EUCfELOCYBOMYIA new genus. 



Like Ciielocyhomyia tiirault but metallic, the antennal club only 2-jointe(3, the antennsB 

 12-jointecI. The marginal vein is somewhat longer than the postmarginal which is long and 

 slender, subequal to tlie stigmal vein. The postscutellum is longer than with the other genus, 

 triangular and as long as wide (niuoh wider than long in Ccelocijhomiiia) while the propodeum 

 bears a distinct median carina. Also, the pedicel is shjit, not long as in the other genus. 



1. EUCffiLOCYBOMYIA AEREA new species. Genotype. 

 Female: — Length, l.S.j mm. 



Dark metallic green, the scutellum yneoiis, tlie fore wing with a stain just under the 

 stigmal vein; togula; and legs deep golden yellow, tlie hind coxa and femur metallic green. 

 Scape and pedicel metallic; rest of antennae golden yellow. Margin of eyes dorsad and face 

 golden yellow. Thorax finely, transversely reticulated, the scutellum shining but polygonally 

 reticulated. Mesopostscutellum subconieal. triangular. Propodeum with a distinct median 

 carina, glabrous discally cephalad. Abd(mien depressed but conical, as long as the rest of the 

 body, coppery, coarsely scaly, the incisions smooth. Pedicel short, the funicle joints all trans- 

 verse. Otherwise as in the type species of Co'locyhomi/Ui. 



Described from one female reared from galls on young gum. March. 191V (F. P. Spry).

GENU.S C(KL()('YBELLA GirauU. 



Head normal, rounded: vertex liroad; lateral ocelli distant from the eyes. Antenuai 

 inserted near middle of face, slenderly clavate. 13-jointed with three_riiig-joints, five funicle and 

 three club, all wider than long except distal joint of club; pedicel long obconie, as long as the 

 four joints following (ring-joints and proximal funicle joint). Occipital margin obtuse; 

 prothorax conical, short; mesoscutum witli complete, distinct parapsidal furrows, the scutum 

 slightly longer than the uugrooved scutellum. Projiodeum with a very weak median carina, the 

 spiracles moderate in size, round ; no lateral carina- nor sulci. Abdomen sessile, depressed, about 

 as long as the thorax, the second segment a tliird its length; ovipositor not exserted; abdomen 

 from dorsal aspect ovate, widest about the middle, wider than the thorax. Submarginal vein 

 unbroken, at least two and a half times longer tlian the marginal, the latter nearly twice the 

 length of either stigmal or postmarginal, both of which, for them, are moderately long; stigmal 

 vein witli :i rather large, rounded knob and a distinct neik wliich is as long as the diameter of 

 the knob. Uiscal cilia dense and fine, the marginal very short. Tarsi .'j-jointed; tibial spurs 

 double and very unequal, the intermediate longer one very long, the posterior ones short, one 

 much smaller and obscure. Nonmetallic, nmrked with yellow, the wings hyaline. Axilla^ 

 se|>arated by a short ilistance. ^landibles hidcntato. the second tooth truncate, unequal in the 

 two mandibles.
