 Queensland Museum at Brisbane. 



Hexanusia, new genus. 



Runs to Zooencyrtus, but mandible 3 truncate, wide but not 

 very. Dilation of scape distad and not great. Scrobicular 

 cavity large, forming a horseshoe. Frons moderately wide. 

 Marginal two and a half times longer than wide, a bit exceed- 

 ing stigmal, which somewhat exceeds postmarginal. 



Hexanusia nigricornis, new species. 



Black, aeneous, and like the as yet manuscript Australen- 

 cyrtus genotype; tips tibiae (widely in 2), knees except hind, 

 tarsi reddish yellow ; wings clear, veins black. Frons finely 

 scaly, and with only two widely separated rows of pin- 

 punctures crossing it. Funicles quadrate, but 1 somewhat 

 longer, not quite equal pedicel ; scape black. 



One female, VVynnum, Queensland. 



Perilampus tassoni, new species. 



Green ; knees, tibia 1 beneath, tibial tips, tarsi, tegulae and 

 flagellum save pedicel, reddish. Punctate; parapside centrally 

 toward caudal end with a small, finely lined, impunctate area ; 

 occiput finely circularly lined ; upper face thick, with distinct 

 pin-punctures; vertex same, the ocellar area cross-lined; ocelli 

 in a curved line. Middle face smooth, ventral line upper, also 

 clypeus, but punctures sparser. Lower cheeks finely circularly 

 striate, with scattered pin-punctures, along the eyes smooth. 

 Postmarginal about twice the stigmal, about three-fourths 

 marginal. Propodeum with a pair of median carinas, from 

 thence nearly to spiracle, microscopically longitudinally lined, 

 thence laterad gibbous and punctate. Abdomen 2 from caudal
