304 MEMOIRS OF THE QUEENSLAND MUSEUM. 



Fore wings with a black stripe across them at the bend of the submarginal vein. Scape com- 

 pressed; funicle 2 much wider than long, widest and shortest, 1 narrower than it but distinctly 

 wider than the ring- joint which is subquadrate. Funicle 6 largest, larger than the pedicel, 

 subquadrate, funicle 4 wider than long. Club as long as the scape. Mandibles bidentate, the 

 second tooth broad. Face obscurely reddish centrally. 



Male: — Not known. 



Described from sis females on a card in the collections of the National Museum of 

 Victoria, Melbourne, labelled "24 and 25, 06-9-11, nr. Melbourne, Lindley Park, Mr. Strickland, 

 E. 11-11-06— galls." 



Habitat: Melbourne, Victoria. 



Types: In the National Museum, Melbourne, two of the above specimens on a card. 



COSLOCYBOMYIA new genus. 



Differs from Coslocybella Girault in having the antennee inserted below the middle of the 

 face, on the clypeus or nearly, and they are stouter, more clavate, the three ring- joints more 

 graduate into the funicle. Also the axillae are rather widely separated, not extending mesad of 

 the caudal ends of the parapsidal furrows as in the other genus. The postmarginal vein is 

 somewhat longer than the marginal, subequal to the slender stigmal. Mandibles tridentate. 

 Seutellum flat, not convexed and projecting above a declivous propodeum as in Coelocybella but 

 plane with the plane propodeum and with a narrow sclerite between it and the postseutellum. 

 Segment 2 of abdomen occupying about a fifth of the surface. Caudal tibiaa with two spurs. 



1. CCELOCYBOMYIA SEXFASCIATA new species. Female. Genotype. 



Length, 2.20 mm. Orange yellow; pronotum, sclerite just caudad of seutellum, post- 

 seutellum and propodeum, pale lemon yellow. Wings hyaline; face of pronotum, sutures of 

 thoracic dorsum, portions of the propodeum some distance laterad of the meson and six con- 

 spicuous stripes across abdomen from base to apex, black. Venation pale. Antenna? and legs 

 yellow, the scape dusky above. Cephalic and caudal femora compressed, swollen but simple; 

 caudal coxa compressed. Thorax finely, transversely wrinkled. Caudal margin of seutellum 

 narrowly black. Cephalo -lateral angle of scutum lemon yellow. One spur of caudal tibia much 

 shorter than the other, both stout, not long. Scape somewhat compressed, the pedicel moderately 

 long; funicle 2 abruptly larger than 1, the others gradually enlarging in succession. 



Habitat: Kuranda, Queensland. Jungle, September 15, 1913, two females. 



Type : No. Hy 2753, Queensland Museum, Brisbane, a female on a tag, the head and hind 

 legs on a slide. 



2. CCELOCYBOMYIA NOVISEXFASCIATA new species. 



Female: — Length, 1.80 mm. 



Similar to sexfasciata but the mandibles are narrower, the first funicle joint (sixth of 

 the antenna?) only slightly longer than the third joint (twice longer in the type species) and the 

 general coloration is greenish yellow instead of a rich reddish brown. Otherwise, surprisingly 

 alike. The thin black line across apex of seutellum is not quite complete. 



Described from two females on a card with the species following, labelled " 11. Bred 

 from aborted capsules of red gum caused by a dipterous larva, Agromysa sp. ? 12-10. ' ' 



Habitat: Melbourne, Victoria. 



Types : In the National Museum, Melbourne, the specimens as mounted and a head on a 

 slide (with type head of the next species).
