MEMOIRS OF THE QUEENSLAND 2irSEUM. 
EUCCELOCYBOilYIA uew genus. 
Like Ceelocyhomyia Girault but metallic, the antennal club only 2-jointed, the antennse 
12-,jointed. The marginal vein is soraendiat longer than the postmarginal which is long and 
slender, subequal to the stigmal vein. The jjostscutellum is longer than with the other genus, 
triangular and as long as wide (much wider than long in Coelocyhomyia) while the propodeum 
bears a distinct median carina. Also, the pedicel is slmit, not long as in the other genus. 
1. EUCCELOCYBOMYIA AEREA new species. Genotype. 
Female: — Length, 1.85 inm. 
Dark metallic green, the scutellum mneoiis, the fore wing with a stain just under the 
stigmal vein; tegiihe and legs deep golden yellow, the hind coxa and femur metallic green. 
i>cape and pedicel metallic; rest of antenna) golden yellow. Margin of eyes dorsad and face 
golden yellow. Thorax finely, transversely reticulated, the scutelhim shining but polygonally 
reticulated.' Mesoj>ostsciitclium .subcoiucal, triangular. Propodeum ■with a distinct median 
carina, glabrous discally cejdialad. Abdomen depressed but conical, as long as the I’cst of the 
body, coppery, coarsely scaly, the incisions smooth. Pedieid short, the funicle joints all trans- 
verse. Otherwise as in the type species of Cirlocyhomyia. 
Described from one female reared from galls on young gum, March. 1911 (F. P. Spry).

Genus CtEIXlCYBELLA Girault. 
Head normal, rounded; vortex ])road; lateral ocelli distant from the eyes. Antenna) 
inserted near middle of face, slenderly clavate. 13-jointed with three ring-joints, five funicle and 
three club, all wider tJian long except distal joint of club; pedicel long obeonic, as long as the 
four joints following (ring-joints and ])roxiTnal funicle joint). Occi[»ital margin obtuse; 
})rothorax conical, short; mosos(nituiu with complete, distinct para[)sidal furrows, the scutiini 
slightly longer than the nugrooved scutolliim. Propodeum nith a very weak median carina, the 
spiracles moderate in size, rouml : i.o lateral carime nor suh'i. .Vbdomen sessile, depressed, about 
as long a.s the thorax, the second segment a third its length; ovipositor not e.xserted; a])domen 
from dorsal aspect ovate, widest about tlie middle, wider thou the thorax. Subnuirginal vein 
unbroken, at least two and a half times longer than the marginal, the latter nearly twice the 
length of either stigmal or postmarginal, Imth of which, for tlicm, are moderately hmg; stigmal 
vein with a rather large, rounded kmtb.and a distijict neck which is us long as the diameter of 
tlie knob. Discal cilia dtn.se and fine, the marginal very short. Tarsi 5-jointed; tibial s])urs 
double and very unet|ual, the intoruu'diate longer one very long, the ])()Steriov ones short, one 
much smaller and obscure, Nonmctallic, marked with yellow, the wings hyaline. Axilla' 
separated by a short distance, ^laiidibles bidentate, the second tooth truncate, unequal in the 
two mandibles.
