 p. 308, S . 



S . Antennse shorter than the thoi-ax and median segment 

 combined ; pronotum much narrowed anteriorly, shorter than 

 the scutellum. First dorsal segment as broad at the apex as 

 long, a little shorter than the second segment. Seventh dorsal 

 segment subtruncate at the apex. Keuration similar to that of 

 A . australasice, but the position of the first recurrent is variable — 

 it is received beyond the middle of the second cubital cell in the 

 type, but at the middle in another specimen. 



Black ; the base of the mandibles, part of the clypeus, the 

 pronotum very broadly posteriorly, and the tegulee yellow ; 

 legs ferruginous. Wings hyaline, nerviu^es fuscous. Calcaria 

 white. 



Length 11-14 mm. 



Hah. Perth, West Australia.

c? . Pronotum narrowed anteriorly, nearly as long as the 

 scutellum. First dorsal segment as broad at the apex as long, 

 no longer than the second segment ; seventh dorsal segment 

 narrowly truncate at the apex. Second abscissa of the radius 

 shorter than the first, the two combined much shorter than the 

 third. First transverse cubital nervure longer than the second, 

 very sharply bent near the cubitus ; first recurrent nervure 

 I'eceived close to the middle of the second cubital cell, second 

 beyond one-quarter from the base of the third cubital cell. 



Black ; legs ferruginous ; mandibles at the base, scape beneath, 

 pronotum very broadly posteriorly, postscutellum, and a line on 

 the anterior tibiae yellow. Wings hyaline, nervures fuscous. 

 Calcaria whitish. 



The hind tibise are almost smooth, the spines nearly obsolete. 

 Keuration of hind wing as in A. australasice. 



Length 7-8 mm. 



Hah. Cape York, Queensland.

 S . Pronotum shorter than the scutellum, not very strongly 

 narroAved anterioi'ly ; scutellum with a delicate carina from the 

 base to the apex. First dorsal segment nearly as broad at the 

 apex as long, very little longer than the second segment ; 

 seventh dorsal segment broadly subtruncate at the apex. Hind
