 Antea, p. 178, table of genera, line 18, the word absent should read short. 



1. GYROLASELLA SPECIOSA Girault. 



Antea, p. 167, line 4 of the description, side read margin. The marking on the scutum 

 is like the Greek letter Tau of the lower ease and on one side the arm is not joined. The 

 stripe across the propodeum passes over the spiracle, partly embracing it. Funicle joints 

 subquadrate, the club with a minute terminal spine. 



Forest, December 27, 1912. Type on a slide. Length, 1 mm. 



2. GYROLASELLA FASCIATA Girault. Genotype. 

 Length, 1.50 mm. Antea, p. 166, line 4 of the description, distal apex read dorsal aspect. 

 Densely polygonally reticulated (thorax). Reared from Eucalyptus galls. Types on a slide. 

 Cephalic axilla metallic green. 



3. GYROLASELLA CONSOBRINUS Girault. 



Length, 2 mm. A stripe across cheek ventrad of eye. Scape striped obliquely with 

 metallic. Reared from galls, forest, December 12, 1912. Types on a slide. Line 6 of abdomen 

 with a line-like caudal offshoot on each side of meson; 7 consisting of a round dot on each 

 side of meson and an area at each lateral margin. 



4. GYROLASELLA SPECIOSISSIMA Girault. 



The types are on a slide. They were captured May 2S, 1912 in forest (1,300 feet). 



5. GYROLASELLA LINE AT A Girault. 

 Length, 1.75 mm. ; slender. Median line of caudal half of scutum metallic green. 

 Also the meson of each axilla except at each end. Line 5 of abdomen curved convexly 

 cephalad. Polygonally reticulated. The type is on a tag, the head on a slide. 



6. GYROLASELLA QUADRIFASCIATA Girault. 



A species of Pseudiglypliomyia which see. 



7. GYROLASELLA VIRIDILINEATA (Froggatt.) 



Caslocyba viridilineata Froggatt in antea, p. 271. 



8. GYROLASELLA GRACILIS new species. 

 Female: — Length, 1.90 mm. 



Similar to viridipronotum™ but the marking on the scutum is shaped like the head (side 

 view plus part of stalk) of an ordinary pin, extends to scutellum but the " head" is separated 



19 New species. Female: — Length, 1.85 mm^ Honey yellow, the wings hyaline, the body marked with bright 

 metallic green as follows : Pronotum, scutum except lateral margins narrowly, meson of scutellum rectangularly, the 

 green not extending quite to the lateral groove, a longer than w:de spot at mesal base of postscutellum, mesal 

 half or more of each parapside, axillae except lateral and caudal margins, propodeum except transversely just cephalad 

 of the spiracle, immediate base of abdomen and seven thin cross-stripes, the first four close together (2 and 3 more 

 prominent, crescentic, 3 embracing 4), 5 broader, joined narrowly to 4 along meson ; 6 caret-shaped ; 7 near apex, 

 narrowly interrupted at meson : a dot at edge between 5 and 6. Eyes convergent, the facial margin convex 

 Ocellar area, a large, cuneate spot on vertex caudad of eye, pedicel above and a longitudinal stripe along upper side 

 of scape ; meso venter, hind coxa above at base and cephalic femur ventrad, also green. Propodtum noncarinate. 

 Mandibles trident&te. The male is similar but stripes 1-3 of abdomen aTe confluent.

 on gum. 3.11." 



Habitat : Melbourne, Victoria. 



Types : In the National Museum, Melbourne, the above specimens on a card and a slide with heads and female
