above, not converging. Temples short. Prothorax large, 

 quadrate, as long as the mesothorax, which has distinct fur- 

 rows ; these are straight, and converge towards the apex. 

 Scutellum large, longer than it is wide at the apex ; that is, 

 broadly rounded and margined. Postscutellum large, nar- 

 rowed gradually behind. Metanotum short, little developed, 

 the centre depressed narrowly, the sides broadly rounded, the 

 slope oblique. There is an oblique furrow across the meso- 

 pleurse. Abdomen shorter than thorax, longish-oval, dis- 

 tinctly narrowed at base and apex, not petiolated. Marginal 

 nervure long, the postmarginal longer than it ; stigmal fully 

 one-half the length of the marginal. Legs stout, pilose. 

 Body metallic-green ; its sculpture fine. 



I can refer this genus only to the Eurytomince, but it is 

 certainly not typical of that group. The marginal nervure, 

 for example, is much longer, the sculpture much finer, and 

 the antennae shorter and more clavate. I cannot place it in 

 any other group. The metallic colour is not unique for the 

 Euri/tomince, for it is found in Chryseida. In habits, the type 

 of the genus agrees with most Eurytomince, the species of the 

 tribe being mostly parasitic on gall-insects. Probably the 

 discovery of the male may throw light on the systematic 

 position. 



Chromeurytoma clavicornis, sp.n. 



Dark green, largely tinted with blue, and, to a less extent, 

 with violaceous ; antennae, and legs, except the coxae, rufo- 

 festaceous; mandibles and palpi testaceous; wings hyaline, 

 nervures pale testaceous. 9-Length, 4-5 mm. 



Bungendore, N.S.W. ; bred from Eucalyptus galls; August, 

 (W. W. Froggatt). 



Vertex below the ocelli finely, closely striated ;. apex of 

 pronotum, mesonotum and scutellum finely, closely striated, 

 the striation stronger on the scutellum, weaker on the base of 

 mesonotum; postscutellum microscopically striated, the parts 

 bordering it fiery-red, Metanotum smooth. Metapleurae fiery-
