point; all of disk of pronotum; parapsidal furroAvs, except at each end; proximal two thirds 

 of median line of scutellum, the line swelling caudad; all of propodeum out to spiracle; six 

 distinct, but thin stripes across abdomen centrally, the stripes abbreviated laterad; and 

 four short transverse dashes or marks, non-co-ordinated with the cross-stripes, along abdomen 

 in the dorso-lateral aspect. Hind tibial spur distinct, rather stout. Mandibles tridentate, the 

 third tooth truncate and with indications of minute teeth. Postmarginal vein nearly as long 

 as the stigmal. 



Described from one female caught by sweeping in forest, December 2, 1912 (A. P. Dodd). 



Habitat: Northern Queensland (Gordonvale near Cairns). 



Type : No. Hy 2665, Queensland Museum, Brisbane, the above specimen on a tag, the

12. GYROLASELLA FESTIVA new species. 



Female: — Length, 2 nun. 



Bright lemon yellow, the legs and antenna? concolorous but the scape metallic green 

 along the dorsal edge. "Wings hyaline. Marked with brilliant metallic green as follows: A 

 line across neck of pronotum, one across the narrow pronotum appearing like the cephalic 

 margin of scutum; mesal margin of each parapside; a tau-shaped marking centrally on scutum, 

 the upright of the letter extending to caudal margin, the cross-piece at cephalic third; whole 

 of median line of scutellum, the green swollen somewhat centrally; a broad stripe across 

 cephalic margin of propodeum involving the spiracles; the connection between propodeum and 

 abdomen; five stripes across the latter from base to distal third, first stripe connected with 

 immediate base of abdomen at meson, stripes 2-4 connected along the meson, fifth stripe with 

 a short, cephalic projection at meson; a spot laterad of postscutellum ; a longitudinal line 

 on axilla and another in the vicinity of the tegula. Postmarginal vein nearly as long as the 

 stigmal. A green stripe across face from dorsal ends of eyes. Mandibles 6-dentate. Antenna? 

 dusky; funiele joints subquadrate. Ocelli in green areas. 



Described from one female reared from miscellaneous galls on Eucalyptus in forest, 

 October 7, 1913. 



Habitat: Northern Queensland (Gordonvale near Cairns). 



Type: No. Hy2666, Queensland Museum, Brisbane, the above specimen on a slide. 



13. GYROLASELLA IMMACULATIVENTRIS new species. 

 Female: — Length, 1 mm. 



Greenish yellow, the legs and antennae concolorous, the wings hyaline. The following 

 dark metallic green markings: A line connecting the ocelli; an oval dot on each caudo-lateral 

 angle of pronotum; a rather broad stripe across cephalic margin of scutum not extending 

 quite to margins on each side, its caudal edge emarginate at meson; a longer than wide spot 

 on parapside, caudo-mesal corner; a similar but smaller, oval spot on the axilla?, meso-cephalad, 

 abutting on to the marking on the parapside ; a small triangular spot center of base of 

 scutellum: another somewhat swollen one on propodeum about at the spiracle; a shallow 

 Y-shaped but conspicuous marking center of propodeum appearing like a bird with spread 

 wings; and a short longitudinal dash just mesad of tegula. Thorax densely scaly.
