alutaceous, sides with curved strise ; the rest closely reticu- 

 lated, more finely on sides of metapleurae. Pro- and meso- 

 pleurce opaque, finely rugose, a clearly defined striated band 

 down apex of propleurae, bounded by keels at base and apex ; 

 reaching to shortly below the middle : a similar, but wider 

 band down apex of mesopleurse, with the striae longer and 

 more widely separated, and bounded behind by a keel. 

 Abdomen smooth, first segment longer than the others united, 

 curved, becoming gradually dilated, obliquely upwards 

 towards apex ; ovipositor nearly as long as body. 



Comes near to .4. planireps, Szep., and .1. biroi, Szep. ; 

 the former has the sheaths of the ovipositor black ; the latter 

 has them whitish only before the end, and the base of the 

 abdomen is red. 



Rose Bay, Sydney. Bred by Mr. W. W. Froggatt, from 

 the larva of Piesarthrius mdrninfUus. Avlanis ajnealis, 

 Westw., is a parasite of the same species {rf. W. H. Ashmead,

9. Black : antenna? fuscous ; legs except the hind eoxa^, 

 and abdomen except base above and sides to below the middle, 

 red, the blaok only on the narrowed part; wings clear hyaline, 

 nervures and stigma black ; third abscissa of radius a little 

 longer than second ; second recurrent nervure received almost 

 in middle of cellule ; second transverse cubital nervure widely 

 bullated. Length, 6; terebra, 7 mm. 



Sydney. Bred from the larva of a Longicorn beetle (W. 

 W. Froggatt). 



Antennae as long as head and thorax united, stout, basal 

 two joints red, third about one-quarter longer than foui'th. 

 Front opaque, punctured, more or less reticulated: vertex 

 finely, closely, transversely striated at ocelli ; sides at ocelli 

 almost impunctate, the rest punctured, but not closely, the 

 punctures being clearly separated. Mesonotum transversely 

 rugosely reticulated, the longitudinal striae finer than the
