setea. First abdominal stripe faint. Thorax scaly. Mandibles tridentate. 



From one female caught sweeping grass in forest, April 6, 1914. 

 Habitat: Gordonvale (Cairns), Queensland. 



Type: No. Hy 2669, Queensland Museum, Brisbane, the specimen on a tag; head, middle 

 and hind tibia on slide with type of immaculatti<entris Girault. 



17. GYROLASELLA BIOCULATIVENTRIS new species. 



Female: — Length, 0.93 mm. 



Like Zagrammosoma pulchra Girault but the wings all hyaline, the legs all white except 

 hind coxa and proximal half of hind femur, the sides of the other coxas metallic ; the head white 

 except occiput and cheeks; at meson of vertex caudad, the white descending a short distance 

 into the occiput. The abdomen bears a large eye-spot on each side at margin a little distad 

 of middle and between these and base two obscure transverse white dots in a line longitudinally, 

 the distal one somewhat larger. Some ivory white around the axilla and tegula. The rather 

 long stigmal vein a little darkened. Scape white, antennae black; funicle 2 a little wider than 

 long, 1 somewhat longer than the pedicel. Mandibles tridentate. Two ring-joints. 



From one female captured by sweeping grass and foliage in forest, January 29, 1913. 



Habitat: Townsville, Queensland. 



Type : No. Hy 2670, Queensland Museum, Brisbane, the specimen on a slide. 



18. GYROLASELLA HOPKINSI new species. 

 Female: — Length, 1.05 mm. 



Like worcesteri Girault but the large conically acuminate marking of scutum plainly 

 reaches the caudal margin (in the other species barely so), the propodeum is wholly dark 

 metallic green except for a transverse, narrow wedge on each side of postscutellum, the mesal 

 margin of each parapside is metallic except at extreme caudal end; and the abdomen bears 

 long, abbreviated stripes, nearly confluent longitudinally and there are three transverse, 

 disconnected marginal dashes (and a fourth minute one caudad). Differs from pulchra in 

 being much less robust, in bearing the metallic coloration on the parapsides and having the 

 marking on the scutum subacutely pointed (as in channingi) and in the large abdominal 

 cross-stripes. In pulchra the stripes on the abdomen are not plain but more or less emarginated, 

 fluted or curved. Ocelli in green areas and cephalo-ventrad of the lateral ocellus, there is a 

 green mark, more or less elongate. In worcesteri, the valves of the ovipositor are extruded 

 but shortly. Pedicel above at base and sides of scape washed with metallic green. Mandibles 

 tridentate. 



From one female caught in forest, March 21, 1913. 



Habitat: Gordonvale (Cairns), Queensland. 



Type: No. Hy2671, Queensland Museum, Brisbane, the above specimen on a slide.
